Condo Collapse Simulation | Champlain Towers South Surfside, Florida, Miami [8K]
HTML-код
- Опубликовано: 27 сен 2024
- On the 24th of June 2021 at night the Champlain Towers South, a 12-story beachfront condominium in the Miami suburb of Surfside, Florida collapsed partially. This collapse simulation was made based on the presently available data, eyewitness, and video accounts.
The authors are independent researchers and impartial hoping to constructively contribute to the fact-finding. This study demonstrates the collapse mechanism assuming the following plausible hypothesis:
According to the data, the basement deck showed signs of extended soaking for many years. The problem was locally insufficiently patched and not rectified in its entirety. The wetting caused the deck ceiling to be weakened to such an extent that basement pillars punched through the deck where additional load had peaked at the planter area.
The authors hope to not distress relatives of victims with the application of dummy dolls in this simulation that have the sole purpose of tracking victims in potential cavities within the debris.

Friendly reminder: Conspiracy theories are not real! Odd ideas of bombs, direct energy weapons, John McAfee, and whatnot are nonsense.
But I swear! The internet told me 5G did it! The internet has never lied to me, so it must be true!
Agree. Please add "Climate Change made the condo collapse" (Sleepy Joe - The White House) to the list of nonsense. ... Addendum: stemming from the Alps region (EU), concrete work in the US always made me shudder. Corrosion, spalling, sharp corners in stress zones and small safety margins and the lack of skilled workers on-site / competent maintenance apparently DO have an effect after all...
On June 24TH there was a full moon. Maybe the already degraded infrastructure just couldn’t handle the gravitational forces of the full moon that it was just the last star that broke the camels back. It’s the moon. 🌕
So many just wants the world to be an overly complex system where everything happens for a reason. That reason being someone, somewhere is in charge.
In reality, poor maintenance is a reason. Poor descisions by people who weren't looking more than 5 years and resale were a reason.
But a paintshop circling followed by nonsense is just easier to believe than sometimes, people just die and they didn't deserve it.
Correction: simulations are not "not real" - not what really happened. Conspiracy theories are explanations. Often there are no solid reason to discount a conspiratorial explanation, and sometimes there is confirmation of such an explanation. But if a tree falls in the forest and the media calls it a "conspiracy theory" - did it really fall?
I lost my husband in the Hard Rock Hotel collapse in New Orleans and I try hard not to watch videos like this because all it does is raise a lot of questions and pain. My heart goes out to the families and I pray for them everyday.
I am so deeply sorry for your loss!
I’m so very very sorry for your loss. God’s peace be with you.
Prayers
I’m so sorry😕 I live in New Orleans as well so I saw first hand of how it was poorly handled 😒 God bless you & your family 💗
🙏🏽
You read about the collapse and the hundred or so people that have lost their lives, but seeing that final shot in this video really puts it into a chilling perspective.
I agree.
A man who was first on the scene said that he heard a cry for help and when he saw this small hand sticking out from the rubble, as he ran up to it. It belonged to an 8 year old boy who was begging the man not to leave him. And he stayed with the boy until help arrived.
If that alone isn’t enough to make this accident chilling. Then you should hear that the building was survey in the 1990’s and it was found that the building had sunk 2mm from when it was built.
The boy was 15
@@1LEgGOdt the 15 year old boy met the first responders this past week. You wonder where his unit was and how he was intact from when he was in bed when it happened to in the midst of rubble when the building collapsed. His guardian angel on earth was there. A hero in my book. Love to hear the boy’s story of the magnitude of the collapse when he’s ready to share his story.
@@melaniebuford He was on the 10th floor. 1009 I believe.
Building codes matter. Engineering matters. Report structural cracks.
Nothing matters when dealing with selfish and stupid individuals. By enlarge, this self inflicted event can be avoided if they choose to do the structural repair back in 2018.
Report structural cracks? Isn’t there mandatory inspections? Especially aged buildings.
Just say no to structural crack-s....
It wasn’t a crack… every single column in that building was not reinforced with any horizontal support. Pretty much poured concrete with zero reinforcement beneath it… it’s like building a bridge with just 4 steel pillars and the rest with concrete. The concrete not being reinforced with steel beams and the bridge breaks in 2 with the first bit of weight bearing bearing down on it. The concrete literally just falls apart. To put that into perspective, you take a piece of clay, flatten it and then play it across a gap then push down on the middle.. it splits in 2. Now reinforce it will 4 popsicle sticks and some gauze pads, it becomes much harder to crack.
The problem is that they mounted 20 floors of concrete on top of literally not properly reinforced concrete.. they believed the vertical beams and concrete would be resilient enough to hold on each floor. They didn’t brace the building with horizontal beams between each column and they didn’t reinforce the concrete with horizontal beams either. Now apply that to every single floor and you get something resembling a table with just 4 legs at WWE that gets slammed on and breaks right down the middle. Hell, or taking a 1 foot by 1 foot by 2 inches thick piece of ice and then setting it on 4 wooden poles and then placing a 40 lbs weight on it without freezing horizontal beams between the ice or underneath it and expecting it to hold the weight while the weight shifts constantly on it. That’s why it’s important to not cut corners and get a few good engineers to check over one another for flaws in design..
@@mr.honeybee7661 thank you for the detailed explanation, made it very easy to visualize
There’s probably a lot more aging buildings in this condition. Nobody wants to hear that their real estate is worthless.

Amen. I hope the majority went while sleep. No suffering no pain

This makes me cry... I hope the children continued dreaming and never woke up...
Unfortunately, some suffered. Rescuers heard a woman calling for help for hours but couldn't get to her, she died hurt, scared, and feeling abandoned 😭 RIP
4:00 That X-ray view of people inside the collapse really gives me chill to my spine.
Makes it more real for me; knowing where the people were and what they were doing (i.e. in bed, standing, walking) all makes it real.
The last image is heartbreaking.
I can't imagine. I heard that the victims were decapitated, I was so confused as to how. Looking at this now, I am horrified
No.
I honestly wish I never saw that image, I have regrets after seeing that shot.
Right?! The little yellow silhouettes even get bent and contorted. Horrifying
@@ghrvjdev it's cg it isn't even graphic. Your brain gets traumatized by tpose cgi? Yikes
Seeing the people inside the structure really drives it home. Incredibly eerie. May they rest in peace.
In the actual video, you can see lights turn-on in the 2nd tower, and flashlights moving around. People were awake, but confused what was happening. (Then the tower collapsed.)

Resting in pieces, they are. Fucking mangled.
Not sure how many survivors were in the bottom floors but most virtually had little chance, lessened by collapse of the other half on top. See some people are bit upset about animated people being on this video but it was included to give viewers idea of the scale of debris search and rescue now sadly body recovery, have to dig through. R.I.P to all the victims
well said.
I was one of those upset, I thought how thoughtless to do something like this, then as the video completed... a reality set in... and a truly sobering awareness became evident. I withdrawal my judgment and hold this a helpful but painful gift of perspective.
And would explain why they wld be last to be recovered being that they were at the bottom of the bldg..
@@lookingforwyatteearp3137 obvious troll is obvious
I was wondering if those were the areas, the Israeli's plotted out, where the most likelihood of recovering anyone.
This was so hard to watch but gives us a much better idea of all the things that happened along the way. If there was a blessing it has to be that the remainder of the building did not collapse and saved the lives of many more. Thank you for putting this together.
The Shear wall near the elevator was the only thing that saved that portion of the building.
Those poor people, I’m sure the last thing they worried about was their homes collapsing around them until the last moments.
I think it was known there were problems with the structure that could lead to this. They were reported by engineers in 2018 and again recently, at least that's what the New York Times said. They even had plans to fix the problems in a renovation soon, but I guess that the people who lived there still didn't think something like this would happen. I know I wouldn't as long as the building still looked "solid" to my eyes. If the people who lived there were notified at all...
> "I’m sure the last thing they worried about was their homes collapsing around them"
Did a crystal ball tell you that, Sherlock?
Absolutely Tragic.
I am Still Angry about This.
Those Poor Innocent People That Died.
The decades of neglect and major problems within this building were not being addressed correctly and fixed ...ultimately taking its toll..
but you would have to go back decades when the sinking and leaking began..
Some of the dead owners who refused to do repairs were in there.
@@gc99289 🥲
It makes me angry too. The people who are supposed to do regular maintenance completely neglected the safety of everyone living there. This could’ve been avoided if they would’ve done their job instead of trying to sweep potential safety problems under the rug. Absolutely infuriating
@@notgreatnotterrible48years63 It's quite likely that there were hidden problems not actually known, because not even the experts that examined the building expected it to fail. So the known problems just contributed and speeded up the time of this final fail.
When the debris has been removed, they will spend a lot of time to figure out the state under the ground, i.e. the piles and pylons.
My Prayer to those who loss their life or lost Family members. This was a horrific collapse...unbelievable. This dramatically shows the horrow.
What are your prayers gonna do? Those people are dead.
Prayers won't help those that died in this tragedy. They are either present with the Lord (Jesus) or burning in Hell for eternity.
Why you pray for those who perished? What's done is done. You can not change anything. Unless, you pay well your catholic priest so he can sand everybody to the paradise. They have a special connections with haven's officials and simply bribe them..
@@Anthony-vx1tx catholic priests don't have any special connections. No one can be your mediator between you and Jesus. (I'm Baptist)
I know it must be horrible finding all the it must be horrible finding all these bodies. Bodies that have been crushed and flattened by the concrete.😣 You are never never supposed to die in your home in your bed
So sad. I am going to think about this every time I am in a hotel or condo with a park deck below.
If you haven‘t got other things to think about, you’re probably fine.
Buildings like these have existed over decades and as you can see these rarely happens
If you truly are going to a hotel and co do just check for structural cracks and avoid those buildings easy as that
Like I said they are so rare that you have a higher chance of getting killed while driving
@@JustJohn505 That’s good to know cause when I was on vacation in Mrtyle beach I was thinking of this
Park deck below has virtually nothing to with it.
I'm going to think about this every time I hear someone praise deregulation.
Eerie to watch, especially when the human figures are added at the end. Such a tragedy. Visualizations help one to understand and process it. Still questions about what happened first on the lower levels and why it happened at that particular time.
Exactly 😢 I am thinking the same, and wondering if anyone didn’t notice anything earlier 😢 more I watch this more I cry 😭 this was very sad 😢 😔 😔 all those people who went to bed and never woke up 😢
It is gruesome just consider, but seeing something visually is the best way for me to learn. At least to learn without having to see the physical ruins of and devastation of the bodies in the building. RIP
Water inadation sub foundation. Is how it happened. The buildings maintainace crew kept telling the owner that subsurface water was entering into the basement area. They just kept telling them to pump it out. When a building inspector should had been called in.
I honestly think they should've left that part out.Obviously we know there were people there but sheesh we don't need a reminder.Its Just my opinion the fake people should've been left out.
@@ur.highness that wasn’t the point of the video, the autor is definitely trying to give us a idea how far the bodies of the victims were buried in the debris. Giving you an idea how hard was to get to them, the idea is to educate the public, there ain’t a soft way to do it beside going straight to the facts and being raw about it. A very sad event…
Thanks to All those involved in using this amazing software technology which will surely enhance and add an additional perspective in this most urgently needed prompt investigation.
Also, a thank you to everyone who has been and continues to help (in many ways) everyone affected by this horrific tragedy.
That is false, this animation contradicts the actual video evidence of the collapsed pool deck recorded by people from the adjacent hotel. That happened minutes before the main collapse. Everything in this video other than the general outline is false and contradicted by actual evidence. See the channel of Jeff Ostroff if you give enough of a shit to see real engineering in action.
Chilling at the end with the simulated people however most of them likely would have been lying down when it happened. RiP. So frightening.
Powerful animation. Thanks for your work. That had to take many hours.
I'm think many, or most, were asleep.. and by the time the awakened they wouldn't have made much sense of dream or reality ... and then just .. perished very immediately.
The scriptures say that:
"to be absent from the body is to be present with the Lord"
🙏
@@RLaraMoore For those who REPENTED that is. No one is and will NEVER be present with the Lord unless they've REPENTED BEFORE! DEATH!.. Please understand this and make it clear. Many people are and will go straight to hell for ETERNITY believing this verse that's obviously taken out if context.

Good simulation. We have to remember the pool deck dropped first, according to the video and pre-collapse 911 calls. The authorities should refer to this simulation as part of the forensic investigation.
Thats what he showed you dummy.
@@lookingforwyatteearp3137 not really. It shows the deck falling but it’s an incorrect assessment. The actual deck didn’t bring down the building. The deck alone did not collapse any columns. It was the planter locations, above key columns that actually brought the building down. If they didn’t have 9,600 lb planters along the building main support columns, the building would have survived. (I really hope you argue with me on this,) To a casual like you, I’m sure those key details aren’t important.
@@dartheverstar9564
Right at the failure point there was a beam that should have been sitting on top of two pilings, supporting it and the ocean facing wall. Seen in the video shot in 2020, the beam is actually sandwiched between the pilings not on top. In the video you can see the beam sagging. This was directly underneath the ocean facing wall, just about where the large planters on the pool deck were.

@@lookingforwyatteearp3137 It is better to remain silent and be thought a fool than to speak and prove that you are, indeed, a fool.
So STFU you fool.Your ignorance is showing.
As an engineering student, this gave me a really intense chill up my spine. I can tell that from the beginning this building had issues and they are evident in the 2018 Morabito report and the Garage video from 2020. Unfortunately they were merely shoved beneath the carpet, and this proved to be fatal. This goes on to show how important legitimate building inspections are as well as a dash of common sense. May the 97 souls lost in this tragedy rest in peace.
what did you see in the beginning aside from the obvious collapse of the building? Is it a structural flaw that was there from construction?
The place was a big bath tub floating in saltwater. Any cracks in the concrete would lead to rusting and degeneration of the rebar and failure.
@@bigwheelsturning oh was high sea water table causing it to be unstable? If so what would be the proper design/materials to use?
thanks for your response
This is going to be a case study for sure. Safety regulations are non-existant or neglected untill something really bad happens.
@@Graymenn Spawling of concrete in the basement indicating that the slab was overloaded and or severely deteriorated to the point that it's load bearing capacities had been affected. Stalactites formed in the roof indicating water infiltration, and various cracks were seen, some which had to be sealed up in a hasty manner with a urethane based epoxy. Aside from this the rise and fall of the water table would cause soil consolidation which would in simple terms reduce the density of the packed soil around the piles (Support columns embedded into the earth). Eventually over the years enough soil consolidation would occur to create a void beneath the basement garage slab and the soil itself. This void would fill up with water when the table rose. This would in turn seep between the piling caps and the garage slab and thus flood the basement. This would explain the numerous reports of constant parking level flooding. Add to this the other factors within the soil such as the sinking rate and the poor maintenance and you have a potentially destructive chain of events.
If all it took was the pool deck punch throughs to bring it down, I'd imagine we'll see more like this in the future, since high rise condos in Florida started popping up around the same time, right? I wonder if hotels/resorts are better managed and structurally maintained than some of these condos. I keep hearing about underfunded reserves. I know condo associations are often fraught with drama over funding and repairs. This disaster just feels so avoidable.
the pool deck was supposed to be slopped but it wasnt done when the project was finished
She has a twin sister two buildings to the north. People are already starting to move out out of fear. Can't say I blame them..
My parents owned a condo next door at Champlain Towers East about 200 feet away from the South Tower that fell. They owned from 1993 thru 2013. The parking garage was always flooded with water, and the maintenance crew were always pumping out the brackish water from the garage. Always found that strange at the time, never gave it much thought. I hope the engineers are looking closely at that building and the North tower building as well. All were built by the same developer.
@@daleyoung87 lmao no they aren't. I've been watching the condo prices for CTN and nothing has really popped up, and they still cost $980k
Most if not were built correctly
The garage near ramp crumbled first (garage on tourist video 7 minutes before collapse) - pool deck within minutes of that, lending to complete instability of that section. I agree the animated bodies was disturbing, but necessary to grasp the real scope of the disaster.
Definitely as a matter of showing what the scale of the rescue and recovery effort had to be, it was useful although very sad to see
The perspective of that video is a bit misleading. The ramp is much longer than it looks like on that video and if you take look at the drawings of the building and count the pillars the crumbled roof you see in the background is actually the pool deck.

That building came down like a game of Jenga. It's a shame that the conditions that led up to the collapse weren't properly addressed in a proactive manner. This is what negligence and complicity leads to when needed building repairs are ignored.
It never should have been built that way, with the pool deck tied to the building support columns. Once the pool deck came down, it knocked down the columns for the center block, which then knocked down the right block's columns. The left block stood standing because it had much thicker columns that could withstand the extra load.
@@fallinginthed33p Completely agree but this has been a standard norm here in Florida. It's not an ideal design because water is extremely heavy and requires a stronger support structure to hold up the loads and stresses. Once the rebar and concrete supports go, there's no stopping it.

Thank you to whoever took the time to put this digital reconstruction of the technical mechanics of this tragedy together.
Can't help but wonder if there's a crushed car in Champlain South parking garage rubble with dashcam memory card of parking mode (or Tesla Sentry Mode) footage of garage collapse
Very good point. I hope this question circulates amongst the former residents who by Gods grace managed to escape that death trap.
there are many security cameras in the garage and pool area and other areas, whose footage has not been released. The security office was in the left standing part of building and/or the footage is "in the cloud" somewhere, so those should tell more . Unless they were all off, which possible but not likely , I would hope. I do have to wonder why the security guard did not immediately throw the fire alarm though, after the initial pool/garage collapse, building had power till it fell 7minutes later.
Why not securtiy cameras in gargage? Lobby? Most condos have such systems. Where's the footage?
@@a.j.patron9214 In the owner's/condo assoc's possesion would be my guess , until I assume goverment filed supenas get served, and they go through the condo''s lawyer's then final release being decided by courts and/or gov offices. Possibly the footage was acquired by the police during/to aid the rescue effort, but it obvious there are some legal issues why such vids are not public, and might not be for a while. As they may show liabilty, and will be used in future court/legal proceedings, and some will be supressed by non-disclosure rulings- such as ones showing people getting killed.
You will never see it
When the building inspectors inspect from now on, you can bet they are going to report EVERYTHING. Then the condo owners get so many days to fix it all. Who’s going to do the work with the shortage of employees? If the work isn’t completed, are the owners going to have to vacate the building? What a mess!
No they won't as they will be like me threatened with their jobs. I said fuck them and then they found away to get me back.
The problems with the pool deck _were_ reported in detail and did not mince words. Engineers noted design flaws and failing waterproofing that would lead to "exponential damage" if not repaired. It's unpopular to levy such huge maintenance fees on the condo owners. Human nature is difficult to change - nobody thinks it's going to happen to them. If money was no object to the victims, it likely would have been repaired sooner, but money _is_ important to people. I'm not blaming the victims - I'm blaming human nature. They certainly didn't want to die.
Seeing the people brings chills ...they didn't have a chance :(

Really sad to watch what happened to innocent, unsuspecting people. I feel so brokenhearted for these families.
The best simulation of this kind I have ever seen. Thank you for sharing your hard work. It would be nice to see a timeline with it...
Thank you Kostack! I've always wanted this to be made! Maybe the investigation can use this simulation.
I hope it was at least quick, may they rest in peace.
It’s sad because it happened around 1am. So most people were asleep when it happened.
No Survivors on lower floors.. only the top 3 levels.. where the young boy was pulled out..Excellent Visual. Shocking to see how people died. Blessings to each & everyone x
The teenage boy was from the 10th floor and the mother and her teenage daughter were from the 9th floor.
The woman who was alive for at least 12 hours after was staying in her parent's 3rd floor condo. It dropped into the basement/garage where a dumpster seems to have allowed a void, where she was trapped between two beds. Rescuers had to leave her because of a mattress on fire, I really hope they were not implying that it was her mattress on fire. Grisly, horrible, the whole thing. Suffocation would have been likely cause of death for most.
@@srhmcs1 No, crushing would have been the cause of death for most and it would have been quick.
This is so chilling yet, it shows that there was no chance of escape once the first few pieces collapsed!! It would be great, if all tall building have a system similar to seismographs..... that would/will notify residence of potential hazards. Cars have great ways to keep you safer...... large back-up monitoring, yellow flashing lights .... to know what’s in your way when merging, etc.
Surely something could be constructed to safe-guard people in their own apartments!!
This is so heartbreaking. None of us know when, where, or how we will leave this world. All we can do is try to live a good life and stay close to God. My heart go out to all the families that lost love ones. I pray for strength, healing and peace. May God keep his arms around all of us. 🙏🙏🙏❤️🙏🙏🙏
Follow!
That said, even with a seismographic warning system, it's very doubtful the people in this building would have had time to escape, even had they jumped out the window.
Total time to collapse (in live footage) was about 11 seconds, including a 4-5 second delay between the center portion of the building coming down, and the eastern portion.
When any part of the building fell, it did so in 3-4 seconds. Sadly, that's not enough time for people to respond, especially in the midst of such horrendous confusion as a building collapsing around them.
I heard one analogy that if they made it to the top of the building, more may have survived. They said the building did not go down like you were falling but more in a slower motion. The air conditioning units on the roof were in good physical shape.
We should all be outraged. More buildings will fall sadly. Checking them every 40 years is not enough. There is poorly built buildings everywhere
More buildings will fall? Based on what? You are using one example of shoddy construction that negated reasonable engineering *combined* with very very poor maintenance and neglect. This boiled down to negligence. An engineering firm in 2018 (unrelated to the 40 year electrical/structural recertification) recommended $9 million worth of structural work, which the condo board was still bickering over 3 years later- and the cost had ballooned up to $15 million for the repairs.
Thank you for putting time and effort into this video! Great work

Very ending where you see how humans land in the rubble. That's the most powerful. I can't even imagine the mind f*ck it is to be buried alive and surcumming to your demise. Please God let there have been angels with them. 😭
Hopefully, God was merciful in the midst of this horror and most of them died instantly. 😞 😢
@Fk Gooogle there is light, there is dark. There is good, there is evil. That's like saying "if the Devil is real, why good thing happen?" you clown

@Fk Gooogle I've seen the light of God, I had an experience and saw the boulevard of Heaven. I can assure you he is real
@Fk Gooogle Yeah its hard to reconcile.
This is how working at FEMA broke me. Arriving after a disaster, natural or manmade. The loss of property, lives, families. The shock of it turns residents into zombies that will suffer PTSD for years. And all we could do was listen and cut checks.
Oh wow 🥺
A listening ear and cash to feed and shelter a family is exactly what survivors need to start the process of rebuilding.
This was all preventable if the owners of the buildings took care of the massive cracks & water issues in the parking garage..so so sad, I didn’t know anyone there but it still makes me extremely sad 😢
The truth is that some people neglects cracks or water leakage issues in their houses, feeling less concerned without knowing that the repercussion would be disastrous
Where are you from Shelley?
I think more then "cracks" put that building down. Look at the frame 2:50 and look the space between the columns that support the deck and more yet the absence of beams connecting them. How long a "job" like that can stand?
I've been watching quite a few videos from engineers on this and while I'm definitely no expert, it does seem likely that there were fundamental flaws in the building's construction. So, while they should have maintained the building properly, the construction flaws would have eventually caught up with them.
@@aimeeinkling Correct. However, there is a sister building that is identical to this one that collapsed, built at the same time... just 3 doors up. Champlain Towers North. It went through it's own inspection at the same time the South Towers complex did, and passed with flying colors. So, somewhere, they cut corners in building this building, so it would be the original contractors who will be at fault, ultimately. Something tells me that they actually set this one up for demolition, and made it 'look' like an accident, so that any insurance settlements would go to the families of the victims. The fact that the judge overseeing the sale of this site is rushing it through already, is very suspect. They're trying to get rid of it before the investigation is even completed. That tells me there's something to hide.
Y'know, I don't post this to be cruel or unfeeling. I guess the victims who were asleep during the Surfside collapse didn't feel anything because they died in their sleep. They were the lucky ones. OMG, I can't imagine the SHEER TERROR the people who was awake were feeling during the collapse! It gives me chills, just thinking about it! God bless the victims and their families.
There's a chance that most of the victims who were sleeping woke up to the sudden shifting and get crushed 2 seconds later ;(
@@man.7237 that’s still better than what others experienced. Like the girl that was alive & screaming for help for 11 hrs before dying. That was a slow horrific death. Or the lady on the phone with her husband panicking and watching the pool deck sinking. Those who were in bed sleeping had it the best. Even if they were awoken , they were in the dark and had no clue what was happening before getting crushed within seconds. Still half asleep & out of it.
@@andrewsmith3095 true...
All those poor souls lost. The ending was brutal to watch.
By far best animation I have seen of this event, animations are awesome!
Whoa...that last one of the bodies laying in the rubble is brutal. Nice work on the vid.
Tacky.
If this is accurate, looks like pool deck columns over the parking garage gave way first and then pulled the neighboring parts of the building with them. May God give comfort to survivors and bless all those who lost their lives.
Pool deck gave way first.
No the pool deck " columns " didn't collapse first , the pool "deck " collapsed , the columns can be seen sticking out of the top of the deck, the concrete was not thick enough over each column to support the load , if there were cross beams between each column or thick pads over each column , this world not have happened. The pool deck was always going to exposed to the weather, and was not designed properly, the tolerances were too small. In my opinion.
@@kingdomfor1 Yes cross beams would have held the pool deck - obvious design flow.
@@kingdomfor1 there's also a ceiling beam where the entrance to the underground garage is that was not laid on top of the columns. It looks like it was a repair job and saturated with water. That was the area where large chunks of concrete started falling. That could have started the collapse of the middle part of the building and then with it in the same direction that was falling brought the deck straight down to the ground which caused the columns to puncture there. Could be. There are lots of plausible theories and any of them could be what happened.
@@kingdomfor1 Some of the pool deck columns didn't collapse _at all_ and were still poking out of the rubble near the pool a couple of days later.
Nice work once again, Kosack Studios. This is truly a terrifying prospect and I hope maintenance is never again neglected. I want to know what could be effectively done to prevent this disaster.
Damnitmann. I’ve watched the security footage of this collapse a dozen times at least. But the simulation here is freggin frightening. I’d have to agree with many comments in the thread section, anyone below the eighth to tenth floors have very little chance of survival. I pray it was quick but for some I know that wasn’t the case, God rest them all.
Good simulation and heartbreaking at the same time!
Still can’t believe they used toothpicks hold the whole building
Actually they used bigger beams in the part that stayed standing, imagine that?! Granted it had no water issues for 40 years softening up the concrete but still, why they used small columns on 1 side & bigger on the other is what I don't get..
@@Mandy_39 Probably to increase the parking area.
Columns are incredibly strong unless lateral forces are applied ( think earthquake). This design is used in many places without issues. .The problem with these was that they were weakened by rust and corrosion from salt water intrusion which caus them to fail.
@@lenjoplus There is also video from the parking garage showing 2 columns with a beam between them instead of on top of them like everywhere else in the garage. Its very very close to the area that is suspected to have collapsed first.
@@Mandy_39 most of the other side had pool deck, the side still up had all building.. thus needing larger columns
Its shocking that anybody was even able to survive at all. Thank goodness the other tower didn't collapse too. It is already devastating enough.
I had a feeling that eventually you would do a simulation of this collapse.
The time stamp at 4:00 through 4:28 was really hard watching it. My heart breaks. For all the lives lost and their families and friends. May God be with them all.
Rest in Paradise to everyone that passed away
What about those who don't believe in carpenter' story?
@@Anthony-vx1tx still hope everyone R.I.P
Outstanding presentation, but seriously creepy! The combined chill of that eerie music and the final frame turned my blood to ice.
According to eyewitnesses, and at least one video, the pool deck collapsed as much as 7 minutes before the main collapse. This simulation has it collapsing after the main collapse starts.
Its time lapsed on this video.
Great rendering, really puts it into perspective, great job.
Heartbreaking. "Sometimes in life there are losses. Losses that can never really be replaced. Losing you has been the hardest thing I’ve ever had to live with. I wasn’t ready to say goodbye. I wasn’t ready to let you leave. I would give anything for just one more day, just one more second. But I’ve learned to trust in unconditional love. Because the one profound thing about death is that love never dies. Some bonds cannot be broken. Because even though you’re not physically here, your heart is - it lives on within me. I carry your heart inside mine. I carry it on days when I discover something new. I carry it on days when beauty unfolds in the most unexpected places. I carry it on days when I find courage to heal and to grow. I carry it with me - always. Someday we will meet again - and we will no longer be separated by time or space. But until that day, I’ll find comfort in knowing that you are still with me. Your heart safely tucked inside mine. Some hearts just belong together and nothing will ever change that. I loved you then. I love you now. Always did. Always will. Forever in my mind. Forever in my heart. I will carry you." 🙏🙏
💕💕 this is very beautiful. Thanks for sharing.
Why would you build a building with stilt beams? Seems very dangerous.
its crazy because the part that didn't fall was on waaaaay thicker beams. that's why it didn't collapse even though a big chunk of garage collapsed underneath it. Not sure why they cheaped out with the rest of the beams. they made them really skinny
It's Florida, they have to or they will get flooded
In the first phase of the fall, there was an excess weight on the garage slab, which caused the slabs to collapse, which could not withstand the punching load. In the second phase, with the fall of the slab, the buckling length of the columns doubled. And lastly, any engineer knows the increase in pillar height causes a dramatic decrease in the load-carrying capacity of the pillars and this caused the third phase of the fall with the pillars now having twice the buckling length and no longer able to support the weight from the top of the structure, this caused the pillars to collapse and the building to fall
Don't forget the garage slab was also weak due to water penetration causing de-lamination at the top rebar (see core sample images) and considering the bad design meant the columns were 100% loaded when new the punch through that happened was inevitable barring any remedial action.
How, exactly, did the buckling length of the columns double? I thought it was the rotation of the edge beam (as the slab collapsed) that caused the collapse of the building.
Wow!, really helps see what happened,,those poor people never had a possible chance to get out,,,so sad,,prayers to all,,
This video is amazing. I have never been interested in engineering or buildings before. Never say never! Thank you for such a great piece of visual education- youre talented!
Heart-wrenching to watch, even though its a Simulation. God rest those poor souls.
This really opened my eyes to how badly people were trapped under debris, my heart is broken for all the people who lost their lives and loved ones.. gone too soon 😭🇺🇸
i just had a friend visit me in miami and i picked him up in south beach to drive to fort lauderdale. we passed by the surfside area on the way, and on my right when i saw the signage that located where the building used to be located, I said "Alex, look, there it is!" and he said "There is what?" and I said "Nothing. Nothing's there." The craziest thing about this collapse, and all building collapses, are the void it leaves and the absence of life echoing in the busy neighborhood.
This really broke my heart i cried when i saw the news it sucks seeing any human die especially under this tragedy 🙏🏼😢
Me too. Ripped my heart out.
I was already waiting for your simulation. The others are not very good.
I'm curious if it is conclusive that the massive concrete planters over the supports in the garage are not what collapsed first? Since the building collapsed 7 minutes after that collapse that was filmed from the driveway. From the woman's video you can see a support pillar is missing and the debris from above that is scattered as the water pipe drained water into the lower garage. What you see in her video is the massive concrete planter. From some reports the planters were not in the original plans and added additional weight and after the other reports that show the sloping was not appropriate only added significant water seepage to the slabs below. Very likely what the simulation should account for is the planter going first along with the pool deck, destabilizing the support structures which sloped the building toward the garage and dragging and shearing the rest of the towers with it.
U are so right. I have wondered a few things if anyone can help? First how many parking spots were there in total since they went further outward from buildings footprint. Secondly, those 8 additional parking spaces added on the pool deck that also broke away, did the hoa hire an engineer to see if this was going to be a problem? Third when they found the mattress lady what was her bodies location like, was she still located between 2 mattresses and the smoke from one of the fires killed her or did the fire get to her. Thanks.
The planters were no doubt one piece that brought it brown, but likely not the only piece.
This was a gremlin party, and they had a pizza delivered after midnight and everybody had a slice.
I'm not a 'computer graphics' fan, but when you have no other evidence (video/visuals), or need to get 'intricate', this is more than satisfactory! Very well done! The collapse from all angles, was superb! The unnerving part was at the end, starting @timestamp 3:55. This view depicts the real thing that matters most, the peoples, inside! Granted, the speculation doesn't have to be 100%, (the exact positions, of the residents, at the time of the collapse, as long as they're all included), but it puts the point in perspective!
there is video that shows it collapsing in 3 different parts
The video shows the building starting to collapse before the portion of the deck containing the planters fell. We know that the pool deck was collapsed BEFORE the building started to fall because a resident (standing on her balcony) who did not survive told someone over the phone that a portion of the pool deck had collapsed just before her phone went dead.
That's exactly what I was thinking: The punch-thru failure of the pool deck was what precipitated the failure of the south building columns which resulted in the larger building failure. This simulation shows random panel south walls of the first and second floor collapsing prior to the pool deck collapse.
@@johnpinion8033
Do you think the punch-thru failure on the pool decking next to the building occurred because the extra large planter fell through the decking into the garage? I do. I watched that lady's video of the water pouring out of the broken pipe down into the garage, and there is a dark object in the background that may be the broken up planter.
@@johnpinion8033 see Rako Studios channel recent video. He explains this theory and has visual evidence from that lady's phone video.
@@alicehallam8247 Pretty much. That seems to be where the collapse started. I believe the addition of much sand and pavers onto the pool deck in 2004 allowed water to constantly soak the slabs, weakening the rebar and leading to the failure. All planters were probably leaking water into the slabs also.
@@johnpinion8033
Agree. And the weight of the really large palm trees that were there until around 2017 (see Google Earth imaging) plus the weight of the water in the soil added more stress. Trees likely consist mostly of water, like any other living thing, like the human body...so the weight of the water in the soil, and the leaking water moving through the added sand and pavers. Seems like a recipe for this terrible event.
The ending with the people show the true devastation and horror that happened. Prayers for the families and friends.
People that get upset about videos like this need to be more aware of their option NOT to click play...I don't know anyone made to watch videos at gunpoint.
Adding the bodies into the images made it that much more terrifying
Imagine how much worse it was when the world trade center collapsed. Most of the victims here were asleep. The ones on 9/11 witnessed the horror.
Tragedy is tragedy. Why compare the two? How it happened doesn't lessen the pain and trauma these families and community are experiencing. Sending 💗 from 🇨🇦
@@ChristineChloe-sg7pu I agree. Thank you. ❤️
WTC buildings had people jumping from broken windows to their death !
Muy buena simulación me preguntaba como habia sucedido, lo siento por tantas victimas y sus familiares Dios les de fortaleza y paz.
I was alive for 911 and remember it vividly, but something about this collapse struck me. I hope this never happens again. I have been to Miami many times and been in many high-rise buildings like this and never even imagined this was possible. I wouldn't want anyone to die like that, in a pile of rubble. Hopefully it was quick because you can only think of how terrifying that must have been. God bless the ones who passed away.
This was a horrific tragedy on all levels. On a much smaller scale compared to 911 when the trade center towers collapsed. My heart goes out to all the ones who lost their lives and the families of their loved ones God Bless! Also to all the first responders and rescue efforts for the weeks following.
If I’m not mistaken the pool deck collapsed a few minutes prior to the rest of the collapse didn’t it? Just curious.
3 min before
@@Brian-ij9to i thought it was like 6 or 7 minutes before?
At least the garage entry had that pile of rubble (possiblely a collapsed column) and broken water main visible about 7 minutes prior. I just figured that occured with the pool deck collapse...
@@ChadDidNothingWrong remember the columns from the bridge that collapsed in florida a few years ago because there was a thick column at one end and a smaller column at the other end and cracks appeared at the end of smaller thinner column and eventually failed this is what happened and thats why the rest of the building didnt collapse
What's disturbing is the number of people who have heard about this in the news but thought no one or just a few people died. This was an in-service residential occupancy building that fell in the middle of the night....wish this video had played on all major news stations the morning after it happened to drive home the point that those 150+ people aren't just "missing"...
The last part as chilling as is could actually be usefull in recovery training
How is an inaccurate computer model going to be useful in recovery training?
@@rickgeller6043 its literraly showing you where the bodies are at. Duh. Lol
@@jaimemendoza1212 it's not showing specifically where the bodies would have been located on a person by person basis. This is a simulation, so the victims' remains locations in this video are a guesstimate at best. No body truly knows the exact positioning of each person in that building when it fell. Most likely, they would have been in their bedrooms, sure. But some may have been in the kitchen making a midnight snack, binging their favorite show in the living room, taking a shower, using the stairs and elevator on their way back to their condo, parking their car in the parking lot underneath, etc. This simulation would be useful though in seeing where each unit would have ended up in that pile. So that would be useful in locating the missing based off where their specific condo unit would likely have fallen. But the placement of bodies in this video is not accurate to where those victims were actually located in the pile.
@@jessiarcana4416you dont say...
Its like the whole fucking building was being supported by chopsticks.
The building was built well and too code, maintenance was the real issue.
Every building looks like that.
I agree. Thin pillars sitting on a sand foundation. Nuts to build it that way. I thought it was an ugly building and the foundation added nothing, took away even.
Good analogy.
I'm over huge buildings ... we build some of the biggest hospitals in the world... this building was built good.. there is more to it they ain't telling... something structural was done to make it fall.. hope they have investigation.
These ppl played a game of Jenga with ppl’s lives. Incredibly devastating!
All civil engineers have to play a game of Jenga with people's lives. It's just that most don't lose.
@@sudonim7552 :(
Very well done animation. How sad, they must have been so scared...
Always had an interest in failure analysis. Chilling. Those poor souls.
The stairway wall stabilized the East section for 7 seconds longer than the mid section & then it fell. The elevator wall allowed the mid-section to shear from the West portion which remained standing until they demolished it.
Sadly the simulation fails to take into account the detonator charges that are clearly seen in the actual video footage recorded from the building next door.
I thought it was seven minutes after the pool deck collapsed the rest came down. Or part of it came down in the garage.
You are not watching an official simulation!
The simulation brings reality to the sadly unimaginable, makes one wonder if this collapse was preventable, at all?
The building should have been condemned, based on MC report, in 2018 !
Definitely preventable
Thank you for contributing this apparently plausible and well animated rendition of the collapse, helping grasp how a modern building could collapse, given so much experience building such structures. I was struck by the almost complete lack of support between floors by anything other than pillars, not supporting walls, which would also lend significant diagonal support as well. Was this animation an accurate reflection of that apparent "feature," that few, if any supporting walls were involved within the entire basement, and perhaps all the floors above, since that is what appears to be the case in the animation?
Sadly yes, basically all structural support was done on 24"x24" pillers to the west side with smaller 24"x12" columns to the east, and the only horizontal stability the place had was the pool deck, and staircase walls, as it along with the property retaining wall contributed a lot to shifting horizontal loads on a sand bar to boot. Poor design is an understatement. Only question at this point is how the heck it managed to survive more than 40 years.
I got engaged in front of the towers just 2 months before this while on vacation and staying right next door. I still remember looking and seeing the families on the decks that morning and I cringe thinking of the probability those people didn't make it.
Maybe some people on the top floors may survive but this simulation just gave me the chills. So sad!
I believe a 14 year old boy was the only survivor of the collapsed section, sadly his mother did not survive, RIP
God bless their souls 🙏🏾 can’t keep this horrific event off my mind
