Engineering Connections: Earthquake Proof Bridge (Richard Hammond) | Science Documentary
HTML-код
- Опубликовано: 23 сен 2024
- Richard Hammond reveals how engineers made one of the longest bridges in the world earthquake-proof - . Building a structure almost 3 kilometres long in water 65 metres deep was almost the least of the engineering challenges of bridging the Gulf of Corinth in Greece. The construction would cross one of the most active seismic fault lines in Europe. Defying disaster called for solutions inspired by fragrant Indian incense, the ring-pull in a soda can, a toboggan, a hammock, and some shiny steel chimneys.

Damn right 😅🤣😂 Top gear is my favorite of all time 😅
I grew up briefly knowing Mr Hammond in my teenage years in Shirley Solihull West Midlands . And he was a bit of an annoying person then as he is now.
I mean, the earthquake stuff is impressive and all, but my goodness, 4 months ahead of schedule?!
Now, that's amazing!
there was huge pressure by the goverment because they wanted to present the bridge before the opening ceremony of the olympics in 2004. they wanted the olympic flame to cross the bridge
That probably means fake budgets wasn’t allowed, or no one cared of keeping a budget.
That is truly marvelous
And now they are on a crisis.lol
i3 13, which is irrelevant
I love the demonstrations Hammond gives in his documentaries. Very easy to understand
mdo686 no but if something need to be explained correctly you have to start with the basics. Duh all of us now how it works but not why it works and it makes us wonder, how does this simple function apply to a beautifully engineered bridge.
Lol too easy at times
i'm well impressed! the greatest teacher's in the world are the ones who can provide easy to understand example.
The demonstration with the metal rods is nowhere near close to demonstrating the roots. And sure they will settle until the rods hit the bottom of the bucket. and if there were no bucket to hit he would keep sinking like before.
@mdo686 we are not all english
I am going to show this video to my structural design students, it is a great way to show them many concepts.
@SRV. 123 wow only $20 to move that huge roof that's crazy
SRV. 123 It’s Electromotive Force causes by the fixed magnets and the inductors coils resistance to the induced current being generated - it’s now exploited to maintain safety systems on total power loss without needing back-up power systems, Tesla use it as do most other hybrids to recharge the battery - it’s something unique to energy, it has to change state, it can’t just vanish, so now we use it to our advantage in many systems. Most retarding-force actions have now been exploited into ‘energy’ saving or regeneration systems.
May I ask, do you prepare for 10.0 and 11.0 Earthquakes which are coming and do you prepare for crustation and pole-shifts which on the pole-shift side of things has already started?. Just curious, because man in my eyes is simply unable to deal with the pending doom that is coming and that includes quakes and more importantly a crustation shift that is going to take most of you away, gone, bye bye.
Lucky students to have a cool teacher to watch such an amazing vid
SRV. 123 I enjoyed your explanations thank you.
Act 1: Stabilizing subsurface against liquification 00:00 - 12:49
Act 2: Preventing the towers from toppling 12:49 - 22:49
Act 3: 22:49 - 28:22
Act 4: 28:22 - 34:34
act 5: it collapses from something stupid, like humans walking in unison(militia, or just wind) happened before will happen again.
nothing against the video host, seems an proper fellow :)

"That is the feeling of engineering." So true! I feel I was never able to adequately explain the immense satisfaction in designing something, and later seeing it work as intended. I wish everyone could have that feeling at least once in their lives. As far as I'm concerned, there is nothing more human. Do you think a cow, dog, or cat ever had the feeling of engineering? Perhaps, I shall direct ppl to this vid next time I need to explain.
People say nature does not seem as wondrous after you learn how works. Those people are deeply mistaken. Knowing how this bridge works only adds to its (aesthetic) beauty. By knowing how it works, you touch the bridge not with your eyes, but with your mind, an incredibly deep connection.
A similar feeling occurs with software engineering. And with people recognising a song you wrote as good music. Or when the framing/timing of a photo transcends/reveals your subject in a new way. And when you lean a motorcycle to an extreme angle and power through a corner.
its not engineering but as a game designer whenever i create a system for a game of mine and seeing it actually fully function gives that satisfaction you're describing!
@Sunny Quackers I make music as well and it is nice to have someone appreciate it. To tell the truth, I've never had a bong hit. Art is best done when you've got a crystal clear mind. Send me some music, I'll bet it sounds great.
@Sunny Quackers Of course, I'm not drug free mind you. Endorphins and caffeine can go a long way.
@rats arsed no. Animals do not feel the way a human feels.
You can't derive this a posteriori not a priori.
Ive crossed this brigde multiple times when headed to my grandparents , when earthquakes hit , you dont feel anything , but when the wind blows it is scary crossing that bridge , ESPECIALLY in a bus ... Buses tend to come to a full stop and turn in an angle when winds are at their peak speeds that can scare people who arent used to it . I was a child when this was finished but the amount of joy this structure brought to all Greeks is insane . Firstly it really helped with travelfor people who for their own reasons do not want to touch boats and also it was one of the most spoken builds of its time so a lot of fame was brought to it even if the Olympics were to be held in Greece at the time .
well bridge engineers should have a bit of aeronautics to help prevent that kinda drag ..... I mean making 90 degree corners rounded helps .
Wow, they found a solution to pier pressure.
lol
nice 👍
Imao
Giving in?
peer ? lol
This video should be shown in engineering classes around the world.
True, considering that engineering is often about overcoming the limits set by nature.
considering how our world works, the most amazing feature of this bridge is the fact it was finished 4 months ahead of schedule, thats an achievement right there.
to me I'd be questioning who didnt do there job.... because nobody works faster for the same ammount of money...and that worry's me.. what it. what can, and how

If it wasn't for unix apple would have been gone a long time ago. Apple today is really thanks to Steve Jobs when he was as NextStep computing. The foundation of Apples programming was built on C language with NextStep commands added to the language forming Objective-C. The unix os coupled with apple is Darwin. MacOS X really is the reason for the success of Apple.

Mr. Hammond does a fantastic job in this excellent production. His demonstrations of the physical properties of this great looking bridge were the best I've seen since the halcyon days of PBS. ... and thank you for letting this 80 year old into the "spiral strips on vertical cylinders" secret. I've never seen an explanation for this feature before.
Sucks on the smallest Cog with that idiot . Im from Canada and refuse to watch it . Stupid stuff theyve done with American vehicles and .. its not entertaining at all just annoying
Hammond? sounds like the guy we worked for,,,,, but I know its not him cuz we do reactors not bridges..... welding is cheap fer bridges, the specialists get on average twice the wage
Such a good video, explaining the basic principles applied to the bridge so lucidly.
Bravo, Hammond !

This bridge is a small project compared to all the recent projects in China... But they talk about it like it is a miracle... lol
Western media is all about 'we are great, China is evil'.
@@jessechen2013 The media can be right sometimes, but no one is questioning the great engineers of China and their construction workers. Besides most countries consider China favorable. One of the things that make people question China and their leadership is how they make decisions around human rights. But mostly China's economic situation and their military might because that is what almost any leader cares about.
This is a very advanced bridge and you should not be looking down on it like that because it still took some absolute engineering geniuses to make this happen. People worked hard on it, the engineers and construction workers, etc deserves some respect.
@@jessechen2013 that's simply untrue. Everything you said is just incorrect.
It sounds like the only western media you've seen is from Chinese propaganda TV.
@@jessechen2013 really so China just copies everyone else's stuff
It's not the size it's the purpose it serves
Let's face it how many Chinese projects fail esp dams
Take the dams that prevent fish migrating up river and now extinct
Amazing engineering AND presentation. Thank you Richard Hammond. As a builder I fully appreciate this.
Proud to work on that bridge. Literally on top of it for a few weeks! Hammond went down to the bottom, but he didn't use the shitty elevator to go up. That is an amazing experience. I miss the city where I grew up, soon I am visiting for vacation!
I don't know if it's his presenting style or careful selection of projects he chooses to be a part of, but any Hammond playlist almost invariably proves to be wall-to-wall win. Huge fan of this not-so-huge man.
While Hammond plays "tongue in cheek" quite well, the viewer is never made to believe that anything has been 'dumbed down' or that they are being patronized. Quite well done.
He's such a remarkable engineer explaining everything so nicely through demonstrations ❤
It really is a beautiful structure. And the way it integrates into its surrounding environment is astonishing.
Wonderful bridge.. wonderfully engineered 👏💐
I work on seismic dampers, bridge bearings and expansion joints. Thank you very much for sharing such a great video.
I’m so glad that this man is alive, I really am.
24:41 the editing and that evil laugh made it so more intense haha
I was like “hey that sounds like hammond! How funny! OH IT IS HAMMOND”
I didn't realise it was him until 10 minutes into the video.
How can you not realized it? The title clearly have his name
That is a magnificently-marvelous and beautiful bridge of exceptional engineering. I hope to see it someday.
I've passed it so many times! It's the crown glory of modern engineering. Greek engineering did it again.
Funny to think that I live less than 10 Km away from that bridge! The most impresive think is how massive it is. And I can still remember the fireworks on the 2004 Olimpics
Do you live on the North or South side?
Greek engineering at its finest since the building of the ancient temple of Parthenon in Acropolis in Athens.
This is THE most technologically advanced masterpiece, the wonder of engineering.
Με την διαφορά ότι το έργο το ανέλαβε η γαλλική εταιρία Vinci και όχι ελληνική, καλό είναι να κάνετε μια έρευνα πριν γράψετε.
You explained everything awesomely.Great Explaination.
Except who paid for it all!
Man, I remember watching this show like 10 years ago. How time flies
I love these kind of documentaries, nothing beats a practical demonstation for tricky to explain engineering and physics principles.
I remember looking at a hundred different diagrams on how the profile of a wing generates lift and I just couldnt get my head round it.
A mate of mine explained it to me at the pub with a packet of peanuts as a prop. That simple demonstration just made it click.
The fact that an earthquake just happened here in patras and youtube just suggested this video to me is a bit suspicious 😂😂
There is a conspiracy theory that certain governments have developed technology to cause earthquakes but personally I think these powers will always be in the hands of God.
@@BDMEDIAUK if you detonate a nuclear warhead in a certain depth underground you can cause artificial earthquake. The reason is that the explosion will release already loaded friction between tectonic plates for example and the explosion is just a trigger of something way bigger
@@BDMEDIAUK
It's tectonics. Nothing to do with a god (or a tooth fairy).
@Mike Oxlong you do not have videos, so you seem to only make comments
@Mike Oxlong you have no videos, we do not need you here. leave, eh
I love how he went to such lengths to basically say that the “viscous dampers” on the bridge are just a giant version of a cars shock absorbers
He has made car references before on this show, its just people may not exactly know just how a shock absorber works
Maybe because he is also a car enthusiast? It’s understandable when someone talks about things they love and passionate about
and when they fail, with neglect of changing LOL. oh right, "london bridge is falling down, falling down........"
I visit in the past the earthquake-proof bidge. It is an amazing experience! Photographically speaking the views are outstanding, the bridge totally looks like an arch from the sides...an amazing engineering miracle. A Hollywood film would be a nice tribute for this bridge!
The marriage of James may, Jeremy Clarkson, and this guy... was the best idea any TV company ever came up with
Amazing... and I bet there is some serious and expensive ongoing maintenance for this bridge.
Yup did you see the water at the bottom and that must be pumped out
Thank you Richard Hammond for showing to the world our beautiful bridge !!!! A Greek fan of yours !!!!
You do realize someone stole this documentary and there is 0% chance of this gnome reading the comics?
After working so many documentaries describing engineering marvels, I believe Hammond himself has turned into a half engineer.
Hammond makes this already interesting subject into something fun and interesting. Kudos to Hammond! Sub'd & Voted.

20:30 Thanks Hammond! :D Now I know what I will use as the base when i build my own house :D
It could survive an earthquake... but what about a hurricane or a tornado
Why are you building an house on a sea in an active earthquake zone ?
@@shahilashraf9755 that's a good question 😂😂😂😂
So the bridge is basically a Huge hammock with brakes. Absolutely genius, one of my favourite documentaries.
I really appreciate the experiements. Helps a lot in visualization. Thank you for this!
It's so nice to hear something for your country and it's not a bad thing once in awhile
Luv these docs. Bit old since bridge was done in 2004 but concept was interesting cause that place is highly active. Greece like Japan can get some of the worst earth quakes. Been there and drove on the bridge while on vacay it was awesome to see. Nice views the entire road way. Now they are building a new road to Patras from Athens with many long tunnels. Greece is mountainous.
I remember I seen way before I knew top gear was, and I thought Richard Hammond was just an ordinary dude but no, he's more than just a legend!
Aren't we lucky that some humans are more clever than most of us?
Just watched this documentary for a school project and enjoyed learning all about this amazing bridge! Add Richard Hammond, and it's 11/10
So this is quite interesting for me. I work in excavation. Digging foundations for multi million dollar mansions high in the mountains.. they run into the same foundation problems.. using micropiles to stabilize the ground beneath the home.. laying gravel underneath the foundations.. and surprisingly enough .we use dampeners on our tilt deck trailers. Funny how this tech is applied everywhere
These simple engineering explanations makes its so interesting to watch.
They should consider alien's attack as possible threat to the bridge
Possible... but not likely...
there's no need, because aliens only attack US of Merica.
@@ivrgn1720 😂😂
I suggest turbolasers turrets mounted on the top and sides of the pillars
Or migrants
Excellent job for both - bridge engineers and author of this video. Bravo.
This is not only very practical but it's a beautiful bridge. I would almost consider it art but purists of art would say it can't have any practical function to qualify as art. Well it still art as I follow a different definition. The best art is practical. Earthquake resistant yes, but not earthquake proof. There is no such thing as earthquake proof.
13€ in every pass. -_-
Bravo Hammond!. Excellent video. I've seen one or two docs before but his explanation is fantastic. I passed this bridge two or three times before and again next year. I will more fascinated now that I know all the engineering facts.
When I opened youtube this morning. I wasn't expecting to watch a hour documentary on a bridge.. but I'm glad I did! Now on to Fail army haha
A prove that Engineers are just amazing🎀❤
Brilliant documentary. I wonder how they replaced the fuses in the dampers after an earthquake? Thanks for uploading.
it seemed like it was just a bracket, so not like a tube shaped "electrical fuse" within the dampeners, but a doughnut shaped ring around them holding them back from moving until a desired force is reached. So replacement I would assume is just bolting them back on.
But can it protect against the most destructive force on all bridges... Road rage at 5PM?
I don't think God could do that.
Imagine if a Karen and a Kyle are in the same car.
Amazing engineering. Hammond also made it super easy to understand with his simple demonstrations.
That was a great explanation and a great piece of engineering.
First thing on my mind as far as Jeremy is concerned, "you blitering idiots"...
even with all the engineering, I'd still call the bridge "earthquake resistant" rather than EQ proof...
There is no such thing as EQ proof. They can only tell it will resist upto 7.4 or something. There is no known limit to the size of an EQ so saying anything is EQ proof is a lie.
The same thing goes for "bullet proof" nothing is really bullet proof. they are rated for specific size bullets. So those are also Bullet Resistant.
You're right, eq proof is not that scientific but that's kinda ok for a documentary in this level.
But "practically earthquake proof" isn't rigorously "earthquake proof", right?
You likely don't live in an earthquake prone region of the world -- and frankly, you're lucky if that's the case! Greece experiences a heck a lot of earthquakes every day, and every so often we get really big ones. There really is nothing as EQ "proof", only resistant. Nothing can completely negate the power of these quakes and the best you can do is get as resistant as you can and pray.
Defo nothing is a 100% earthquake proof so yes "resistant" would be a far better accurate description.
A reminder to all the haters (mainly germans),
Mechanics, Physics, Architecture & Mathematics are all GREEK words.
Great video, friend! There are times when nothing better illuminates your path than a burning bridge. Enjoy your travels and good mood!
Something they didn't that they didn't mention here is that the coasts themselves moves apart about 3mm every year. So they had to take that into account as well!
Lovely and extremely educational video. Fun to watch too; thanks for sharing.
It’s amazing that bridge ❤️🇬🇷
What gorgeous piece of engineering art!
Many, many years ago - when I bothered with aftershave, my favourite was Vetiver de Puig. 40 years on, I suspect that is where the scent came from: Vetiver Grass.
I hope I had a science teacher like him in school, very informative and simple explanation.
The bridge and the view in the area around the bridge is amazing. The documentary is very informative. The only sad thing about this bridge is that in order to pass the bridge with a car you need to pay 13.5 euros and additional 13.5 for the return trip. I think that the price of 27 euros for a round trip across those 6 Km is extremely high.
Welcome to capitalism
I’m at university for mechanical engineering right now and your videos are amazing bc they remind me why I love engineering and actually apply things I’m learning about in class

I got directed here after watching James May random questions videos. I had to stop, I drank a full pot of coffee and 2 cups of Barry's Irish breakfast and I'm falling asleep.
Excellent demonstrations.. Your efforts are highly commendable..Thanks a lot Sir!!!!
What an incredible structure! Its also absolutely beautiful 😍
The moment the engineer says at 42:30 "Yes, yes, it's an unbelievable feeling. This is the feeling of engineering." The looks on his face also says his very happy and amazed with the profession he has
Btw, I'm on my 2nd year studying civil engineering major in structural and this documentary made me love the course more and feel more privilege to study the field
Its 4:39 am. I need to sleep, but this is so interesting/entertaining.
The incredible engineering technology that went into the building of this bridge should make it one of the greatest wonders of the world.
Great job Mr
This is really good and
Educational
Awesome as always.... Great great great video
I live in an area expecting a major earthquake... finally have the ability to buy land and build my dream home. Earthquake foundations/basements are of intense interest to me right now.
celebrating engineers - a job well done
The French engineers did a good job.
I LOVE these documentaries with Richard!
They missed a good opportunity to compare the circular rods to airplane wings. This very problem, vortex shedding, is why airplane wings are smoothed to the flat edge at their back. Of course this wouldn't work for chimneys or cables because the wind changes direction, unlike with an airplane wing (mostly). However, at the *tips* of airplane wings, where the top and bottom airflows meet, the wingtips *do* experience vortex generation, and the vortices there generate drag. The solution is, essentially and ignoring some details, the same: add a wingtip that interferes with the vortex swirling back over the wing, more or less the same as the strakes on the chimneys.
All around fascinating bridge engineering and presentation engineering alike.
No you are just reaching to something that you understand most people dont grasp the structural make up of a fucking airplane wing who gives a fuck lol. Hes trying to explain it to be understandable by a child damn near. Not make it complicated by comparing it to something else that you have to explain also.... you have a hour not 2 or 3 in a TV show with commercials more like 42min
Aerospace engineer here.
I won't get into all the details because that would be a lot of typing, but wing tips or winglets in aircraft wings are not quite the same. It's a different effect that causes wingtip vortices.
edit: And the vortices that form are long stable 'tubes', whereas vortex shedding creates an almost turbulent 'twirling' wake.
Airplane wings shape have nothing to do with vortex shedding at all. A wing is shaped like that only to make air travel faster underneath then above, thereby creating lift. Your comment just shows you don't understand anything about aerodynamics
Neither do the replyers above me. Engineers are dumb as fack. Machinists make the world go round
Just watched: this feat of engineering is inspirational to say the least! Wonderous!
Much more interesting than Top gears
like to see more please
Damn that’s one hell of an engineering feat
