The best video I've seen. It's amazing how clearly you explain it all. Thank you, Mat!
Great video, Mat. I appreciate the quality content and great explanations. Keep up the awesome videos!
Thanks a lot for explaining the structural design workflow in awesome way 😃
Great video. In practice, analysis and design is iterative and will happen at the same time as the drawings, especially because the architect and other folks need to coordinate their drawings with ours as their design developes.
Great job Matt. Good to see you doing well.
This video was absolutely amazing to watch. I learned a lot, thanks Mat!
Thank you Mat, would appreciate that you can keep on continuing on releasing the technical video like this.
More to come!
i was in a parking garage under a building today and was wondering how everything stood up! thank you!
Thank you for this video. Very informative and helpful for those with anxiety about staying in tall buildings
Thanks Mat, this is good. I am a technician for structural engineers (the drawing part in your video) and I was always curious about what they do before I am involved in the projects. this gives me the answer!
Zoe, glad it was helpful!
Wow, thank you for making and sharing this video, it's very helpful and informative.
Amazing, i'm gonna be studying architecture in the fall so this is all very important for me to learn early.
Thank you sir. Keep making these type of videos about teaching aspects of construction.
Another excellent video! Nice work, Mat.
Bookmarking this one to show to my friends what structural engineering is all about.
Thanks Alex, hope you're doing well and Happy New Year!
best video ever, I am in my 5th year as a Civil Engineering student and this video could have come in handy in my early years. good video 😄😄😄👍👍
Glad you enjoyed it! Best of luck!
THANK you for your videos
I would like to become a structural engineering but i dont know what school To go
@@MatPicardal hello could you referme a school where i can go To learn to be a structural enginer please
@@MatPicardal I learn civil engineering in my country but i would love to come To us to study
This is really incredible. Thank you so much and please try to give us, this type of video.
This video is very informative. As a Civil Structural Engineering student, It really showed what I've learned and people actually use those methods to design the structure. Thank you!
Thanks for the comment Aden! Glad it helps.
Thank you, really interesting and useful for work
This video tells us that structural engineering works in three fields Analysis, Design, and Drawing So it's better to learn each software from all those fields thanks mat for the wonderful video.
As A Civil Engineering student at my 5th year, This 10 mins video about Structural engineering was more informative and constructive..
Thank you for those interesting informations .
Thanks for representing us here on RUclips, Mat!
Great video, Mat!
great video air I really appreciate your work
this video is really cool
waiting for more sir
Excellent Presentation!
Good information sir,, 😊👍
The most important part in all this process is the drawing part. It really does reflect all the info you got out from the design and in some extent, it can provide some insight and make you cuestion if you are designing something good or bad.
How do you define important
@@BigDripper1of1 all the considerations you took in the analysis and design of the elements should be reflected in your drawing plans. For example, in a steel structure you consider that in your base plate, it will be a pinned support when designing it on whatever application you use for, but in your drawing plans you specify and draw it as a moment connection is something that can't happen in this case. One may think that's impossible to make such mistakes, but in reality that's the hardest task of being an engineer.
Very true! If our designs don't make it on the drawings correctly, they will be constructed wrong and our analysis goes to waste, not to mention the building may be built incorrectly with regards to the engineer's intent.
Useful video with clear explanation which was easy for to understand. Any videos about how the wind load is performed..?
very clear and informative. Thank you for presenting this video.
Glad it was helpful!
Great job - as always Mat
Thanks again Jared!
This is a fantastic video to show to non-engineering people to explain what structural engineers do! I always have trouble explaining what engineers do to "lay-people" without rambling for an hour.
I do prefer the buildings that don't fall down, so thank you, structural engineers.
Excellent information
Great video!
wow, this is great and pretty new in YT! Can you talk, someday, about curved structures, like concrete shells? Because i think my formation lacks this type of thing. And how engineers (or what type of) study something like this
Uniqe video as usual keep it 💕up
Can you please make a video about buildings that combine Steel sections with Concrete
Great content ❤
Thanks Jamil!
Really good explanation here for the non-structural engineer, good job mate
Thanks for the feedback! Definitely helps.
i suggest a video series for English terminologies for fhe field of construction for foreign structural engineers
Master the concepts of practical civil engineering here ✌
Sir, can you please make a video about FRP/Fiber Reinforced Polymer as a material used in construction? Thankyou
Hi Mat, I think you forget the give and take between drafters and engineers during documentation and modelling.
This video answer my confusing Sir. Please can you make one for bridge for me. thank you, very informative video, and educational.
you're back collegue. in my studio i play in background "structural engineering podcast".
my collegue seriously think"ok....the boss is totally flip out". (in Italy, sadly english Is still a very foreing lenguage). but step by step, they love this "podcast time". now.... thumbs up and see de video. see you later
Thanks Paolo, yes, it's tough with work and balancing health and relationships, but I eventually make time!
Thankyou Sir
What software you recommend/use for structural engineering load estimation & simulations
Amazing video!
Thanks!
Love your videos ❤️❤️
Hey Mat! I'm a Structural Engineer on Brazil, do you know if it's possible or common to work remotely for a company overseas? If so, could you please make a video telling how does it work? Tyy
It's possible but I think it's more common for very large companies that have international offices. I don't know too much on that subject though, as I'm sure there's visa issues and what not. Might be easier to work as a contractor though, thinking of something like Fiverr.
Only thing I see missing is submittal reviews. For example, reviewing concrete mix design prior to concrete being ordered, or reviewing rebar shop drawings as the structural drawings don’t go into that crazy level of detail that shops do.
Hello Mat, nice an clear video, tell me what structural software do you use for analisis?, like the showing in the video
Hi Mat,
I want to know that which software have you been using for showing stress generation chart over the building plan?
Please answer my query
Hello mat
How to fix failure construction house?
If it impossible, how to dissamble 2nd floor house with manual technique?
I hope u can make a video for tips and tricks for reinforced concrete design and steel and timber design. Cause these 2, I'll be taking this coming 2nd semester hahahaha. Btw happy new year engineer!
You can start by refreshing what you know about strength of materials, statics and the courses of structural analysis. But I'll tell you to focus more on the part of strength of materials than anything else, it's very important to know this because all the theory used on explaining those 3 materials, uses a lot of information from strength of materials sometimes. Also try to always imagine or illustrate the situations when you begin the course, it helps a lot than just seeing a bunch of numbers and equations.
Thanks Miggy, been thinking about those!
4:30 in the case of seismic areas, the core building wall would be enough to resist an earthquake lateral force? BTW great channel. Just subscribed!
Thanks
Best video engineer
Thanks, I was wondering last night, what if it was a residential block and ALL the tenants place their heaviest loads on one corner of the building and left the other side empty. Won't it eventually slant and break if left for long periods?
Hey Mat, which software you use for your analysis?
thanks sir
Hi. I'm a Civil Engineering student. I was asking which software you were using to analyze the stress area in your building when exposed to lateral loads or gravitational loads on your slabs etc
ETABS for lateral loads, and RAM Concept for gravity. Other alternatives include RISA 3D and ADAPT.
@@MatPicardal you can write your own programs or develop your own software for analysis and design
Code stipulates you design for the most critical of
1 Gravity loads alone
2 Gravity + Wind loads
3 Gravity + Earthquake loads
Good bro
what is the best software in analyzing a building?
Sir, I just have a question that I hope you will notice,,, that I am just curious because of the tall buildings that reach 50 storeys above, how do the first floor pole of the building handle the 50 storey building above, , because the pole of the first floor carried all the weight of the building,,,
Sir i am completing bsc in civil Engineering. So what would be best.structure designer or a project engineer.
How long it takes to learn designing. Etabs,sapp,or how many app need.i am confused actually what to do.i really love mechnics of something. Is there any opportunity for me after my graduation for msc in usa.if there is then what's the process.
Listening you From Bangladesh 🇧🇩🇧🇩..
do you have any courses so that I can take it on undemy?
Sir, what do you think about the buildings thats collapse on turkey earthquake ?
Basic info but OK! For students
What causes the cracks around RC beam hollow areas
What is the official name of that building frame model @ 3:13? I always saw them but could never remember their name.
Mola Model. I made more videos demonstrating it with a discount link as well: ruclips.net/video/141Zmuw9Xcg/видео.html
Hey sir I think the loads from the slabs will be transfered to the beams first before into the columns? But anyway good explanation 👌🏻
No beams with flat plate
sir, big fan ❤🇧🇩
which software do you use?
Good day Engr. Paano ba maging isang licensed structural engineer dto sa pilipinas?
I'm curious to know what is included in an architect formation in the USA, I don't know if it is the same but the 1st phase of analysis that you mention doesn't work like that here in Italy! As an architecture student we are tought to design (roughly or so) the structure, even using structural engineering softwares like SAP, and THEN you go to an engineer to properly define the job. In this way you can keep everything under control, given that you won't have to apply massive changes for unespected issues. In the USA the architects don't have the structural responsability of a project and that's why or they simply "don't want to risk it"? Thanks whoever will answer!!
This is what architectural engineering is all about.
It doesn't cover the nitty gritty of structural engineering
The structural engineer has the final say on the safety and stability of the structure, not the architect or architectural engineer
@@festusajayi8917 so there's also another profession, I didn't know! I'll have to search what my course of studies translates into in the USA, seeing that it's like in the middle. Thank you for your answer!
How do you know that the ground isn't going to shift and the foundation isn't going fail? I've seen homes on the side of hills but how do you know the ground isn't going to shift and there will be a landslide? This is always my main concern. For buildings not on hills how can you guarantee that the ground is solid enough?
That’s a geo technical problem, the site would already be analysed by geotechnical engineers to get the bearing capacity and see whether the soil fill needs to be change and so on and so forth.
Not a structural problem
First rule Foundation, second rule foundation, third and final rule foundation PERIOD!!
The problem with nearly all designs is 1. Corruption. i.e. bribes, use of different materials by the builders/contractors, cutting corners. etc etc. 2. Miscommunication. 3. What's designed is rarely if ever translated to a build i.e. last minute changes, additions, subtractions etc etc. 4. Costs are ever increasing. 5. Last but not least is poor or incorrect design.
Overcome all of the above and the build might be completed to everyones satisfaction. But until then we will get more Surfsides.
Except WTC7 xD
In 7:07 , it’s mentioned loads will be transferred from slab to column (is it assumed that slab and beams are monolithically casted?)
In design of Flat Slab no drop beam. The load transfer from slab to column
I consider the word "slab" here as "floor", the vertical load spreading the tributory area is transferred to the column,
Yup, it's a two-way flat plate slab (no beams, slab is strong enough to transfer loads to the columns).
@@MatPicardal What is depicted in the video is a flat slab as distinct from a two way slab which is supported by beams on its 4 sides
Great
My brother you should have been there when certain engineers built certain multistory buildings with supporting beam structure so low quality that they melted from a fuel fire
Thank you for your video, iam in my 1st year as a civil engineering student. I want to be a structural Engineer🥺👷🏻♂️
Cool video can i have a favor can we get you as our respondent for our thesis can we interview you. Our topic si Earthquake proof we just need someone who are have the knowledge in earthquake proofing thank you ❤️
As Structural Engineer of many years experience (qualified before you were born I guess), I would point out that there's a conceptual phase way before the analysis phase. The ultimate success of the project is probably decided at this stage - have a good structural concept and it will be easy to design and build, have a bad concept and it will be a struggle until the end of the project. It's a big mistake to get involved in the analysis too early in the project cycle.
yes, I think he started with schematic phase directly in this video.
@@DeepakKrishna11 He skipped over the conceptual phase which is typical for young engineers. Too keen to resort to their computers
Quite right
The conceptual phase can also be referred to as a feasibility study phase or preliminary design phase
Check lists for analysis and design can be handy in this phase
Agreed. Feasibility is everything
@@festusajayi8917 The conventional sequence and terminology in some engineering sectors is feasibility studies / conceptual design / FEED (front end engineering design) / detailed design.
HNY Mat
What about foundation and soil analysis?
It is done by geotechnical engineer.
How commonly are you actually doing work by hand? I work for a Gc and find that after talking to most of the structural engineers, I’m doing more math than them just with takeoffs and basic form forces than they do in design. They’ve always told me they just use the computer
It depends what they are using to do the analysis. Some programs require the engineer to calc their own loads. Column and foundation loads are almost always hand calced. Quick design checks during CA are also often done by hand. It's all simple math.
How to meet the code for Americans with disabilities act of 1990, 504 section of rehabilitation Act of 1973, architecture barrier act of 1968 and fair housing Act?
Can you put braces in rcc buildings?
Everything is possible. But from where I am, it's not common
It's more common in steel structures
@@symonortega thanks
@@Joker-oh3lb there are some examples in Google images if you want more insight
For high rises in seismic zones, you can see steel braces being used as outriggers/support for the concrete cores. But usually not combined for most convential projects as it's generally more expensive to construct.
@@MatPicardal interesting
What is the go to software, you civil engineers use??
There's a lot out there, but ETABS, RISA, RAM Concept, ADAPT, Enercalc, SPColumn are just a few.
Very nice. How are engineers in the US deal with a risk of disproportional collapse? Here in the EU it can be tricky for the high-risk category buildings, because eurocodes give no direct guidance and require to do it well anyway.
Some high profile buildings require redundancy and alternate load paths, such as if one column fails, the other nearby columns can take the load. I have limited experience on it, but that's what I've seen done.
Do structural engineers need to take dynamics?
Not as simple and straight forward as he puts it
Before the advent of computers, analysis and design was undertaken manually
I recall a question a principal at a structural firm in Lagos Nigeria asked me. The moron spent more time trying to understand how I did the calculation than the duration of the interview.
Structure engineering vs architecture who is earn more money
You can be good in teaching.
Thank you Thor!
Can you make a video about shish kebab steps, please. Thanks
Guys i just wanna know why is architecture paid more than the structural engineer cz the engineer is the one who made his idea a real thing
Pls can anyone explain
Architects are not paid well. Often less than engineers. In the US.
@@michaelweyenberg6238 i see
I live in kenya
I always hear architecture are the ones who are paid more than the engineers
And i am like why the heck is that , cz when anything happens to the building engineers are at fault
This means they should be valued more as they are responsible for the structural part of it
