Hi Brendan, Thank you very much for this great summary on FEA. As you seem very familiar with the method, that would be interesting to have your thought about how you model complex phenomenom like imposed deformations in reinforced concrete structures (like temperature changes or shrinkage). Thanks again for your work.

Great video Brendan. I would only want to add that what could be a great follow up to this video, in my opinion as a recent graduate, would be one in which you talk about and give some pointers on how to learn, what to learn and the extent of what one has to learn with respect to FEA. Otherwise great content, cheers.

I agree, 3D FEA is so complicated. It is hard to verify if your results are correct. Also, its analysis time increases as your mesh size decreases. If you are using Abaqus, the modelling itself takes considerable time since you have to model the parts one by one then assemble them. Ansys is more a user friendly than Abaqus but also requires experience and time for the analysis.

Thank you

Thanks Brendan. I’m an engineer in Scotland. Maybe will complete some projects in Australia with my organisation. One bit of feedback. ‘Lets get into it’ followed by ‘before we get into it’ comes across as slightly counterintuitive in scripting / structure. Other than that. Great video.

Not sure how eurocode works. But, ACI 318 recommends reducing the moment of inertia for the cracked section, instead of Young’s modulus. I suppose it’s all the same though, since Young’s modulus and moment of inertia both carry the same weight in the stiffness matrix. What a great video. I don’t think anyone learns FEA in one semester. FEA is a lifetime of learning. Keeps us from getting bored as our careers progress.

Hi Ryan, for a plated model it is harder to reduce the moment of inertia as it is a geometry governed. The only difference youngs modulus would be axial shortening.

@@BrendanHasty This is great to hear a reply, thank you! I realize now that we should reduce Young’s Modulus for Plate and Shell elements; in order to maintain correct geometry. It is up to the designer whether to reduce E or I for beam/column elements, based on what they’re checking? I remember now that rod elements only include E and A in the stiffness matrix.

@@ryanharris6090 some FEA programs, such as Oasys GSA (disclaimer: I work for them) also allow you to independently adjust the in-plane and bending stiffness relative to the geometric properties so that you can address such problems.

I would argue that 2D elements are actually harder to work with, although they more easily give rotation information. With 3D elements, you will find many more singularities in you model, which are actually physically there. With 2D elements, these are glossed over. Do you compare a lot with actual strength and fatigue tests?

Do you teach structural modeling/software analysis in your pattern ?

Lol FEA might be the forever sorrow and bitterness deep down in my heart. This was the only unit I was so keen to learn but failed at Monash due to unbalanced workload from a team project in another unit. And when I got another chance to re-study the FEA at UniMelb, man, the final exam was changed. There were FEA questions and structural design questions and the latter is indeed design oreineted, which means, for example, I had to trial concrete cross section and correct it if the selected cross section fails in capacity calculation and so we needed more time. We had no choice but to give up FEA since we could not guess how many marks we can get from calculation steps for FEA. But we definitely know we can get the most marks as long as a complete capacity calculation is performed in structural design 😂. So to myself, I could never prove that I comprehended FEA and this is such a pity. But anyway, thanks for your great video.

dudee sameee. I was so eager to learn FEA to this day but when I took the class a lot of things happened in my life outside of my control I ended up just copying and memorizing past problems and solutions, which in the end gave me 0 understanding on the concept. Plus I also forgot how to do the hand calculation so I guess I need to re-learn it from youtube or FEA courses somewhere :"")

Hi Brendan, I have a qus. for you ... why when we check defliction of steel beam we check it for live load only ?? & thanks for your videos ❤

@BrendanHasty

2 жыл бұрын

Hi Mahmoud, it's because you can typically pre-camber out the dead load deflection hence live load is more critical. But you shouldn't pre-camber out any more than 80%, but if you pre-camber floor beams, it can lead to a bouncy floor.

could you use more specific about linear and non-linear analysis please?

It is interesting to see FEA from a civil engineers perspective. The GLAD acronym does not at all address the most difficult part of FEA which is establishing the correct boundary conditions. For example, the conrod animation indicates clearly that the boundary conditions are wrong. One end (the right) was fixed while the other end (left) appears as though a pressure load was applied. I have seen this mistake so many times. This is why civil FEA engineers should leave mechanical systems to mechanical FEA engineers.
