excellent professor, explain too clear 👍

Very good lecture, keep it up!

Cant be explained better,Thanks.

Hello. Thank you very much for your explanation. It was awesome. Can you give more examples? And I hope you will continue to explain the advanced Reinforced Concret. Good luck.

David thank you for the great presentation. Could you please share the pdf with the lecture notes?

Thanks David

Sir please share these lectures with us in Pdf Or Ppt format.. i will be very thankful to you... Thanks for these lectures btw

Thank you Sir for your excellent lecture. May I during bar detailing does it matter that the horizontal bars are given at N2 layer instead of vertical bars or vice versa? Could you please explain why that does matter?

Did anyone ever got the spreadsheet for calculating the neutral axis?

Thank you professor, can you create videos about Analyzing Timber?

Hi prof 👨‍🏫, could you make a video for design stud rail for punching shear?

can u please share these lecture

can u make a video about design shearwall foundation :D

Dear Sir, do you know how to determine the side reinforcement for raft foundation? Thank you

to calculate shear rigidity using your formula shown, does your E mean shear modulus? Under what circumstance, would you include flexural stiffness when calculating wall rigidity? Should you ignore based on aspect ratio or it is negligible. Can you further explain a bit behind the concept.

E = Modulus of Elasticity G = Shear modulus so its not shear modulus :)

Kindly check vn≤0.66 sqrt(FC'') AC. Not 8 .......

At 32:20, why is that the shear rigidity is EA/L instead of EI/L where I = h*lw^3/12??? Appreciate if someone could enlighten me...thank you.

I don't know whether you've figured it out by now, but I just watched the video today. I believe that for this example EA/L is correct since David is making the assumption that ONLY walls contribute to the lateral system, and since all of the walls have the same thickness (in this example) you can calculate the center of rigidity just by comparing the lengths of each wall.

Please, I need to this file

You know better than me that ACI-318-2019 says that we should amplify shear force for designing special shear walls. In the commentary, ACI-318 mentions to NZS 3101 code too. NZS-3101 and EUROCODE say for such an approach the PHI=(strength reduction factor ) is equal to 1 .... phi=1 instead of 0.75 or 0.60 Why is it different in the two codes? I send some document photos-(forgive me). and please guide me. thanks before.

very good please can you send me pdf file
