MashaAllah.Absolutely the best series on steel structures
JazakumAllah

[@user-fm7ru3kr5j]

Thank you very much

[@ahmedmatrod4764]

Thank you very much Doctor for this explain really this video and video no. 14-1,14-3 about beam make me understand this subject

[@dr.mohamednoureldin5718]

Happy to hear that

[@scaldor]

Such a great learning...... I am so thankful to you.

[@user-mu2ee2de9c]

Thank you so much

[@mumtazali2845]

Great sir.
Thank you.

[@Shahab087]

Good job

[@waleedzafar5558]

Thank you so much sir
one request sir please make a video on understanding of the manual

[@haseeburrehman4352]

Very helpful sir

[@mohamedmaher87]

very nice one

[@sharifulislam2569]

Nice Lecture

[@spandhanaharidas]

Sir, Can you do one lecture on base isolation, isolators, and properties, design of isolator system, design of isolators, design of the isolated building

[@thaileangtouch6811]

Thanks for the great tutorial, Dr. Mohamed. I think this may be a matter of duplicating (or copy-paste), but I would like to point out that the classification of shapes should be as follows?
λ ≤ λp (cross-sectional shape is classified as compact)
λp < λ ≤ λr ( the shape is noncompact)
λ > λr ( the shape is slender).
Correct me if I am wrong. Thank you.

[@dr.mohamednoureldin5718]

Thanks Thaileang, You are right, I added the correction in the description.

[@sasi74]

@@dr.mohamednoureldin5718 is the equation nd formula is not sir?

[@engahmedsalah]

great job, thank you! May I know what software you're using for your notations and handwriting? is it included in the screen recording software? what's the name of it?

[@m.shaihanayub7179]

Why yield moment is not the limit state and plastic moment is..?

[@haseeburrehman4352]

Sir kindly upload steel bridge design lectures

[@engahmedsalah]

I believe that rts should be squared

[@sabbursardar6266]

What should i do if Mn>Mp ??

[@rceby2024]

I think it is in the elastic region? Because since Mn is less than Mp, it probably is within the elastic range, still not reaching the maximum capacity of the steel which is Mp. I assume that you will still have to apply formulas related to yield moments
