Excellent work and thank you. Could please tell me where to refer in EC3 to find the A eff (effective Area) & W el eff ,W pl eff (effective section modulus) and reduction factors (Rua1 Rua2). I suspect they are in GF( Ground Force) in Note 7 but I have not been able to find them ! Thank You !
hello thank you for your great efforts. I have 2 questions please..firstly why the Fyield and Fultimate values decrease as the nominal thickness increases ? secondly if we assume that we have 2 sections having the same thickness and flange width but different steel grades that means if we are going to classify this member it will have different classification depending upon the yield strength of steel how is that possible?
Amr Abdullah 1) Mechanical properties of steel are influenced by chemical composition, heat treatment and manufacturing processes etc. Thinner sections through relatively more mechanical working compared to thicker sections gains different properties (increase in strength). 2) Cross-section classification in Eurocode 3 is based on the ‘material yield strength’, the width to thickness ratios of the individual compression parts and the loading arrangement. Furthermore, the cross-section classification limits are based on the assumption that the cross-section is stressed to yield (except some relaxations).
@@IamDilakshana Thicker parts have less reduction ratio while Thinner parts have higher reduction ratio. General reduction ratio is 1/6 which means if plate is converted from 36mm hot billet to make it 6mm then its reduction ratio is 6. As the reduction ratio increases the Work hardening in material causes Yield strength to go high. I hope it answers your Query Abdullah. :)
can i ask u one question? Do u know where to download steel design Eurocode 3 book file in english version? I only have in french version and it is hard for me.to understand since im not good in french. Thank you
Hi , i have a question If in the. Exam ask me to design , so at the beginning there is way to choose a satisfy section before start solving the question?
Hi. You can choose a suitable section by undertaking a preliminary design and then verify the section during your detailed design (solution). However, in an exam you have limited time to take that approach. Do you have a model question or an example? علي مدن
Thank you . I hope you continue make videos about eurocode
Thank you so much for making it easy to understand :)
You’re welcome 😀
Louise, this is very helpful. Thank you very much!
Any examples for circular hollow section class 4
For Table 5.2 sheet 1, part subjected to bending and compression when a>0.5 what that sign alpha stands for and how do you find it?
I have a question in example 1: why you dont calculate the class of the web under compression to find the classification ?
Hello why did you neglect the web check under compression thanks because it would change the overall class to 4, thanks
small correction
16:53 - 72 x Epsilon = 66.24 Class 1 (Not 66.56)

Rahman Rahmani Apologies for the slow reply. Did you manage to find what you were looking for?
@@IamDilakshana Thank you for your reply. Unfortunately, I have not found it. You could send me a link. Thank you!
Thank you for this video :)
My pleasure :)

Dilakshana Mayadunne yes i have , but where can i show it to you?
علي مدن facebook.com/IamDilakshana
علي مدن I can’t message you on Facebook for some reason. What ULS checks are you expected to undertake?
Hi, could you make a video in which you show us how to do the cross section classification in Tekla Tedds ?
Good explanation
Keep watching!
how do we know if is class 1 2 3 4?
Thanks a lot!!!
good presentation
ALLI GODFREY 🙏🏻
The most difficult thing for me 2 nights haven’t slept
Anyone for making me understand online
Thanks a lot
But I am looking for aluminium code
I'm sure this is a good lecture, unfortunately I couldn't understand the lady's accent.
