Good Information. Do you have any videos on derivation of stiffness matrix including 7th Degree of freedom ?

Thanks for the question! So far, no video, only this document on my website: civil-terje.sites.olt.ubc.ca/files/2020/03/Frame-Elements-in-Torsion.pdf

Thanks a lot. Sir, can you recommend a book or resources for further reference.

Thank you very much for the question. The references that I use most myself, are printed texts in Norwegian, created by instructors of courses I took back there. Beyond that, one would normally recommend several of the seminal textbooks written by Timoshenko and various co-authors. However, specifically for warping torsion, it might be best to go elsewhere, and then I am reluctant to recommend any specific book. However, when you search, keep in mind that books on ship structural analysis and design often have excellent sections on warping torsion.

@@terjehaukaas Thank you for timely response. Very glad to hear from you. I plan to see more of your videos. The one on warping torsion is excellent. High quality online resources like yours are rare to find. I would request you to upload more such videos. Do you conduct any online course?

@@inaamqazi Thanks! At present, I do not conduct online courses, but that is a new idea that perhaps I should think about. For now, I do all my teaching in the classroom at the University of BC in Vancouver, Canada.

Ehi Prof, thank you very much for the free content and very high quality, it's rare to find information like this for civil engineering. I have one question: how can I derive why some geometries do not experience warp? Thank you very much :)

Thank you very much for the nice comment. I can think of two ways of verifying that certain cross-sections do not warp. One is experimental, simply building plastic beams and twisting them to observe whether the cross-sections warp. Another approach, probably more along the lines you had in mind, is to draw the omega diagram for all kinds of cross-sections. Then you will observe that for certain cross-sections, such as X and T cross-sections, the final omega diagram is zero all over. That means they don't warp.
