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.

Thank you for the very nice comment, which entertains me, because I have second-thoughts about using that Google AI voice. :) I appreciate your feedback!

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.

@@terjehaukaas Thank you very much for the exhaustive response, keep up with the wonderful work :)

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

@@terjehaukaas The document would be the same for euler and timoshenko beam right?

Send me an email to terje@civil.ubc.ca and we can discuss.

Thank you very much for your contributions

Thank you very much for the nice comments. All the Python code you seek is posted at terje.civil.ubc.ca/finite-elements. You will find the Python code for solid cross-sections there, and elsewhere on the page you will find the other required functions too, which you simply place in a file called terjesfunctions. Please do not hesitate to ask follow-up questions.

@@terjehaukaas "When I run the Solid Cross-section Analysis code, it asks for the 'terjesfunctions' functions. Is it possible for you to indicate where I can find them?

@@terjehaukaas When I run the Python code, it gives me this message: ModuleNotFoundError: No module named 'terjesfunctions'."

@@terjehaukaas I am very interested in all the topics on your channel, and you explain them very well. Thank you very much.

The Program is RT

This program is called Rt and is available at www.inrisk.ubc.ca.

Terje Haukaas thanks i installed it but i cant figure it out how to give inputs

Sharailin Gidon Have a look at the other RUclips tutorials posted at www.inrisk.ubc.ca. :)

Terje Haukaas Thank you so much for your great help sir :)
