torsional analysis 1

[tabio]

I am what today may be considered an "old" engineer, maybe outdated.... I want to go back to the basics of engineering and want to review/update my knowledge of torsional analysis.

I tried for the first time in more than 20 years to check the design of a connection including torsional analysis, and I have to confess... I got scared of terms among others, such as "pure torsional shear", "warping shear" and "warping normal shear". Not to tell you about the constants in greek letters...

My real question is: Where in the

I find courses teaching/reviewing the torsional basics?

My short experience has tought me that "ignorance is daring..."

AISC has an excellent Torsional shear design guid, I think it is number 13 (?). Go to

http://www.aisc.org

and shall find it on there. It sells cheap compared to other text books. Also the AISC engineering journal has several articles that deals with torsion.

A statics text book will be another good start. Torsion is not that hard to work with if yoou understand it, have the math tools and well defined boundary conditions.

Good luck

Check out T-117 Pub from AISC on how to calculate torsion on open sections. Closed sections like tubes and pipes are OK. But wide flanges, channels, angles, etc. are tough. What's even tougher is once you get the warping and normal stresses, what do you do with them? STAAD has a good chapter on torsional analysis in their online manual at
