Steel I-Beam Web Crippling - When to check
Steel I-Beam Web Crippling - When to check
(OP)
I had an interesting question the other day from a PHD engineer: Design a steel beam.
Sounds simple enough.
My approach is to check the section class (web thickness to depth ratios), check the moment capacity of the section, Shear, member strength, deflections - and you're done, on to connections. He mentioned that I missed out web crippling. My view is that if you have a member where the governing force is the moment, that crippling of the web (unless it's a slender web) is unlikely. It is only when shear becomes the governing force that crippling may occur and should be checked.
What are the thoughts on this?

Very rare to have web crippling. Perhaps in very short beams with large point forces and large shear at supports, would check for web crippling and buckling.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
