Question

The crippling strength of web at supports is given by

(a) Fcrip = (b+n1)fyw

(b) Fcrip = (b+n1) t

(c) Fcrip = (b+n1)/fywt

(d) Fcrip = (b+n1)fywt

I had been asked this question in homework.

My query is from Web Buckling & Crippling topic in section Design of Beams of Design of Steel Structures

Answer 1

Correct option is (d) Fcrip = (b+n1)fywt

To explain I would say: The crippling strength of web at supports is given by Fcrip = (b+n1)fywt, where b+n1 is length obtained by dispersion through flange, t is thickness of web, fyw is design yield strength of web.
