Question

Which of the following is true?

(a) web crippling is buckling of web caused by compressive force delivered through flange

(b) web crippling is buckling of flange caused by compressive force delivered through web

(c) web crippling is buckling of web caused by tensile force delivered through flange

(d) web crippling is buckling of flange caused by tensile force delivered through web

The question was posed to me by my college director while I was bunking the class.

My question is taken from Web Buckling & Crippling in portion Design of Beams of Design of Steel Structures

Answer 1

Correct choice is (a) web crippling is buckling of web caused by compressive force delivered through flange

To explain: Web crippling is buckling of web caused by compressive force delivered through flange. To keep bearing stresses within permissible limits, the concentrated load should be transferred from flanges to web on sufficiently large bearing areas.
