Question

The shear capacity of web comprises of strength

(a) before onset of buckling strength only

(b) post buckling strength only

(c) before onset of buckling strength and post buckling strength

(d) compression strength

I got this question in an interview.

I want to ask this question from Web Panel Subjected to Shear topic in chapter Gantry Girders, Design of Plate Girders & Industrial Buildings of Design of Steel Structures

Answer 1

Right option is (c) before onset of buckling strength and post buckling strength

The explanation is: The shear capacity of web comprises of strength before onset of buckling strength and post buckling strength. strength before onset of buckling is contributed because of elastic behaviour wherein stresses are entirely elastic and the only requirement for the stiffeners is to keep the web flat.
