Question

The value of non-dimensional web slenderness ratio in the nominal shear strength equation according to simple post-critical method is given by

(a) √(fyw/(√3τcr,e))

(b) (fyw/(√3τcr,e))

(c) (fyw/(τcr,e))

(d) (fyw/(√3τcr,e))^2

This question was addressed to me in a national level competition.

My question comes from Web Panel Subjected to Shear in section Gantry Girders, Design of Plate Girders & Industrial Buildings of Design of Steel Structures

Answer 1

Right answer is (a) √(fyw/(√3τcr,e))

Explanation: The value of non-dimensional web slenderness ratio in the nominal shear strength equation according to simple post-critical method is given by λw =√(fyw/(√3τcr,e)), where fyw is yield strength of web, τcr,e is elastic critical shear stress of the web.
