Question

The function of bearing stiffener is to

(a) improve buckling strength of web

(b) preclude any crushing of web

(c) restrain against torsional effects

(d) increase buckling resistance of web

This question was addressed to me in an interview.

This is a very interesting question from Stiffeners in portion Gantry Girders, Design of Plate Girders & Industrial Buildings of Design of Steel Structures

Answer 1

Correct choice is (b) preclude any crushing of web

To explain I would say: The function of bearing stiffener is to preclude any crushing of web at locations of heavy concentrated loads. Thus, they transfer heavy reactions or concentrated loads to the full depth of web. They are placed in pairs on the web of plate girders at unframed girder ends and where required for concentrated loads.
