Question

Which of the following is true about intermediate length compression members?

(a) members will fail by yielding only

(b) members will fail by both yielding and buckling

(c) their behaviour is elastic

(d) all fibres of the members will be elastic during failure

The question was asked during a job interview.

This question is from Behaviour of Compression Members & Types of Sections topic in portion Design of Compression Members of Design of Steel Structures

Answer 1

Correct choice is (b) members will fail by both yielding and buckling

The best I can explain: For intermediate length compression members, some fibres would have yielded and some fibres will still be elastic. They will fail by both yielding and buckling and their behaviour is said to be inelastic.
