Question

Which of the following is property of compression member?

(a) member must be sufficiently rigid to prevent general buckling

(b) member must not be sufficiently rigid to prevent local buckling

(c) elements of member should be thin to prevent local buckling

(d) elements of member need not prevent local buckling

This question was posed to me in an online quiz.

My doubt is from Behaviour of Compression Members & Types of Sections topic in division Design of Compression Members of Design of Steel Structures

Answer 1

Right option is (a) member must be sufficiently rigid to prevent general buckling

The explanation is: Member must be sufficiently rigid to prevent general buckling in any possible direction, and each element of member must be thick enough to prevent local buckling.
