Question

The buckling coefficient for thin flat plate free along one longitudinal edge is given by

(a) k = 0.425 + (b/a)

(b) k = 0.425 + (b/a)^2

(c) k = 0.425 + (a/b)^2

(d) k = 0.425 – (b/a)^2

This question was addressed to me in a job interview.

The above asked question is from Local Buckling of Plates in division Plastic and Local Buckling Behaviour of Steel of Design of Steel Structures

Answer 1

Right option is (b) k = 0.425 + (b/a)^2

The best explanation: For a thin plate simply supported along both transverse edged and one longitudinal edge and free along the other longitudinal edge, the buckling coefficient can be approximated by k = 0.425 + (b/a)^2.
