Question

What is slenderness ratio of compression member?

(a) ratio of effective length to radius of gyration

(b) ratio of radius of gyration to effective length

(c) difference of radius of gyration and effective length

(d) product of radius of gyration and effective length

This question was posed to me during an interview.

Query is from Effective Length and Slenderness Ratio of Compression Members in portion Design of Compression Members of Design of Steel Structures

Answer 1

The correct option is (a) ratio of effective length to radius of gyration

For explanation: The tendency of member to buckle is usually measured by its slenderness ratio. Slenderness ratio of member is ratio of effective length to appropriate radius of gyration (λ = kL/r). This is valid only when column has equal unbraced heights for both axes and end condition is same for particular section.
