Question

Effective length of compression member is ________

(a) distance between ends of members

(b) distance between end point and midpoint of member

(c) distance between points of contraflexure

(d) distance between end point and centroid of member

The question was asked by my college professor while I was bunking the class.

My doubt is from Effective Length and Slenderness Ratio of Compression Members in division Design of Compression Members of Design of Steel Structures

Answer 1

The correct answer is (c) distance between points of contraflexure

To explain: Effective length of compression member is distance between points of contraflexure. It should be derived from actual length and end conditions.
