Practice Question: Critical Buckling Load of Steel Bar under Axial Compression Load

NCEES Civil PE Specification Analysis of Structures–Forces And Load Effects: Special Topics


Problem

Under axial compression, a rectangular steel bar measuring 1.5 inches in width, 2 inches in thickness, and 5.75 feet in length, is constrained at both ends.

Given a modulus of elasticity of \(E = 29000 \ ksi\), determine the critical buckling load.

Consider an effective length factor of \(K = 1\)
