What is the value of imperfection factor for buckling class a?(a) 0.34(b) 0.75(c) 0.21(d) 0.5The question was asked by my college professor while I was bunking the class.My question is based upon Design of Compression Members in chapter Design of Compression Members of Design of Steel Structures

Answer»

Right option is (c) 0.21

To EXPLAIN: The value of imperfection factor, α for BUCKLING class a is 0.21. The imperfection factor CONSIDERS all the relevant defects in real structure when considering buckling, geometric IMPERFECTIONS, eccentricity of applied loads and RESIDUAL stresses.
