What is the value of non dimensional slenderness ratio λ in the equation of design compressive strength?(a) (fy /fcc)(b) √(fy fcc)(c) √(fy /fcc)(d) (fy fcc)I had been asked this question during an internship interview.This key question is from Design of Compression Members topic in division Design of Compression Members of Design of Steel Structures

Answer»

The correct option is (c) √(fy /fcc)

The best I can EXPLAIN: The value of non dimensional SLENDERNESS ratio λ in the equation of design COMPRESSIVE strength is given by λ = √(fy /fcc) , where fy is YIELD stress of material and fcc = (π^2E)/(KL/r)^2, where E is modulus of elasticity of material and KL/r is effective slenderness ratio i.e. ratio of effective LENGTH.
