Hülya SARIKAVAK 21.12.2009 Anıl Sami ÖNEN When compressive loads are applied to short thick members, failure occurs by compressive yielding or fracture. When compressive loads are applied to long thin (slender) members, they sometimes induce sudden major changes in geometry such as bowing, wrinkling, bending or buckling. Large deflections occur that destroy the equilibirium of the structure & produce unstable configuration that leads to collapse.

BC’s at x=0 y(0)=0 B=0 at x=L y(L)=0 A=0(trivial solution) or (n=1,2,3,. ..... ) Critical load is for n=1. (euler buckling load) Define: K: radius of gyration
