| Abstract: | In this paper, the elastoplastic columns are discussed whieh stress-strain relationship is expressed by a power scries, non-linear differential equations for post-buckling of spring-hinged cantilever columns are established. The general solutions of the equations are given and some numerical results of columns with variable and constant cross sections are obtained by using perturbation method. |
