Abstract
This paper deals with the elastoplastic analysis and ductility evaluation of steel tubular columns subjected to cyclic loading. The basic characteristics of steel tubular columns are noted. The results of finite element analyses on cyclic elastoplastic behavior of steel tubular columns are presented. For comparison purposes, in the analysis three material models; kinematic hardening, isotropic hardening, and elastic perfectly plastic models are employed for material nonlinearity to trace the inelastic cyclic behavior of steel. A method for evaluating ductility capacity of tubular columns is presented. The application of the method is demonstrated by comparing the computed strength and ductility of some cantilever columns with the test results.
