Elasto-Plastic Mechanical Behavior of Steel Box Stub Column under Cyclic Uniaxial Tensile and Compressive Load

Abstract

In this paper, to study mechanical behavior of steel box stub column under cyclic uniaxial tensile and compressive load, elasto-plastic analysis of the segment is carried out by using ABAQUS package. In this study, with changing parameters (such as length-width ratio L/B, width-thickness ratio RR) of the box stub column, the hysteresis curves, skeleton curves, stress distribution and deformation of the ultimate state for the steel box stub-column are investigated. These results show the L/B and RR have little impact on the ultimate strength and ductility of stub-columns during the tensile stage. However, RR has obvious impact on the elasto-plastic mechanical behavior and local deformation under compressive load.
