Abstract :
Based on stability theory and nonlinear finite element (FE) method, ANSYS finite element models (FEM) are presented, which introduce shell181 and take geometric and material nonlinear into account. The seismic behavior of rectangular section steel members under the axial compression and the bending load is investigated. The effect of length-slender ratio, width-thickness ratio of flange and web, axial-compression ratio is demonstrated, according to the enormous calculation of various parameters. The results show that the width-thickness ratio and axial-compression ratio have generous impact on component hysteretic performance. The length-slender ratio takes a great influence on the strength degradation and plastic deformation.
