In this paper, the finite element simulation software ABAQUS was used to study the hysteretic performance of Q690 high-strength steel (HSS) and high-web box-section steel columns. The finite element model was established by solid elements, and the influence of the initial defects of materials on the specimen was considered. The hyteretic performance of the specimen was conducted by analyzing and comparing the width-thickness ration of the flanges and the width-thickness ration of the webs. The results show that the increase of width-thickness ratios of the webs and flanges will reduce the hysteresis performance, the energy dissipation capacity and the ultimate horizontal bearing capacity of the specimen.
