英文摘要	The FEM simulation analysis method is studied in the paper for estimating ultimate bearing capacity of cold-formed steel portal frame, in which beam-spring system is used to simulate performance of joints and initial imperfect of frame components is considered, and the deformation performance and failure features of portal frame structure under vertical loads are also studied. The analytic results of the FEM simulation analysis method are close to the values of experiment. The ultimate bearing capacity of portal frame were computed by means of changing the following parameters, which include the web plate thickness, the flange width, the plate thickness of brackets, the portal frame roof incline, and the column footing stiffness. The analytic results indicate that the ultimate bearing capacity can be improved when the parameters mentioned above are increasing.
