Abstract：In order to study the mechanical performance of the joint with widened beam flange and perform the contrastive analysis in the difference of mechanical performance among the joint with widened beam flange, the welded joint with plug plate and the traditional steel beam-column connection joint, a connection joint with widened beam flange was designed. The mechanical properties of three types of joints under the monotonic load were analyzed with the analysis software ABAQUAS, and the application feasibility of joint with widened beam flange in the actual structure was researched. In addition, the performance difference among three types of joints were contrasted and analyzed. The results show that the joint with widened beam flange can effectively improve the stress state of the joint and the stress distribution problem in the panel zone, and make the region at the beam end where the plastic hinge appears move to the midspan of beam. Compared with the welded joint with plug plate and the traditional joint, the joint with widened beam flange has higher bearing capacity, and the stress distribution at the beam end and the column in the panel zone is more homogeneous.
