Today, steel braced frames are very common due to their appropriate potential in absorbing the input energy. In these frames, the gusset plates, which connect the brace to the boundary elements of the frame, play an important role in the transmission of lateral forces. The behavior of these members can be studied under tensile and compressive loads. In the present study, a comprehensive numerical three-dimensional (3D) nonlinear finite element (FE) study was done to investigate the behavior of concentrically braced steel frames under cyclic loading. Parameters including the dimensions of the gusset plate, the thickness of the gusset plate, and different types of stiffeners are considered in this study. The results revealed that the edge stiffener changes the buckling mode and increases the ductility and compressive capacity of the model. The longitudinal stiffener does not cause a noticeable change in the buckling mode of the connection but improves the compressive capacity and ductility of the connection. Edge stiffeners do not have a significant effect on the post-buckling strength of the connection but contribute to the stability of the connection in the post-buckling area, which leads to higher post-buckling strength. The effect of edge stiffeners on increasing the buckling strength seems to depend on the thickness of the gusset plate. Furthermore, the out-of-plane deformation of the gusset plate is significantly dependent on the presence of an edge stiffener, especially when compressive loading causes the connecting plate to buckle.
