The effect of edge stiffener on compressive behavior of Gusset plate

The Gusset plates are sheets that were utilizing for connection and transportation of force between brace and beam or column in frame. These plates have complex behavior subjected to compressive force because different failure modes. The edge buckling is one of the common failure modes in large dimension Gusset plates. The edge stiffeners have been recommended for against of edge buckling and increasing the ultimate bearing capacity and ductility of Gusset plate. In this paper, the model of Gusset plate has been simulated with considering of boundary members stiffness, nonlinear behavior of material and initially imperfection by ANSYS finite element software. These models have been verified to experimental activities of Yam and Cheng (1993). The effect of edge stiffeners on compressive behavior of Gusset plate and the thickness of Gusset plate effect on edge stiffener are studied. The result demonstrated that the edge stiffeners improve the behavior of Gusset plate and with increasing the Gusset plate thickness increased the effect of edge stiffener in total compressive behavior of steel Gusset plate
