چکیده مقاله:

Special Concentrically Braced Frame (SCBF) is increasingly utilized as a Seismic Force Resisting System in steel structures. SCBF systems are expected to undergo a significant amount of inelastic deformation during a severe earthquake. The strength of brace connections are thought as one of the most effective parameters on the inelastic behavior of these systems. In this paper, the effect of the slenderness ratio of the compressive area of Gusset Plates on the ductility and energy dissipation of the SCBF systems is studied. Several concentrically braced frames with different amounts of slenderness ratios were analyzed by nonlinear finite element method. The models were subjected to cyclic loads, and seismic characteristics of the braced systems were compared.
