Analytical study on gusset plate behavior of braced frames through finite element method

Nowadays, it’s common place to use concentrically braced frames (CBFs) for lateral-load resisting systems in steel structures sporadically. Gusset plate connections play an outstanding role to connect the beams and columns in CBFs systems, so need to be taken into center of attention in designing of CBFs. This analytical study has illustrated that buckling capacity of CBFs under a monotonic loading can be improved by considering the behavior of gusset plate connection through designing its thickness and size. In this paper, experiment results and finite element model have been verified, in addition, it indicates that CBFs performance depend upon gusset plate connections, consequently.
