Abstract

In this paper, the behavior of gusset plates in concentric braced steel frames under cyclic loading has been studied. The behavior is studied by comparing dissipated energy, plastic strains of welds between the gusset plate and beam, column and bracing, plastic strains at the midspan of the bracing, and Von Mises stresses and plastic strains of the gusset plates. Studied parameters are the thickness and shape of the gusset plate, use of linear and elliptical clearance, non-existence of clearance, edge, longitudinal and internal stiffeners, and use of a single- or double-profile bracing. Non-linear analysis has been performed by the finite element ABAQUS code. Obtained results showed that by eliminating the clearance, the plastic strains in weld between the gusset plate and bracing and plastic strains in the gusset plate are increased considerably. The maximum value of energy dissipation has belonged to edge stiffeners with an increase of 15.4% compared to the unstiffened gusset plate.
