Abstract

ECCENTRIC BRACED FRAMES (EBF) are widely used in steel structures in which the beam-column connections usually have a nonlinear semi-rigid behavior.This behavior greatly influences that of the Eccentric Braced Frame. In this research, all parts of the steel frames including beam-column connections were modeled three-dimensionally using shell elements. The nonlinear static push over analysis was used for these frames in ANSYS. In the first stage, the effects of the connections on lateral ultimate strength, capacity of energy dissipation, elastic stiffness, and EBF ductility factor were investigated. The results showed that the seismic behavior of the semi-rigid EBF was better than both the simple and the rigid EBFs. In the second stage, the effect of the LINK BEAM length was studied and the nonlinear and seismic behaviors of EBF were compared for a variety of situations. Finally, the best length of the LINK BEAM in the semi-rigid EBF was determined.
