N2 - Concentrically braced frames (CBFs) are increasingly used in the construction of steel buildings located in moderate and high seismic regions. Wide flange (WF) sections represent a possible alternative to hollow structural steel sections as bracing members. The effects of plate thickness (tab or stiffener or gusset) and the number of bolts on the hysteresis response and fracture a single-bay WF steel braced frame subjected to reverse axial displacements has been assessed through a parametric study using finite element modelling. It is found that reducing the number of bolts while increasing their diameter and the thickness of tab-plates to satisfy the AISC standards for tab-plate connection design had negligible effect on the hysteresis response of the single-bay braced frame.
