Abstract
Wide flange (WF) section members represent an attractive alternative to tubular braces to resist seismic excitations in braced frames. In the current study, an average true stress-true strain curve is proposed and used to model six large-scale WF brace members in combination with a refined fracture model. The effects of various material and geometric parameters are investigated. Increasing or reducing either or both the strength and the thickness of gusset plates by 10% or 20% has negligible effect on the hysteresis behaviour under reverse cyclic loading and the fracture of the large-scale WF brace members analysed.
