Analytical study on the effects of orientation and thickness of FRP in the semi-supported steel shear walls reinforced by FRP

Semi-supported steel shear walls (SSSW) are lateral load resisting systems. In this new type of steel shear walls, the shear wall was not connected directly to the main columns; instead it was connected to the secondary columns that is not under gravity loads and which are used for tension field in plate. For reinforcement and improvement of behavior of semi-supported steel shear wall, fiber reinforced polymers (FRP) can be used. In this research, nonlinear behavior of composite semi supported steel shear walls (CSSSW) were resisted by the fiber reinforced polymers (FRP) were studied. The seismic performance factors in the proposed system, were evaluated the effects of FRP's orientation and FRP's thickness. The results showed that, installation of FRP increase energy dissipation capacity and ultimate strength. In addition, thicken FRP layers up to optimal amount improved composite semi supported steel shear walls (CSSSW) behavior
