The Influence of Low Yield Point Steel (LYP) and Plate Thicknesses in Post-buckling Behavior and Ultimate Strength of Semi-Rigid Steel Plate Shear Walls

In semi rigid shear walls, the shear wall won’t be connected to the main columns of the structure frame. Instead, it will be connected to the secondary columns which are used for tension field in plate. In this paper, post buckling behavior and ultimate strength of semi rigid steel shear walls with different thicknesses and different yield stresses have been compared according to different analyzing methods, such as plate-frame interaction model (PFI), strip model and finite element method. The results show a good compatibility between these methods. Results show that using low yield point steel (LYP) in semi rigid shear walls is appropriate. The influence of plate thickness increasement on initial stiffness and ultimate strength is more than the yield stress increasement effect
