Abstract
Semi-supported steel plate shear walls (SSPSWs) system has been attracted the attention of researchers' interest with maintaining positive performance and reducing defects in conventional steel plate shear walls, that including stress reduction in the main columns. In the current paper, the impact of thickness and type of infill plate materials (high-strength steel ASTM A572 with yield stress (YS) of 345 MPa, Medium-yield A36 steel with the YS of 245 MPa, Low-yield steel LPY100 with the YS of 100 MPa) on the loading capacity, energy absorption and behavior ratios (stiffness K], behavior ratio R], ductility ratio mu]) of SSPSWs are evaluated. For this purpose, 12 shear walls were modeled in the ABAQUS software. Results showed that the loading capacity and energy absorption of SSPSWs with ASTM A572 infill plate is more than other models and the ductility ratio of SSPSWs with LPY100 infill plate is higher than that of others. Therefore, for SSPSWs with infill plates type of ASTM572, A36, and LPY100 and with a thickness of 2 mm, the ductility ratios are 2.919768, 3.42301, and 5.117279, respectively.
