This study evaluated the seismic performance of precast lightweight aggregate concrete special shear walls (PLCSWs) based on the equivalency concept specified in ACI ITG-5.1. The investigation considered variations in transverse reinforcement, supplementary ties in boundary elements, and wall-to-base connection techniques. All specimens were subjected to cyclic lateral loading and constant axial loads. The results indicated that using V-ties as supplementary ties, applying the steel plate bolting technique for wall-to-base connections, and reinforcement ratio of 1.0? ??????? increased the displacement ductility ratio and cumulative work index of PLCSWs by 1.21 and 1.15 times, respectively, compared to specimens using inner crossties, spliced sleeve connection and reinforcement ratio of 2.0? ???????. For equivalent structural performance as outlined in ACI ITG-5.1, a reinforcement ratio of 2.0? ??????? and the steel plate bolting technique are essential for PLCSWs. |
