Abstract

Steel plate shear wall (SPSW) is known as an effective structural system in high rise building that provides lateral resistance against wind or earthquake. SPSW sometimes, needs to be perforated to provide access for human which may reduce the capability of SPSW in resisting the lateral load. This study investigated the effect of size and location of perforation to the lateral resistance of SPSW. This study was done numerically by varying the sizes and locations of perforation in the SPSW, while monitoring the horizontal displacement of the top side of SPSW. The first set of models had perforation of 1.2 m wide and 2 m high being placed at different location in the SPSW models, while the second set of models had varying sizes of perforation at the centre of the SPSWs. Both sets of the SPSWs were 4 m high with two different widths, which were 4 m and 6 m. Cyclic loadings were applied laterally for each SPSW model as according to ATC24 and the displacements at the top side of the SPSW model was obtained from the analysis. Hysteretic curves of all models were plotted to obtain the energy dissipation, lateral load capacity and ductility. It is found that perforation that is located nearest to the edge of the SPSW lowers the energy dissipation, ductility and lateral load capacity the most. Larger size of perforation of the SPSW caused larger reduction of the energy dissipation, ductility and lateral load capacity, while wider SPSW have larger values of energy dissipation, ductility and lateral load capacity.
