| Summary: | Steel plate shear wall (SPSW) is a structure system which is mainly used in high-rise building to resist the lateral load either from the wind or earthquake. In this study, several models of perforated steel plate shear wall were analysed by using Abaqus software in order to study the behaviour of perforated steel plate shear wall with different aspect ratios when the location and size of the of opening are varied. The parameters concerned are ductility, energy dissipation and lateral load capacity of the perforated SPSW. 4 meter high perforated steel plate with varying width of 4 m and 6 m are bounded by vertical and horizontal boundary elements which is fixed at its base and restrained at z-direction at the top. The plate and boundary element were made from A36 steel and ASTM A992 steel respectively. Cyclic loadings were applied laterally for each SPSW model and the lateral displacements at the top of the model were recorded to plot hysteretic curve in order to obtain the ductility, energy dissipation and lateral load capacity. It has been found that the energy dissipation, ductility and lateral load capacity are affected by the different location of the perforation in the SPSW, where SPSW with perforation that is closer to the acting forces has lower energy dissipation, ductility and lateral load capacity. Maximum energy dissipation, ductility and lateral load capacity were achieved when the perforation was located at the centre of the SPSW. The increase in size of perforation of the SPSW caused the energy dissipation, ductility and lateral load capacity to decrease, while wider width of SPSW have larger values for energy dissipation, ductility and lateral load capacity. |
