Abstract
Corrugated steel plate shear wall (CSPSW) is one of the lateral resistance systems which consists mainly of steel frame (beam and column) with vertical or horizontal corrugated steel plate connected to the frame by weld, bolts or both. This type of steel shear wall characterized by low cost and short construction time with high strength, ductility, initial stiffness and excellent ability to dissipate energy. The aim of this paper is to evaluate the effect of corrugation angle and its direction on the performance of CSPSW under cyclic loading. The Finite element analysis was employed to achieve the research aim. The FE models were validated with experimental data available in the literature. Results reveal that the corrugation angle has a clear influence on initial stiffness, strength, ductility, and energy dissipation of CSPSW. The optimum performance of CSPSW can be obtained with angles of 30o for CSPSW with vertical corrugation and 20o for CSPSW with horizontal corrugation. The use of CSPSW with vertical corrugation provides higher strength, stiffness, and ductility compared to CSPSW with horizontal corrugation. Therefore, it is recommended to use CSPSW with vertical corrugation.
Highlights
Steel plate shear walls (SPSWs) are lateral force resisting system
Corrugated Steel Plate Shear Wall (CSPSW) is a new type of lateral load resisting system within the family of steel plate shear walls, which consists of a steel boundary frame and a corrugated steel plate wall panel
The ribs are one of the advantages of the geometric shape of the corrugated plate. They act as stiffeners to the plate and they proved to improve ductility, initial stiffness, energy dissipation, and the ability to oppose the gravity loads compared with SPSW
Summary
Steel plate shear walls (SPSWs) are lateral force resisting system. They have seen increased in usage over the last thirty years. The study showed that the strength in corrugated steel plate was reduced by 17% and the ductility ratio, the energy dissipation, and the stiffness was increased by 40, 52 and 20 % respectively compared with the simple plate. Hosseinzadeh et al [11] studied the linear buckling analysis of flat and corrugated steel shear wall using finite element They confirmed that reducing the width of the horizontal side of the trapezoidal corrugated panels can only change the buckling type from local to global without any increase in buckling strength. Guo, and Zuo [13] studied the elastic buckling and load-resistant of double corrugated steel plate shear walls using finite element and compared the results with the theoretical formulas of the rigidity constants. The influence of each parameter was evaluated through the initial stiffness, ductility, strength, and the dissipated energy
