双向斜置波纹钢板剪力墙抗震性能试验研究
Experimental study on the seismic behavior of cross-slanted corrugated steel plate shear walls
摘要
Abstract
To address the issue of out-of-plane buckling in flat steel plate shear walls,this paper proposes a new type of cross-slanted corrugated steel plate shear wall(CCSPW)with enhanced out-of-plane buckling-restrained performance.The study aims to investigate the influence of the corrugation angle on its seismic performance.To this end,three 1/3-scaled CCSPW specimens were designed and manufactured.The experimental study was conducted using the MTS loading system,focusing on various seismic performance indicators,such as initial stiffness,bearing ca-pacity,failure process and form,energy consumption capacity,and ductility under low cyclic loading.The results show that CCSPWs can effectively prevent out-of-plane bulging under low cyclic loading,showcasing excellent lateral bearing capacity.The cross-slanted corrugated steel plates,subject to a joint force of tension and pressure,effectively improve the initial stiffness of specimens.Notably,the CCSPW specimen with an oblique angle of 60° exhibits the greatest ini-tial stiffness.The specimen with an oblique angle of 45° shows a bearing capacity that is 5.5％and 10％higher than those of the other two specimens,along with the highest ductility coefficient and superior ductility.Additionally,the specimen with an oblique angle of 60° displays the largest equivalent viscous damping coefficient,ranging from 2％to 5％higher than those of the other two specimens,indicating excellent energy dissipation capacity.关键词
