摘要：对3个普通配筋高性能混凝土剪力墙(HPCW)试件和3个配制型钢高性能混凝土剪力墙(SHPCW)试件进行拟静力试验基础上,分别对其破坏形态、承载能力、变形能力、耗能能力等进行了对比研究分析。研究结果表明:配制型钢高性能混凝土剪力墙和普通配筋高性能混凝土剪力墙相比,前者的开裂荷载、屈服荷载和峰值荷载分别是后者的1.12~1.57、1.15~1.50、1.13~1.59倍,配制型钢高性能混凝土剪力墙具有较高的承载能力;配制型钢高性能混凝土剪力墙位移延性系数是相同剪跨比的普通配筋高性能混凝土剪力墙的1.05~1.30倍,总耗能值前者是后者的1.3~1.7倍,配制型钢高性能混凝土剪力墙具有较好的耗能能力。设置型钢的暗柱作为约束边缘构件可以对剪力墙提供有效约束,较显著地增加了剪力墙的变形能力和耗能能力。
Based on the quasi-static tests of three high-performance concrete shear walls with profiled steel and three high-performance concrete shear walls with common reinforcement,the failure modes,bearing capacity,deformation capacity and energy dissipation capacity are analyzed and compared.The results show that the cracking load,yield load and peak load of the former are 1.12~1.57 times,1.15~1.50 times and 1.13~1.59 times of the latter,respectively.The shear wall with steel reinforced high-performance concrete has higher bearing capacity.The displacement ductility coefficient of steel reinforced high-performance concrete shear wall is 1.05~1.30 times of the latter.The total energy consumption of the former is 1.3~1.7 times of that of the latter.The shear wall with steel reinforced high-performance concrete has better energy dissipation capacity.As a restrained edge member,the concealed column with profiled steel can effectively restrain the shear wall,and significantly increase the deformation capacity and energy dissipation capacity of the shear wall.
