摘要
为分析装配式型钢约束混凝土剪力墙结构体系的抗震性能,文中对1/2 缩尺单跨三层试件利用力-移混合控制方法拟静力加载试验,分析试件的骨架曲线、刚度退化曲线以及耗散性能以及延性性能.结果表明,装配式型钢约束混凝土剪力墙结构第一层、第二层以及第三层最大荷载对应的位移分别为10、25、30 mm.随着层数的增高,结构刚度不断下降,结构的能耗值以及等效阻尼比不断降低.反向加载条件下结构的承载水平有所降低,正、负向加载条件下结构的延性系数分别为4.5 和5.6,超过3 即表明结构的延展性良好,具有良好的抗震性能.
Abstract
In order to analyze the seismic performance of prefabricated steel restrained concrete shear wall structure system,the skeleton curve,stiffness degradation curve,dissipation and ductility of 1/2 scale single-span three-layer specimens were analyzed by pseudo-static loading test using the force-displacement hybrid control method.The results show that the displacement corresponding to the maximum load of the first,second and third layers of the prefabricated steel restrained concrete shear wall structure is 10,25and 30 mm,respectively.With the in-crease of the number of layers,the stiffness of the structure decreases continuously,and the energy consumption and equivalent damping ratio of the structure decrease continuously.Under reverse loading,the bearing level of the structure is somewhat reduced.Under positive and nega-tive loading,the ductility coefficients of the structure are 4.5 and 5.6 respectively,exceeding 3,which means that the structure has good duc-tility and good seismic performance.
