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.关键词
