Abstract：Under the background of rapid development of assembled buildings,a new modular integrated construction sandwich shear wall was composed of two"L"prefabricated wall panels with cast-in-place concrete in the middle is proposed to address the impact of shear wall connection reliability on structural performance.Comparison of the seismic performance of the two sandwich shear walls and cast-in-place shear wall through low cycle repeated load test showed that the specimens showed bending and shear damage characteristics,and the sandwich shear wall produces cracks along the joints,which are finally divided into several parts.The ultimate bearing capacity of the sandwich shear wall(average value of 1,968.41 kN)is lower than that of the cast-in-place shear wall(2,130.95 kN)by 7.62%,and the ductility coefficient of the sandwich shear wall(2.18)is lower than that of the cast-in-place shear wall(2.18)by 2.75%.The sandwich shear wall shows better energy dissipation capacity as compared to cast-in-place shear wall.
