【摘要】 装配式建筑快速发展背景下，针对剪力墙连接可靠性对结构性能的影响，提出由两片“L”型预制墙板中间现浇混凝土构成的新型模块化集成建筑剪力墙。通过低周反复加载试验对比两片夹心剪力墙与现浇剪力墙的抗震性能。结果表明：试件均呈现弯剪破坏特征，夹心剪力墙沿接缝处产生裂缝，最后被分割成几部分；夹心剪力墙极限承载力（平均值1968.41 kN）较现浇剪力墙（2130.95 kN）低7.62%，延性系数（2.18）较现浇剪力墙（2.24）低2.75%。夹心剪力墙相较于现浇剪力墙展现出更好的耗能能力。更多还原

【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.更多还原
