摘　　要：叠合板式混凝土剪力墙结构由叠合墙板和其他预制混凝土构件通过可靠方式进行连接,与现场后浇混凝土形成装配整体式混凝土剪力墙结构。利用有限元软件ABAQUS对带拼缝的单面叠合板式剪力墙进行内叶板与后浇混凝土强度等级差异条件下抗震性能研究。结果表明:内叶板和后浇混凝土强度差异对墙体抗震性能影响较小。当混凝土强度等级值和考虑厚度加权混凝土强度等级值相同时,两者墙体抗震性能基本相同,与现浇剪力墙相比差别不大。分析结果可为单面叠合板式剪力墙的进一步试验研究以及工程应用提供科学依据。The composite slab concrete shear wall structure combines composite wall panels and other precast concrete components with post-cast concrete in situ to form an assembled monolithic concrete shear wall structure.Using the finite element software ABAQUS,the seismic performance of single-sided composite slab shear walls with joints was studied under different inner plates and post-cast concrete.The results show that different strengths of inner plates and post-cast concrete have little effects on the seismic performance of the wall.When the concrete strength grade and the thickness-weighted concrete strength grade are the same,the seismic performance of both walls is basically the same,and the difference is not significant compared with that of cast-in-situ shear wall.The results provide scientific basis for further experimental research and engineering application of single-sided composite slab shear walls.
