摘　　要：目的为新型叠合板式混凝土剪力墙结构体系在国内的推广、工程设计方法、施工工艺和降低施工成本等提供可靠的理论科学依据.方法采用试验研究和理论分析相结合的方法,对三片剪力墙试件的抗震性能进行了验证性低周反复加载试验研究,再从理论角度对其在水平单调荷载作用下性能进行非线性有限元分析,进一步了解该种新型结构在水平荷载作用下的反应.结果叠合板式混凝土剪力墙结构在竖向拼缝处有可靠构造措施连接情况下,通过后浇混凝土形成整体结构后,其破坏形态、整体性、承载力、延性及耗能等抗震性能可认为与现浇钢筋混凝土剪力墙结构无异.结论有限元计算结果与试验结果较为吻合.In order to provide a reliable theoretical scientific basis for the wide use,engineering design method,construction technology and cost reduction of the structural system of the new superimposed slab concrete shear wall,the paper combines the experimental study with theoretical analysis.The verifying experiment on seismic performance of 3 shear wall samples under the low-cycle repeated load is carried out.The non-linear finite element analysis on the performance of the samples under horizontal unidirectional load is carried out in order to provide further understanding about the response of the new structure under the horizontal load.The results show that after pouring concrete to form overall structure with reliable structural measures at the vertical joint seam,the seismic performance such as failure modes,integrity,bearing capacity,ductility,and energy dissipation of superimposed concrete wall panels＇ structure is the same as that of the general full-spot-pouring shear wall structure.The finite element results are compared with the experiment ones,and they agree well with each other.
