摘　　要：叠合剪力墙的抗震性能研究可为发展节能环保型钢筋混凝土叠合结构体系提供科学依据。文章对3片预制预应力混凝土钢筋桁架叠合剪力墙和1片现浇剪力墙进行了拟静力试验,对比了试件的裂缝发展情况和破坏形态,分析了试件的承载能力、滞回曲线、骨架曲线、耗能性能、剪切变形、刚度退化等抗震指标。结果表明:预制预应力混凝土钢筋桁架叠合剪力墙与现浇剪力墙的破坏形态相近,具有良好抗震性能;预制叠合板中布置的横向预应力筋可有效延缓叠合剪力墙斜裂缝出现的时间,减少了斜裂缝的倾斜角度;两种边缘构造形式均可保证叠合剪力墙的整体性,其中现浇混凝土长度大的叠合剪力墙构件延性和剪切变形能力较优。The study of seismic behavior of superimposed shear walls is the scientific basis for the development of energy saving and environmental protection steel concrete superimposed structures.Quasi-static tests are carried out on three pieces of precast prestressed concrete steel bar truss superimposed shear walls and one piece of cast-in-place shear wall.The crack development and failure patterns between the specimens are compared.The bearing capacity,hysteresis curves,skeleton curves,energy dissipation,shear deformation and stiffness degradation of the specimens are analyzed.The test results indicate that the failure patterns of precast prestressed concrete steel bar truss superimposed shear walls are similar to that of cast-in-place shear walls which have good seismic behavior.The transverse prestressed bar in precast wall panels can effectively delay the occurrence time of inclined cracks in superimposed shear walls and reduce the inclined angle of inclined cracks.The two kinds of edge structures can ensure the integrity of the superimposed shear walls,and the ductility and shear deformation capacity of the superimposed shear walls with long cast-in-place concrete length is slightly better.
