摘　　要：为研究预制钢筋混凝土剪力墙结构抗震性能,在实验室中建成三层足尺模型,对其进行了弹性阶段拟静力试验,详细介绍了试验模型的设计与制作过程,重点介绍了模型各构件之间的连接技术,给出了试验模型在低周往复荷载作用下的滞回曲线、刚度退化曲线及各级荷载作用下刚度退化的详细数据。刚度退化分析表明,预制钢筋混凝土剪力墙结构在出现可见微裂缝之前试验模型的刚度退化很显著,说明预制构件之间的变形能力较强,势必会提高结构的整体抗震耗能能力。这一预制钢筋混凝土剪力墙结构的新特点,需要进一步的试验研究和分析,使其在抗震中发挥有利作用。In order to study the seismic behavior of precast reinforced concrete shear wall structure,a three-story full-scale model was built in laboratory for an elastic quasi-static test and an elasto-plastic pseudo-dynamic substructure test.This paper introduces the design of the experiment model and the construction process including the key connection technique.Then the quasi-static test of the full-scale model is described.This paper presents the hysteretic curves,stiffness degradation curve and the detailed data of stiffness degradation of the full-scale model under cyclic loading.The initial study on the dynamic characteristics is presented and is the basis of the following pseudo-dynamic substructure test.The stiffness degradation analysis shows that the stiffness degradation is significant before visible micro cracks are developed on the precast reinforced concrete shear wall test model.This indicates that the overall seismic energy dissipation capacity of the structure can be enhanced if the connections between precast members have adequate deformation capacities.This new feature of precast RC shear wall structure still needs further experimental and theoretical studies so that it can be applied in actual seismic design.
