在预制钢筋混凝土剪力墙结构拟静力试验研究的基础上,采用等效力控制方法对足尺试验模型进行了拟动力子结构试验,研究该结构在地震作用下的破坏过程和变形能力,获得了模型下降段试验数据,给出了结构各层的位移时程曲线、层间滞回曲线、骨架曲线、刚度退化曲线以及延性等,为该类结构在地震作用下的弹塑性分析提供了试验数据。试验结果表明:采用的水平连接技术是可靠的,能够很好地保证其在地震作用下连接性能;该结构模型属于延性结构,可以满足我国现行抗震设计规范7度设防区多道抗震设防的要求,符合“三水准”抗震设防目标,具有较好的整体抗震性能,经过合理设计可以在地震设防区使用。
Based on the quasi-static test of precast reinforced concrete shear wall structure, the equivalent force control method was used to test the pseudo-dynamic substructure of the full-scale test model, and the failure process and deformation capacity of the structure under earthquake were studied. The experimental data of the descending section of the model are given and the displacement time history, the hysteresis loop, the skeleton curve, the stiffness degradation curve and the ductility of each layer of the structure are given, which provides a test for the elasto-plastic analysis of the structure under earthquake action data. The test results show that the horizontal connection technology is reliable and can well guarantee the connection performance under earthquake. The structural model belongs to ductile structure, which can meet the requirements of multi-seismic fortification in the existing 7-degree fortified area of China’s current seismic design code , In line with the “three standards ” seismic fortification goals, with good overall seismic performance, after a reasonable design can be used in the earthquake zone.
