【摘要】 利用子结构试验技术,对三层底部框支配筋砌块短肢砌体剪力墙足尺模型进行拟动力子结构试验,模拟底部一层框架上部五层配筋砌块短肢剪力墙结构在地震作用下的反应。研究该结构在地震作用下的破坏过程、破坏形态和变形能力,给出结构各层的位移时程曲线、层间滞回曲线。试验结果表明,该结构具有较好的整体抗震性能,可满足我国规范7度设防区多道抗震设防的设计要求。更多还原

【Abstract】 In order to study the seismic behavior of a five-story frame-supported reinforced concrete short-limb masonry shear wall structure,a pseudo-dynamic substructure test for a full-scale three-story frame-supported reinforced concrete short-limb masonry shear wall was carried out.The failure process,deformation capacity,dynamic response time-history and hysteresis characteristics of the structure under seismic action were determined.The test results indicate that the structure has good global seismic performance and can satisfy the design requirements for multi-story seismic resistant structures against earthquakes of degree 7 defined in China’s code.更多还原
