【摘要】 通过对大型火电厂主厂房纵向框—剪体系进行拟动力试验 ,研究了此类结构的受力特点、破坏过程、滞回特性、延性、位移反应及耗能能力 ,并提出了改进结构抗震耗能的建议 ;分析了结构构件合理的屈服顺序 ,通过对试验的骨架曲线进行回归分析 ,得出了结构刚度退化规律 .更多还原

【Abstract】 According to the model pseudo dynamic test of the longitudinal frame shear wall structure of main factory building in a large thermal power plant,the paper investigates the loading behavior,faiure proceeding ,ductility,energy consumption capacity,and the displacement behavior,and puts forward suggestions for improving the structural asseismic behavior. A rational yielding sequence of structural members are analyzed. Finally,the loss law of structural rigidity based on the regression to load displacement skeleton points of the test is obtained.更多还原
