异形柱框架-抗震墙结构振动台试验与理论分析

Shaking table test and oretical analysis on RC frame-shear wall structures with special-shaped columns

通过12层钢筋混凝土异形柱框架-抗震墙结构模型的模拟地震振动台试验及弹塑性理论分析,研究了该结构体系的动力特性、不同烈度地震作用下的反应及破坏形式.结果表明该结构体系拥有优越的建筑功能,在地震作用下呈弯剪型变形特征,传力明确,受力合理,具有良好的抗震性能和较强的抵御罕遇地震的能力,满足了小震不坏、中震可修、大震不倒的抗震设防要求,适于在中高层住宅中应用.

Theoretical analysis and experimental test on the seismic performance were conducted. The dynamic characteristics, response and destroyed form in different intensity of reinforcement concrete frame-shear wall structure with special-shaped columns were studied by ways of shaking table test and elastic-plastic analysis for a 12-story structure. The results showed that this structure system has good seismic behavior and strong capacity for resisting rare earthquake. It could meet the requirements of seismic fortification criterion and be applied to mid-highrise residentical buildings.
