摘要:
形状不规则建筑物在地震作用下极易发生扭转效应的破坏,而减小不规则结构的扭转效应是保证其抗震性能的重要途径。研究结构扭转效应的控制方法,可以为不规则结构抗震性能的保障提供依据。文章以平面形状不规则的框架结构为例,采用数值分析方法,对设置不同隔震层的结构进行了模态分析和地震反应计算,通过比较不同隔震方案的结构层间扭转角研究了结构扭转效应的控制效果。结果表明:基础隔震建筑上部结构的地震反应比非隔震建筑地震反应明显降低,扭转效应也显著减小;采用橡胶支座加滑板支座的组合隔震体系比全部采用橡胶支座的减震效果更优;通过调整支座布置方式,可以使不规则结构的扭转效应得到有效控制。
Abstract:
Under the action of earthquake, the irregularly shaped structure would be destroyed due to obvious torsion effect. Reducing the torsion effect is an important approach to ensure the seismic performance of irregular structure. The research on the torsion effect control could provide evidence to ensure the seismic performance of irregular structure. With numerical analysis method, the seismic responses of an irregularly shaped frame structure with different isolation layers were calculated in this paper through comparing relative torsion angle of structures with different isolation layer. The results show that the seismic responses of baseisolated buildings are significantly lower than those of nonisolated building, as well as the torsional responses. The combined system is more effective in seismic isolation than the rubber bearings alone. Torsional responses of irregularly structure are effectively controlled by adjusting the bearing arrangement.
