不规则结构的扭转效应控制研究
Research on the torsion damages control of irregular structure
摘要
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 nonisolated 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.关键词
