【摘要】 将摩擦滑移隔震支座作为滑动装置进行建筑整体平移,结构就位后再连接橡胶隔震支座组成并联复合隔震结构体系。这种施工方法平移启动力较小,启动时对结构产生的振动小,提高了平移施工速度,降低了施工难度并通过改变结构的动力特性改善了建筑的抗震性能。通过某文物建筑平移实例研究这种方法的施工工艺,为工程应用提供依据。通过对就位连接后的建筑进行有限元分析,分析结果表明:复合隔震技术对降低结构地震反应有显著作用。更多还原

【Abstract】 As the slipping device in integral migration of a building,the friction-sliding isolation bearings together with the rubber isolation bearings which is used after the structure taking its place compose the parallel composite isolation system.By applying this method,it will save effort,have a lower vibration to the structure,increase the working efficiency,reduce the construction difficulty,and improve the seismic capacity by changing dynamic characteristics.In this paper,the construction technology of the method was researched in a integral migration project of cultural relics,which provided a reference for project design and application.It was proved that the technique of parallel composite isolation analysed by the general finite element software could reduce structural seismic response significantly.更多还原
