云南昆明博物馆新馆基础隔震结构楼层谱分析

云南昆明博物馆新馆位于高烈度区,采用铅芯叠层橡胶隔震支座及普通叠层橡胶隔震支座组合基础隔震体系.由于结构内部附属结构物在大震甚至中小震作用下可能发生损坏,造成巨大损失,为此,采用楼层反应谱来分析附属结构物在地震作用下的反应和抗震性能.通过建立主结构分别为基础隔震与基础固定的三维有限元模型,应用基于加速度时程输入的时程分...

Floor Response Spectrum of Base-isolated Building of New House of Kunming Museum in Yunnan Province

Kunming museum new house,which is located in high seismic fortification intensity region,is base isolated with both lead rubber bearings(LRB) and rubber bearings(RB).Secondary systems in the primary structure may be damaged and suffer heavy losses under rare earthquake or even moderate and frequent earthquake.Floor response spectrum is usually used to evaluate the response and seismic performance under the seismic input.The three-dimensional finite element models of both the base-isolated and fixed-base str...
