［摘要］云南省博物馆新馆采用型钢混凝土（SRC）框架-钢支撑结构，在主体结构底部与地下室顶板之间设置隔震层，有效解决了设防烈度高、结构复杂的技术问题。对结构采用时程分析法进行了计算，并经模拟地震振动台试验验证，隔震效果良好；采用带刚性水平支撑的大跨钢桁架、设置水平限位杆和采用柔性连接等措施解决中庭金玉满堂悬吊结构设计的问题，并采用竖向密肋板解决建筑折板外墙的问题。

Abstract:SRC frame-steel brace structural system is adopted   and isolation layer is  set between main structure bottom and basement roof  in the structural design of New  Yunnan Provincial Museum，which verified good effect to solve the problems of high seismic precautionary intensity and complicated structure. The result of structural calculation with time-history analysis method verified by scaled model simulation with shaking table tests shows good isolation effect of the structure. The suspension structure in the atrium was designed according to the measures by setting large-span steel truss with rigid horizontal support, horizontal spacing rod and flexible connection. The vertical ribbed slab was adopted to solve the problem of folding exterior wall of the building.

Keywords:New  Yunnan Provincial Museum; SRC frame; steel brace; isolated structure; suspension structure
