［提要］广东省博物馆新馆采用新颖的大跨度悬挂结构体系，结合该结构的特殊性，采用国内外几个大型的有限元程序MIDAS/GEN,ETABS,PMSAP等进行整体计算，各项计算参数以及计算模式都进行了仔细分析后再行选用。除普通的计算模式外，还对施工加载、温度效应、预应力、阻尼器等作用进行了分析，另外还针对施工过程进行了详细的计算分析。弹塑性分析方面采用ABAQUS进行计算，对上部的空间钢桁架及其节点进行了ANSYS分析。从计算结果来看，结构抗震性能良好，主要控制指标均满足规范要求，具有足够的安全性。多个分析方法的结合，确保工程做到“安全、经济、合理”。

Abstract: The novel long span suspension structure system is adopted in Guangdong Province Museum. Considering the particularity in structure, the integral analysis is performed with several large-scale FEM software from home and aboard, e.g. MIDAS/GEN, ETABS, PMSAP etc. Each computation parameter and pattern is carefully analyzed before selection. Besides ordinary computation pattern, construction loading, temperature effect, pre-stressed, dampers are all involved, moreover construction stage loading simulation is carried. The elasto-plastic analysis is finished with ABAQUS, the upside spatial steel truss and the node analysis is computed with ANSYS. Seeing from the calculation result, aseismic performance of is well, and  the primary control target satisfies the standard request. The structure has enough safety. Integral computation methods guarantee the solution to be safe, economical and reasonable.
