乌兰察布城展馆主体形式为钢筋混凝土框架-剪力墙,内部存在空间钢桁架、双层钢网壳等多种结构类型,存在大悬挑、错层、钢与混凝土连接、钢结构异形节点等。双层球幕钢网壳作为悬挑桁架的支点,也是设计的一个亮点和难点。从结构基础选型到主体结构整体分析、从钢结构整体计算设计思路到复杂关键节点分析均进行了详细的阐述,重点利用PKPM及MIDAS两种软件对主体结构进行了多遇地震下的反应谱分析和弹性时程分析,并将结果进行比较。对双层球幕球壳结构进行分体计算,确保结构的经济及安全性。
Wulanchabu City Pavilion main form of reinforced concrete frame - shear wall, the internal existence of space steel truss, double steel mesh shell and other types of structures, there is a large cantilevered, staggered, steel and concrete connections, steel structure Alien nodes. Double spherical steel shell reticulated truss as the fulcrum, but also design a bright spot and difficulties. From the selection of the structure foundation to the overall analysis of the main structure, from the overall design and calculation of steel structure to the analysis of complex key nodes, the PKSC and MIDAS software are applied to the main structure under the earthquake spectrum Analysis and elastic time-history analysis, and compare the results. Double sphere dome shell structure calculated separately to ensure the economy and safety of the structure.
