[摘要] 沈阳市第二中学食堂扩建工程由于场地限制，且房屋高度及室内净高有严格要求，因此选用了钢筋混凝土筒、刚接钢桁架大跨度连体结构，跨度为55. 8m，各层均为无柱空间。采用MIDAS/Gen软件进行了抗风、抗震、温度应力及关键构件失效分析，并与SATWE计算结果进行了比较，据此进行结构设计。整体结构简洁美观，满足了场地及建筑功能要求。

Abstract: According to limits of ground and the building height and clear height, the extending project of refectory in Shenyang NO.2 High School adopted the large-span siamese structure. The structure is combined of concrete tube and rigid truss. Analyses of wind and seismic load,temperature stress and invalidation of key structural components have been proceeded by MIDAS/CEN commercial software. Compared with the results by SATWE,the structure design was produced. The completed building satisfies both design standards and appearance demands.
Keywords: MIDAS/Gen; truss, connected structure
