[摘要] 沈陽市第二中學(xué)食堂擴(kuò)建工程由于場(chǎng)地限制，且房屋高度及室內(nèi)凈高有嚴(yán)格要求，因此選用了鋼筋混凝土筒、剛接鋼桁架大跨度連體結(jié)構(gòu)，跨度為55. 8m，各層均為無柱空間。采用MIDAS/Gen軟件進(jìn)行了抗風(fēng)、抗震、溫度應(yīng)力及關(guān)鍵構(gòu)件失效分析，并與SATWE計(jì)算結(jié)果進(jìn)行了比較，據(jù)此進(jìn)行結(jié)構(gòu)設(shè)計(jì)。整體結(jié)構(gòu)簡潔美觀，滿足了場(chǎng)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
