Through comparative study of different structural schemes, six reinforced concrete of oblique belly truss are used in this project based on the characteristic of architectural features, to realize the unification of structural performance and architectural configuration. Analysis and check are presented by comparing two different finite element models of SATWE and MIDAS/GEN, to ensure the security of the main structure. The roof span of auditorium is 25.2m and the steel-concrete composite structure is used. Using the setting of after pouring belt on concrete floor at the bearing, the moment at the end is released and the cracks at the bearing are avoided.Keywords: reinforced concrete; large span truss; composite floor; bearing crack作者簡介：劉若斐，碩士，一級注冊結(jié)構(gòu)工程師，Email：purplelrff@yeah.net。參考文獻(xiàn)［1］GB 50011—2010建筑抗震設(shè)計規(guī)范［S］.北京： 中國建筑工業(yè)出版社，2010.［2］GB 50010—2010混凝土結(jié)構(gòu)設(shè)計規(guī)范［S］.北京： 中國建筑工業(yè)出版社，2011.［3］北京邁達(dá)斯技術(shù)有限公司.MIDAS/GEN分析與設(shè)計原理［M］.2010.［4］李永強，劉亞坤，鄢鄰川.鋼筋混凝土桁架在大跨度工程中的應(yīng)用實踐［J］.平頂山工學(xué)院學(xué)報,2006,15(5):58-61.［5］張明. 現(xiàn)澆混凝土懸挑桁架在舞臺項目中的應(yīng)用［J］. 山西建筑,2011,37(14):29-30.
