(同濟大學(xué)建筑設(shè)計研究院，上海 200092)［摘要］鐵嶺體育館工程是局部帶有大懸挑平臺的單層網(wǎng)殼結(jié)構(gòu)工程。介紹了大跨度網(wǎng)殼的結(jié)構(gòu)布置特點、靜力性態(tài)分析、動力響應(yīng)分析與非線性屈曲分析，同時給出鼓形節(jié)點的計算結(jié)果。結(jié)構(gòu)前方有近7m的大懸挑平臺且平臺端部荷載較重，采用預(yù)應(yīng)力懸挑梁+鋼管混凝土斜柱方式承擔大懸挑彎矩作用。分析方法、結(jié)果及設(shè)計方法可供類似結(jié)構(gòu)的分析、設(shè)計參考。［關(guān)鍵詞］單層網(wǎng)殼；動力響應(yīng)分析；非線性屈曲分析；大懸挑結(jié)構(gòu)Structure Design of Steel Roof and a Large Overhang Platform in Tieling GymnasiumJin Gang,Lu Xiuli,Ding Jiemin,Wu Honglei,Yang Haitao (Architectural Design & Research Institute of Tongji University,Shanghai 200092,China)Abstract:The Tieling Gymnasium is a steel single-layer shell structure with a large overhang platform. Designs of steel shell structure,the linear analysis,the dynamical response analysis,nonlinear stability analysis,the analysis result of shell structure joint are presented. There is a large overhang platform in this structure which is loaded with the steel shell structure. The bending of this platform is beared by steel tubular column and prestressed concrete beam. The analysis method and result can be taken as reference to similar structures.Keywords:single-layer shell structure; dynamical response; analysis; nonlinear stability; large overhang platform參考文獻［1］沈祖炎，陳揚驥. 網(wǎng)架與網(wǎng)殼［M］. 上海：同濟大學(xué)出版社，1997.
