According to the analyses of characteristics of each architectural element and layout, frame-shear wall structure and concrete bent frame for the main structure, cantilevered truss with suspended members for the roof, cable-strut self-balance structure for the glass curtain wall and large-area suspended steel grid structure for metal curtain wall were put forward . By modeling analyses, the main mechanical features of the main structure and each part of steel structure were attained. Results show that the key technical indicators, such as inter-story drift angle, shear-weight ratio, stiffness-weight ratio as well as structural displacement and member stress, can all meet the code requirements. The key joints which connect different parts of the structure were designed to ensure collaborative work of the whole structure.Keywords: gymnasium; structural system selection; structure analysis; suspended steel grid structure; cantilevered steel truss*天津市科技支撐計劃項目(13ZCZDSF01400)。作者簡介:閆翔宇,博士,高級工程師,一級注冊結(jié)構(gòu)工程師,Email: xy_yan2005@163.com。參考文獻[1]于敬海,毋英俊. 天津大學(xué)新體育館結(jié)構(gòu)設(shè)計[J].工業(yè)建筑,2008,38(增刊):250-254.[2]廖昕.創(chuàng)意與理性的思考——天津大學(xué)體育館設(shè)計[J].建筑學(xué)報,2011,58(8):66-67.[3]馬洪步,張琳,鮑蕾,等.杭州奧體中心體育游泳館結(jié)構(gòu)設(shè)計[J].建筑結(jié)構(gòu),2013,43(17):58-62.[4]毋英俊,陳志華.天津大學(xué)新體育館金屬幕墻體系設(shè)計[J].工業(yè)建筑,2008,38(增刊):255-260.[5]陳志華,田川,閆翔宇,等.天津大學(xué)新體育館點支式玻璃幕墻預(yù)應(yīng)力自平衡索桁架支撐體系設(shè)計分析[J].建筑鋼結(jié)構(gòu)進展,2012,14(1):21-26.[6]傅學(xué)怡,高穎,楊想兵,濟南奧體中心體育場大跨空間結(jié)構(gòu)總裝分析[J].建筑結(jié)構(gòu)學(xué)報,2008,29(增刊1):176-182.[7]田川.天津大學(xué)新體育館鋼結(jié)構(gòu)總裝整體協(xié)同作用分析[D].天津:天津大學(xué),2011.[8]毋英俊,陳志華.天津大學(xué)新體育館屋架與金屬幕墻體系節(jié)點選型[J].鋼結(jié)構(gòu),2008,38(增刊):455-460.
