（廣東省建筑設(shè)計研究院，廣州 510010）［摘要］廣州自行車館為2010年亞運會的主要比賽場館，屋蓋采用局部雙層的單層橢圓球面網(wǎng)殼結(jié)構(gòu)。網(wǎng)殼通過可徑向滑動球鉸支座與下部混凝土結(jié)構(gòu)連接，網(wǎng)殼周邊設(shè)置封閉環(huán)形約束桁架，中間單層殼體部分利用建筑凸肋造型設(shè)置加勁桁架，解決了保證整體穩(wěn)定和減小溫度應(yīng)力之間的矛盾，同時避免了網(wǎng)殼側(cè)推力直接傳遞給下部混凝土結(jié)構(gòu)，簡化了網(wǎng)殼支座及下部混凝土結(jié)構(gòu)的設(shè)計，節(jié)約了混凝土結(jié)構(gòu)的造價。［關(guān)鍵詞］自行車館；網(wǎng)殼；滑動球鉸支座；環(huán)形約束桁架；加勁桁架Structural design of Bicycle Stadium for the 2010 Asian GamesLiao Xuzhao(The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010,China)Abstract:Guangzhou Bicycle Stadium is a main venue for the 2010 Asian Games, the roof of which is a single-layer ellipsoid reticulated shell with partial double layers. The reticulated shell connects concrete structure in lower through spherical joint bearings which can slip along the radial. The closed ring confining truss is set along the periphery of the reticulated shell, and the stiffening truss is set in the middle single-layer shell which can take advantage of the architectural shape. These measures resolve the contradiction between overall stability and temperature stress, and also avoid the shell thrust act on the lower concrete structure directly. Besides, these measures simplify the design of the shell bearing and the concrete structure, and the cost of the concrete structure can also be saved.Keywords:Bicycle Stadium； reticulated shell; sliping spherical joint bearing； ring confining truss； stiffening truss作者簡介：廖旭釗，高級工程師，一級注冊結(jié)構(gòu)工程師。參考文獻［1］張相庭. 工程抗風(fēng)設(shè)計計算手冊［M］.北京：中國建筑工業(yè)出版社，1998［2］王鐵夢. 工程結(jié)構(gòu)裂縫控制［M］.北京：中國建筑工業(yè)出版社，2000［3］宋曼華，柴昶，武人岱. 鋼結(jié)構(gòu)設(shè)計與計算［M］.北京：機械工業(yè)出版社，1999［4］PACKER J A，等. 空心管結(jié)構(gòu)連接設(shè)計指南（中譯本）［M］. 北京：科學(xué)出版社，1997.［5］陳務(wù)軍，董石麟，付功義. 大型局部雙層網(wǎng)殼的體系及穩(wěn)定性研究［J］. 建筑結(jié)構(gòu)學(xué)報，2005，26(1)
