（1 武漢市建筑設(shè)計(jì)院，武漢 430014； 2 武漢大學(xué)土木建筑工程學(xué)院，武漢 430072）［摘要］武漢體育中心二期體育館工程屋蓋結(jié)構(gòu)是一個由扁平網(wǎng)殼、空間拱桁架及空間索系構(gòu)成的新型空間組合結(jié)構(gòu)，結(jié)構(gòu)中各個子結(jié)構(gòu)關(guān)系復(fù)雜，計(jì)算分析難度大。采用ANSYS軟件進(jìn)行了詳細(xì)計(jì)算，對屋蓋結(jié)構(gòu)的特點(diǎn)以及各個子結(jié)構(gòu)的作用進(jìn)行了分析，結(jié)果顯示，該結(jié)構(gòu)受力合理，各個子結(jié)構(gòu)具有很強(qiáng)的協(xié)同工作能力。通過節(jié)點(diǎn)試驗(yàn)及施工監(jiān)測，驗(yàn)證了結(jié)構(gòu)計(jì)算的正確性。［關(guān)鍵詞］空間張弦網(wǎng)殼；預(yù)應(yīng)力索；非線性；風(fēng)敏感結(jié)構(gòu)；施工監(jiān)測Design of the roof shell-string structure in Wuhan Sports Center (Phase Ⅱ)Zhang Dasheng1，Guo Biwu1，Cai Yuanqi2，Zong Jing1，Yuan Qiang1，Yuan Chen1(1 Wuhan Architectural Design Institute, Wuhan 430014, China；2 School of Civil Engineering，Wuhan University，Wuhan 430072, China)Abstract:The roof structure of Phase II Gymnasium project of Wuhan Sports Center is a new-type spatial composite structure consisting of a flat net shell, spatial arch trusses and spatial cable-stayed systems. The complicated structural relationships among the various substructures lead to difficulty in structural calculation and analysis. Detailed calculation for this structure, and analysis of the features and actions among the various substructures of the roof structure have been performed with software ANSYS. The results suggest that the forces acting on the structure are reasonable and the various substructures are able to coordinate with each other. The structural calculation has been proved correct through node tests and monitoring during construction.Keywords:spatial shell-string structure； prestress cable； nonlinear； wind-sensitive structure； construction monitoring作者簡介：張達(dá)生，教授級高級工程師，一級注冊結(jié)構(gòu)工程師，Email:zzhangdasheng@163.com。參考文獻(xiàn)［1］蔡元奇，朱以文，郭必武，等. 武漢體育中心體育館張弦網(wǎng)殼屋蓋優(yōu)化、穩(wěn)定及抗震性能研究［R］.武漢：2005.［2］JGJ61—2003網(wǎng)殼結(jié)構(gòu)技術(shù)規(guī)程［S］. 北京：中國建筑工業(yè)出版社，2003.［3］華中科技大學(xué)工程結(jié)構(gòu)檢測中心. 武漢體育中心二期體育館鋼結(jié)構(gòu)節(jié)點(diǎn)試驗(yàn)［R］. 武漢：2006.［4］華中科技大學(xué)工程結(jié)構(gòu)檢測中心. 武漢體育中心二期體育館鋼結(jié)構(gòu)安裝監(jiān)測［R］. 武漢：2006.
