［摘要］杭州江干區(qū)全民健身中心屬綜合性體育建筑，功能較為復(fù)雜。結(jié)構(gòu)設(shè)計為滿足建筑的要求，重點(diǎn)解決了超長結(jié)構(gòu)地下室基礎(chǔ)的沉降控制及無縫設(shè)計，對上部結(jié)構(gòu)進(jìn)行了溫度場作用下的非線性有限元分析，并采用沿縱向設(shè)置無粘結(jié)預(yù)應(yīng)力筋等方法控制溫度變形。還介紹了屋蓋管桁架結(jié)構(gòu)及其高低部位的連接處理。

Abstract:The National Fitness Center in Jianggan district of Hangzhou is a comprehensive sports construction with complex function. In order to satisfy the need of the architecture, structural design resolves the foundation settlement control and the seamless floor design of overlength basement structure. The non-linear FEM to the superstructure under temperature load has been carried out. After the FEM analysis,several methods like setting prestress steel bar without bond along longitudinal direction are adopted to control the temperature deformation. The tube truss system of the roof structure and the connecting processing of high-low position are introduced.

Keywords:overlength construction；prestressed beam；tube truss system
