摘要
杭州江干区全民健身中心属综合性体育建筑,功能较为复杂。结构设计为满足建筑的要求,重点解决了超长结构地下室基础的沉降控制及无缝设计,对上部结构进行了温度场作用下的非线性有限元分析,并采用沿纵向设置无粘结预应力筋等方法控制温度变形。还介绍了屋盖管桁架结构及其高低部位的连接处理。
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 ovedength 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 highlow position are introduced.
