朝阳体育馆是亚运会工程之一。体育馆屋盖采用了预应力索—拱、索网结构。本工程为多样化的空间结构形式,在满足体育馆功能前提下创造新颖的建筑造型方面作了一些探索。文中介绍了设计的基本原则、构件截面、屋盖结构用钢量、节点构造、锚具、空心钢球、钢绞线防腐、预应力张拉、构件计算分析以及施工中的一些经验等。
Chaoyang Stadium is one of the projects of the Asian Games. The gymnasium roof adopts prestressed cable-arch and cable net structures. This project is a diversified spatial structure, and some explorations have been made to create novel architectural shapes under the premise of meeting the functions of the stadium. The basic principles of design, cross-sections of components, the amount of steel used in the roof structure, joint construction, anchorages, hollow steel balls, steel wire anticorrosion, prestressed tensioning, calculation and analysis of components, and some experiences in construction are introduced.
