摘要
常州体育会展中心由体育馆会展中心、体育场、游泳馆等组成。其中体育馆屋盖采用了索承单层网壳结构,该网壳不但跨度较大,而且是国内外同类结构中唯一的椭圆形穹顶,相比正圆形索承单层网壳,椭圆形具有各向受力不对称,设计、施工难度更大等特点。介绍了该屋盖的结构选型,椭圆形索承单层网壳结构布置、构件截面等结构设计基本情况,静力、动力和稳定性分析内容,以及屋盖整体缩尺模型和节点试验及施工模拟分析情况,最后简单介绍了会展中心及体育用品商店入口单层网壳结构的设计情况。
Changzhou Sports and Exhibition Center is composed of a gymnasium and exhibition center,a stadium and a swimming gym.A cable-supported dome is employed as the roof structure of the gym.This cable-supported dome is not only a large span structure,but also the only elliptical cable-supported dome constructed in domestic and overseas.Compared with round domes,elliptical domes have asymmetry force and bear more difficulties in design and construction.The structure comparison,geometric layout,member arrangement and section selection were described. It also introduced contents of static and dynamic analysis,buckling and nonlinear static analysis,tests of an integral model and connections,and simulation of its construction procedure.Finally,the structural design of the exhibition center and a sports shop's single layer shell were introduced briefly.
