摘要
杭州2022年第19届亚运会板球场馆主体采用了钢框架的结构形式,其大悬挑屋盖采用了空间网格结构。因功能及平面布局较为复杂,故采用了YJK、PKPM和MIDAS等多种软件对主体结构进行了整体协同分析和对比计算。通过弹性及弹塑性分析计算,所得的各项指标均满足规范要求,结构选型合理、安全可靠;针对楼盖进行了舒适度分析,对复杂节点进行了有限元分析,并采取了必要的加强措施;大悬挑屋盖结构的抗风设计,采用了基于CFD的数值模拟分析数据作为参考,作为荷载规范的补充依据。
The main body of the cricket stadium for the 19th Asian Games in Hangzhou in 2022 adopts a steel frame structure,and its large cantilevered roof adopts a spatial grid structure.Due to the complex functions and plane layout,various software such as YJK,PKPM,and MIDAS have been used to conduct overall collaborative analysis and comparative calculation of the main structure.Through elastic and elastoplastic analysis and calculation,all indicators obtained meet the requirements of the specification,and the structure selection is reasonable,safe and reliable;The comfort analysis of the floor and the finite element analysis of the complex joints are carried out,and necessary strengthening measures are taken;The wind resistance design of large cantilevered roof structures uses CFD based numerical simulation analysis data as a reference,as a supplementary basis for the load code.
