The complicated structural relationships among the various substructures lead to difficulty in structural calculation and analysis. Detailed calculation for this structure, and analysis of the features and actions among the various substructures of the roof structure have been performed with software ANSYS. The results suggest that the forces acting on the structure are reasonable and the various substructures are able to coordinate with each other. The structural calculation has been proved correct through node tests and monitoring during construction.Keywords:spatial shell-string structure; prestress cable; nonlinear; wind-sensitive structure; construction monitoring作者简介:张达生,教授级高级工程师,一级注册结构工程师,Email:zzhangdasheng@163.com。参考文献[1]蔡元奇,朱以文,郭必武,等. 武汉体育中心体育馆张弦网壳屋盖优化、稳定及抗震性能研究[R].武汉:2005.[2]JGJ61—2003网壳结构技术规程[S]. 北京:中国建筑工业出版社,2003.[3]华中科技大学工程结构检测中心. 武汉体育中心二期体育馆钢结构节点试验[R]. 武汉:2006.[4]华中科技大学工程结构检测中心. 武汉体育中心二期体育馆钢结构安装监测[R]. 武汉:2006.
