摘要
国家体育馆屋盖结构为双向张弦网格结构体系。为保证屋盖结构在奥运期间和今后正常使用期间安全服役,在屋盖结构系统中引入了永久健康监测系统。该监测系统包括监测仪器、数据采集系统和数据分析与处理软件三部分,可以随时对屋盖结构的受力性能、变形状态进行监测。此外,介绍健康监测系统性能,包括稳定性、抗干扰性和远程监控。并分析钢结构变形、索力和应力监测结果。监测结果表明国家体育馆健康监测系统技术先进,稳定可靠。
The steel roof structure system of National Indoor Stadium is bidirectional truss string structure. To ensure the safety of the roof structure system in Olympics and for the future service, the permanent health monitoring system is imported. The monitoring system includes monitoring instrument, data-taker and data analysis software. The strength performance and distortion state of the roof structure could be monitored by the monitoring system at any moment. Besides, the performances of health monitoring system are introduced including stability, noise immunity and remote monitoring. The results of deformation, cable force and stress are analyzed. It presents the monitoring system of National Indoor Stadium is advanced and reliable.
