Zhu Binghu' Li Dalin' (1.School of Civil Engineering.Tongji University Shanghai 200092 China: 2.Shanghai Tongji Construction Qualiry Inspection Station Shanghai 200092.China) Abstract:The application and research status of the health monitoring sensors in large span spatial structure are introduced emphatically.The method and principle of health monitoring for large span spatial structure are put forward.Then bined with the engineering practice the method of health monitoring is illustrated.Some ponents stress of the steel structure are monitored such as steel members cable membrane surface etc.Then the welding cracks are monitored.The monitoring results are obtained finally.The health monitoring about wind effect wind pressure and wind-induced vibration of the large span spatial structures are researched.The monitoring items corresponding sensors and methods as well as some engineering applications are presented.The further problems to be investigated and solved are listed. Key words:large span spatial stru...
