Structural Health Monitoring System Developed for Dalian Stadium

The peripheral structure of Dalian stadium is a long-span spatial truss structure. To ensure the safety of the peripheral structure during construction and operation period, the permanent structure health monitoring system is implemented. This paper first introduces the structural features of the Dalian stadium, and then illustrates the permanent monitoring program from the aspects of the hardware, the monitoring scheme and the function. This developed monitoring system is utilized to monitor the stress of the truss, and the dynamic response of the structure. Large amounts of data are obtained through the health monitoring system, and thus the safe condition of the structure can be evaluated based on data analysis.
