N2 - In order to understand the dynamic characteristics of a cable-stayed bridge, field measurements of the traffic loadings and wind-induced response of the bridge using wireless technology have been carried out. Conventional field measurement systems employ cables for measurement transfer, and collect data at a single server for centralized processing. A major drawback of these systems is their installation time and costs can be very high. To solve the key problem of theses systems, a highly cost-effective wireless sensor network system for structural data acquisition is proposed in this paper. The system integrated with wireless sensing communication, computation, data management and data remote access via wireless local area network (WLAN). The performance of the system is validated in the field using a newly constructed Sifangtai cable-stayed bridge over the Song Hua Jiang River, Harbin, China. Both time domain data and Fourier transformed frequency domain analysis techniques were used to examine the structural response. The proposed system is shown to be effective for measuring the structure dynamic properties.
