| Abstract | The Seohae cable-stayed bridge, a 990-m long composite cable-stayed bridge, had a structural health monitoring system (SHMS) that was designed in the design and construction stage. The SHMS for the bridge was renovated in 2009. One of the main features of the renovation project was the installation of the global navigation satellite system (GNSS) to improve the disadvantages and limitations of traditional sensors. Based on the GNSS and SHMS monitoring, the long-term displacements and dynamic characteristics of the bridge were evaluated in this paper. Using the least-squares method to fit the temperaturedisplacement relationship, the measured variation rate of displacement to temperature was obtained and compared with the theoretical value. Dynamic characteristics such as the natural frequencies and mode shapes have been successfully extracted from the GNSS signals. |
