In order to study the change in performance of the Suifenhe cable-stayed bridge in China over 12 years, cable force, elevation, static and dynamic load tests were conducted in 2006 and 2018, respectively. In this paper, theoretical data, obtained through finite element model analysis, were compared with the measured load test data for changes in static and dynamic performances. A comparison between 2006 and 2018 shows that additional dead load deflection exists in the main span after 12 years of operation. And that the cable force due to dead load of the full-scale cable-stayed bridge decreases and redistributes, which have adverse effects on the safety of bridge structure after long-term operations. Therefore, on-site inspection, static and dynamic load tests are recommended for cable-stayed bridges over 10-years old to test their static and dynamic performance. Moreover, cable force adjustments are to be conducted whenever necessary for the cable-stayed bridge used swivel construction.
