Keywords: beam inclination; bridge; monitoring; rehabilitation
Abstract:On the morning of 23 May 2016, a traffic accident happened in the Middle Ring Road between the ramps of Zhenhua Road and Wanrong Road Shanghai, China. A series of on-the-spot tests are carried out and a real-time wireless sensor system is deployed in the bridge. The beam state is reasonably estimated according to the monitoring measurements and the rehabilitation is carried out through 28 steps. Health monitoring measurements show that the beam inclination is below 0.2°, and the beam stays in a stable state after traffic is resumed, which indicates that the repair has met the expected requirements.
