What Does Rocker Bearing Issues Mean?
Currently, the bearings of Poyanghu Bridge, a 636-meter long cable-stayed bridge, have actually been damaged. According to numerical analyses, the mechanical state of the damaged bridge unfavorably differs the perfect design state, and the bridge ought to be fixed in time to restore its safety and serviceability. Nevertheless, compared to the bearing repair of beam bridges, much less clinical and engineering endeavors have actually been made in the history to direct the bearing repair work of cable-stayed bridges.
Through these works, it is discovered that the proposed repair work plans work in useful usage. 1. hydraulic torque wrench , Bearing damages are typical structure illness for bridges in operation. If they are not repaired in time, the health of the bridges might be threatened. For bearing repair work of beam bridges, the jack-up approach is normally used.
A lot of scientific research studies and engineering applications suggest that the jack-up method is fully grown and appropriate to bearing repair work of beam bridges [15] Under functional loads and environmental rusts, the bearing damages can also be found on cable-stayed bridges. Nevertheless, different from beam bridges, when the bearings on cable-stayed bridges stop working, the primary girders will be raised by the stayed cables near the damaged bearings, leading to the harmful scenarios in which the main girders and the bearings are separated.
Nevertheless, compared to the bearing repair of beam bridges, much less scientific research study studies or engineering undertakings have actually been devoted to the bearing repair work of cable-stayed bridges to the writers' understanding. In July, 2019, bearing damages were observed on Poyanghu Bridge, a 636-meter long cable-stayed bridge. To fix the bearings, 2 innovative repair work schemes were proposed by practicing engineers, which are reported and numerically validated in this article.

This article likewise reports the on-location tracking of the bearing repair of Poyanghu Cable-stayed Bridge. Various from tracking of the bearing repair of beam bridges which normally focuses on the displacements of the beams near the bearings [13], the present tracking practice measured the forces of some remained cable televisions in contrast with the computed arise from mathematical designs.
