Bridge Bearings - California Department of Transportation for Beginners

Currently, the bearings of Poyanghu Bridge, a 636-meter long cable-stayed bridge, have been harmed. According to mathematical analyses, the mechanical state of the damaged bridge unfavorably deviates from the perfect design state, and the bridge must be fixed in time to restore its safety and serviceability. However, compared to  Keep Checking Back Here  bearing repair of beam bridges, much less clinical and engineering ventures have actually been made in the history to direct the bearing repair work of cable-stayed bridges.

Through these works, it is found that the proposed repair work schemes are reliable in useful use. 1. Introduction, Bearing damages are typical structure diseases for bridges in operation. If they are not repaired in time, the health of the bridges might be endangered. For bearing repairs of beam bridges, the jack-up approach is typically utilized.

A great deal of clinical research studies and engineering applications recommend that the jack-up method is mature and appropriate to bearing repairs of beam bridges [15] Under functional loads and environmental corrosions, the bearing damages can likewise be identified on cable-stayed bridges. Nevertheless, different from beam bridges, when the bearings on cable-stayed bridges stop working, the primary girders will be lifted up by the remained cable televisions near the broken bearings, resulting in the dangerous scenarios in which the primary girders and the bearings are separated.

However, compared with the bearing repair of beam bridges, much less scientific research study studies or engineering ventures have actually been devoted to the bearing repair 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 repair the bearings, 2 innovative repair work plans were proposed by practicing engineers, which are reported and numerically verified in this short article.

How Performance of Elastomeric Bearings on MD Bridges can Save You Time, Stress, and Money.

This short article also reports the on-location monitoring of the bearing repair of Poyanghu Cable-stayed Bridge. Different from tracking of the bearing repair work of beam bridges which typically focuses on the displacements of the beams near the bearings [13], the present tracking practice measured the forces of some stayed cable televisions in comparison with the computed outcomes from numerical designs.
