China Bridge Steel Plate

The corrosion mechanism of weathering steel under the coupling of environment and load, the degradation of mechanical properties of weathering steel after corrosion, the design theory and detailed design method of weathering steel bridge and other contents are mainly described in the Chinese bridge steel plate, and the achievements and remaining problems of existing research are summarized and analyzed. The degradation of mechanical properties is more serious; The detailed design method of steel bridge is very important to ensure the corrosion resistance of weathering steel, and regular maintenance can prolong the service life of the structure; The application of weathering steel can significantly reduce the life cycle cost of steel bridges. The analysis results are intended to provide a clear direction for the future research on the corrosion resistance mechanism and mechanical properties of weathering steel in China, and provide reference for the design and construction of weathering steel bridges in China.
