Research on Durability Preventative Maintenance Technology of Steel Plate Composite Beam Bridges with Small and Medium Span: Review

The steel plate composite beam bridge is the main form of steel bridge with small and medium span. There are myriad problems with the corresponding maintenance technology, especially preventative maintenance. However, there are limited studies on this technology and its applications in China. Based on domestic and overseas research, preventative maintenance in the U.S. is introduced, and the problems of bridge maintenance in China are addressed. The main forms, principles, and treatment of diseases on steel plate composite beam with small and medium span are acknowledged. Finally, the principle of durability in preventative maintenance is promoted and a case analysis is conducted. The maintenance technology proposed in this paper could be a reference for preventative maintenance of steel plate composite beam bridges with small and medium span in China.
