Seven key measures in the "Guiding Opinions"

The Ministry of Transport issued the “Guiding Opinions to Promote Road Construction of Steel Structure Bridges” (called “Guiding Opinions”) and decided to promote the construction of steel frame beams, steel truss beams, core tube composite beams and other high-speed road steel structure bridges to improve roads. The quality of the bridge. Give full play to the performance advantages of steel structure bridges and promote the transformation and upgrading of road construction.

The "Guiding Opinions" put forward 7 key measures.

One is to strengthen the comparison of alternatives and encourage the use of steel bridges. Starting from the engineering feasibility study stage, comprehensively consider factors such as bridge construction cost, safety and durability, management and maintenance, strengthen the comparison and selection of concrete bridges and steel structure bridges, and encourage the choice of steel structure bridges.

The second is to make reasonable model selection to better utilize the advantages of steel structure bridges. The selection of the bridge structure is comprehensively determined according to the use function of the bridge and the local environment.

The third is the structural design of the steel bridge. Promote the use of weathering steel in projects with suitable environmental conditions to improve the corrosion resistance of the structure in the natural environment and reduce maintenance costs.

The fourth is to comprehensively improve the maintainability of the structure. The bridge design fully considers the functional requirements of later management and maintenance, and improves the maintenance structure measures to make it accessible, checkable, repairable and replaceable, and improve the convenience and safety of daily maintenance work.

The fifth is to promote the industrialization, standardization and intelligent construction of steel structure bridges. Vigorously promote the standardized design, industrialized production and prefabricated construction of steel structure bridge construction to improve the quality of bridge engineering.

Sixth, improve relevant standard indicators. Seriously summarize the implementation of the current technical standards for steel structure bridges and the experience in construction, management, and maintenance, and timely revise and improve relevant standards and specifications in response to problems arising from the promotion and use of steel structure bridges.

Seven is to strengthen the training of professional talents. Encourage universities, scientific research, design, manufacturing, installation, management and other units to strengthen the introduction and training of steel structure professionals. Prefabricated building
