Live loads such as vehicles and people, as well as constant loads such as the dead weight of the bridge, are first transmitted from the deck to the longitudinal beams and beams, and then converged to the main beams. The main beam transfers the load in the form of bending and shearing to the piers and abutments, and finally to the foundation. In this process, the high strength characteristics of steel enable the structure to withstand loads efficiently. By reasonably designing the mechanical model and member size of the structure, the stress of each component under different load conditions is ensured to be within a safe range.

Product Advantages

Steel structures have low density and are much lighter than concrete bridges under the same bearing requirements. This reduces the requirements for foundation bearing capacity, reduces the scale and cost of foundation projects, and facilitates transportation and installation in areas with complex terrain and difficult construction.

Product Application

Cross-river and cross-river bridges: Like Shanghai Nanpu Bridge, it adopts the form of a steel structure cable-stayed bridge connecting Pudong and Puxi. It is an important transportation hub in the city, greatly alleviating cross-strait traffic pressure and promoting interregional exchanges and development.
