The H-shaped steel bridge GHB has a simple structure and meets the needs for replacing medium and small bridges.
The H-shaped steel bridge GHB is a product designed to meet the needs for replacement of medium and small bridges with span lengths of 10m to 25m, featuring a simple structure that utilizes large rolled H-shaped steel for the main girders and cross girders. Additionally, compared to conventional PC bridges, it can reduce the dead load of the superstructure, which alleviates the burden on existing substructures and offers advantages in terms of seismic resistance. In terms of design, it aims for standardization, enabling quick design responses and reductions in construction time and costs, while also considering improvements in corrosion resistance, fatigue resistance, and inspection workability.
