The steel structure can be processed into various steel structure bridges, including steel truss bridges. A steel truss bridge is a structural system between beams and arches, integrating a bent upper beam structure with pressure-bearing lower columns. This rigid connection creates a compression-bending and thrust structure system.

• Upper bearing steel truss bridge: Bridge floor located in the upper part of the main truss
• Lower bearing steel truss bridge: Bridge floor located in the lower part of the main truss

The primary load-bearing structure composed of upper chord, lower chord, and belly rod (including diagonal and vertical bars). Nodes are classified as large or small nodes, with pitch referring to the distance between nodes.

• Classification: Longitudinal connection and horizontal connection
• Function: Connects main trusses to form a stable space structure capable of withstanding lateral loads
• Longitudinal connection systems (upper and lower horizontal) withstand transverse loads and reduce chord free length
• Transverse connections (bridge frame and crosslink) increase torsional stiffness and adjust force distribution

Composed of longitudinal beams, beams, and their connections. Load transfer path: from longitudinal beams to beams, then to main trusses.

The walking surface for vehicles and pedestrians, with forms similar to steel beam bridges and combined beam bridges.
