The steel truss bridge is a structural system between beams and arches. It is a structure in which a bent upper beam structure and a pressure-bearing lower column are integrated together. Due to the rigid connection between the beam and the column, the beam is unloaded due to the flexural rigidity of the column. The entire system is a compression-bending structure as well as a thrust structure.

Main Components: Main girder, Bracing, Bridge deck system, Bridge floor

Classification: Upper bearing steel truss bridge (bridge floor in upper part) and lower bearing steel truss bridge (bridge floor in lower part).

The main load-bearing structure that bears vertical loads. Composed of:

• Upper chord
• Lower chord
• Belly rod (divided into diagonal bar and vertical bar)

Classification: Longitudinal connection and horizontal connection

Function: Connects the main truss to form a stable space structure capable of withstanding various lateral loads.

Composition: The longitudinal beam, beam and the connection between the longitudinal beam.

Force transmission: Load → longitudinal beam → beam → main truss.

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

Simple structure, fixed design, easy to install and manufacture.

Features multiple bar specifications and large internal force of the vertical rod.

Shear force borne by two diagonal rods, suitable for small/medium spans with complex structure or large spans with short, light rods.

Shear force borne by two diagonal rods, ideal for large spans with short compression rods that enhance buckling stability.
