Efficient Construction Process Metal Truss Bridge For Railway Transportation

The steel truss bridge is a structural system between beams and arches, widely utilized in civil engineering. It combines a bent upper beam structure with pressure-bearing lower columns integrated together, forming a compression-bending and thrust structure.

The primary load-bearing structure composed of upper chord, lower chord, and belly rod (diagonal and vertical bars). Nodes are categorized as large or small with defined pitch distances.

Includes longitudinal and horizontal connections that stabilize the structure against lateral loads. The system connects main trusses to form a robust space structure capable of withstanding various forces.

Comprising longitudinal beams and connections that efficiently transfer loads from the deck to the main truss structure.

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

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

Features multiple bar specifications with significant internal forces in vertical rods.

Distributes shear forces through two diagonal rods, suitable for mounting/dismounting bridges.

Ideal for large spans with short compression rods that enhance buckling stability.

Ideal for urban bridges, highway viaducts, overpasses, and various span configurations including reinforced concrete, prestressed concrete, and rigid frame structures.
