The steel truss bridge is a structural system between beams and arches, combining a bent upper beam structure with pressure-bearing lower columns in an integrated design. This rigid connection creates a compression-bending and thrust structure that efficiently distributes loads.

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

Includes longitudinal and horizontal connections that stabilize the structure against lateral loads. The system connects main trusses to form a robust space structure resistant to wind, rocking forces, and torsion.

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

The walking surface for vehicles and pedestrians, available in upper or lower bearing configurations relative to the main truss.
