The 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 with excellent load-bearing capabilities.

• Upper Bearing: Bridge floor located in the upper part of the main truss
• Lower Bearing: 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 (diagonal and vertical bars). Nodes are categorized as large or small with defined pitch distances.

• Longitudinal connection (upper/lower horizontal) withstands transverse loads
• Transverse connection (bridge frame/crosslink) increases torsional stiffness

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

The walking surface for vehicles and pedestrians, similar to steel beam bridge designs.

• Large span capability
• Fast construction speed
• High strength-to-weight ratio
• Attractive architectural appearance
• Customizable designs
• Durable and sustainable construction

Simple structure with fixed design for easy installation and manufacturing.

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

Distributes shear force across two diagonal rods, ideal for mounting/dismounting bridges.

Excellent for large spans with favorable buckling stability characteristics.
