The steel truss bridge is a structural system between beams and arches, combining a bent upper beam structure and pressure-bearing lower column into an integrated unit. This rigid connection creates a compression-bending and thrust structure that offers excellent load-bearing capabilities.
Based on bridge floor position:
- Upper bearing steel truss bridge: Bridge floor located above the main truss
- Lower bearing steel truss bridge: Bridge floor located below the main truss
Main Girder: 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.
Bracing: Includes longitudinal and horizontal connections that stabilize the structure against lateral loads. The system comprises:
- Longitudinal connection systems (upper and lower horizontal)
- Transverse connections (bridge frame and crosslink)
Bridge Deck System: Transfers loads through longitudinal beams to crossbeams and ultimately to the main truss.
Bridge Floor: The walking surface for vehicles and pedestrians, similar to other steel beam bridge designs.
Triangular Truss: Simple structure with fixed design for easy installation and manufacturing.
Diagonal Bar Truss: Features multiple bar specifications with large internal forces at vertical rods.
K-shaped Truss: Shear force distributed across two diagonal rods, ideal for mounting/dismounting bridges.
Double-vented Bar Truss: Features two diagonal rods sharing shear force, excellent for large spans with short compression rods.
Ideal for urban bridges, highway viaducts, overpasses, and various span configurations including reinforced concrete, prestressed concrete, and rigid frame structures.
- Versatile span lengths from short to long configurations
- Exceptional durability with corrosion-resistant materials
- Rapid construction capabilities
- Superior strength-to-weight ratio
- Cost-effective and sustainable solution
