The steel truss bridge utilizes a framework of steel trusses to support the bridge deck, consisting of interconnected bars or beams arranged in a triangular pattern for excellent strength and stiffness. These bridges are renowned for their durability, versatility, and rapid installation capabilities.
The primary load-bearing structure composed of upper chord, lower chord, and belly rod (including diagonal and vertical bars). Nodes are categorized into large and small nodes with defined pitch distances.
Classified into longitudinal and horizontal connections that stabilize the structure against lateral loads. The system includes upper and lower horizontal longitudinal connections to withstand transverse forces and reduce chord free length.
Comprising longitudinal beams, transverse beams, and their connections. Load distribution flows from longitudinal beams to transverse beams, then to the main truss.
The walking surface for vehicles and pedestrians, designed similarly to steel beam and combined beam bridges.
Simple structure with fixed design, facilitating easy installation and manufacturing.
Features multiple bar specifications with significant vertical rod internal forces and large nodes.
Distributes shear force across two diagonal rods, creating shorter sections ideal for mounting/dismounting bridges in small to medium spans.
Optimized for large spans with short compression rods that enhance buckling stability and simplify joint plate arrangements.
- Structural Appearance: Distinctive lattice-like framework of triangular steel units
- Material Properties: High-strength steel with excellent tensile/compressive strength and ductility
- Modular Construction: Factory-fabricated components for quality control and rapid assembly
- High Strength-to-Weight Ratio: Capable of long spans while remaining relatively lightweight
