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 compression-bending and thrust structure.
- 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
- Warren Truss: Features alternating diagonals in a zigzag pattern with vertical support members
- Howe Truss: Utilizes diagonal members sloping away from the span center with vertical supports
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 supports transverse forces and enhances torsional stiffness.
Comprising longitudinal beams and connections that transfer loads from the deck to the main truss through a defined force path.
The walking surface for vehicles and pedestrians, similar in form to steel beam and combined beam bridges.
Simple structure with fixed design, easy to manufacture and install.
Features multiple bar specifications with large internal forces in vertical rods and all large nodes.
Distributes shear force across two diagonal rods, suitable for mounting/dismounting bridges with complex structure for small/medium spans.
Ideal for large spans with short compression rods that enhance buckling stability and simplify joint plate arrangements.
