The steel truss bridge utilizes a framework of interconnected steel bars arranged in triangular patterns to provide exceptional strength and stiffness. This prefabricated solution offers fast installation and delivery, making it ideal for various bridge applications.

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.

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 and connections that transfer loads from the deck to the main truss through a systematic force transmission path.

The walking surface for vehicles and pedestrians, designed similarly to steel beam bridges with composite construction.

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, creating shorter sections ideal for mounting/dismounting bridges.

Utilizes two diagonal rods per node, beneficial for large spans with short compression rods that enhance buckling stability.

• Pratt Truss Bridge: Diagonal members slope toward the span center with vertical members in tension, ideal for medium-to-long spans.
• Howe Truss Bridge: Diagonal members slope outward from the center, historically popular for railway bridges.

• Highway and road bridges for various span lengths
• Pedestrian bridges
• Railway crossings
