Product Description
Steel Truss Bridge Overview
Steel truss bridges represent a structural system that combines beam and arch principles, featuring integrated upper beam structures and pressure-bearing lower columns. The rigid connection between beam and column provides exceptional stiffness and load distribution capabilities.
Structural Components
Main Girder
The primary load-bearing structure that supports vertical loads. Composed of upper chord, lower chord, and belly rod elements including diagonal and vertical bars.
Bracing Systems
- Longitudinal connections: Upper and lower horizontal systems that withstand transverse loads including wind and centrifugal forces
- Transverse connections: Bridge frames and crosslinks that enhance torsional stiffness and distribute loads evenly
Bridge Deck System
Comprising longitudinal beams and cross beams that transfer loads from the deck to the main truss structure.
Bridge Deck
The surface layer designed for vehicle and pedestrian traffic, compatible with various bridge types.
Truss Configuration Types
Triangular Truss
Simple structure with fixed design parameters, offering easy installation and manufacturing efficiency.
Diagonal Bar Truss
Features multiple bar specifications with significant vertical rod internal forces, utilizing large nodes throughout the structure.
K-Shaped Truss
Distributes shear forces across two diagonal rods per node, creating shorter sections. Complex structure suitable for small to medium spans, ideal for modular bridge applications.
Double-Vented Bar Truss
Utilizes two diagonal rods per node to handle shear forces, featuring short compression rods that enhance buckling stability. Particularly effective for large-span applications.
