Product Description
Structural Design & Classification
Steel arch bridges utilize arch structures primarily made of steel to efficiently distribute traffic loads and forces to bridge supports. These structures are known for exceptional strength, durability, and environmental sustainability through steel recyclability.
Structural Classification Systems
By Main Arch Ring Section:
- Steel Box Arch
- Steel Pipe Arch
- Steel Truss Arch
By Structural System:
- Simple System Arch Bridge - Arch ring bears all forces with thrust handled by piers/foundations
- Combined System Arch Bridge - Carriageway beam and arch work together in load distribution
Key Structural Components
Arch Rib
Primary load-bearing member that mainly withstands axial pressure. Available in box, pipe, and truss configurations, with truss arches offering superior span capacity and economic efficiency.
Boom System
Transfers deck loads to arch ribs. Available as rigid booms (steel pipe/section steel) or flexible booms (high-strength steel wire bundles).
Tie Bar/Beam
Handles arch thrust in non-thrust arch designs, bearing significant axial tension forces.
Cross Brace
Ensures transverse stiffness and stability, with configurations including one-word, K-shaped, X-shaped, and meter-shaped braces.
