Product Description
Large Span Steel Arch Bridge Overview
Our performance large span steel arch bridges feature painted surfaces and are engineered for exceptional strength, durability, and aesthetic appeal. These bridges efficiently distribute traffic loads and environmental forces to abutments or piers through their optimized arch structure.
Structural Design & Classification
Arch Rib Types
- Steel box arch - Robust section design for heavy loads
- Steel pipe arch - Circular sections for efficient material use
- Steel truss arch - Lightweight with superior span capacity
Carriageway Positioning
- Upper bearing type - Deck above arch structure
- Middle bearing type - Deck integrated within arch
- Lower bearing type - Deck suspended below arch
Key Structural Components
Arch Rib
Primary load-bearing member designed to withstand axial compression and bending moments. Available in box, pipe, or truss configurations for optimal performance.
Boom Systems
Force transfer components that transmit deck loads to arch ribs. Available as rigid booms (steel pipe/section) or flexible booms (high-strength steel wire).
Tie Bars & Cross Bracing
- Tie bars absorb arch thrust in non-thrust configurations
- Cross bracing enhances transverse stiffness and stability
- Multiple brace types available: one-word, K-shaped, X-shaped, meter-shaped
Technical Specifications
