Product Description
Steel Cable Suspension Bridge Overview
A flexible suspension system combining main cable and stiffened beam components, designed for large-span applications exceeding 1000m. This structural solution offers optimal performance for major crossing requirements.
Structural Components & Load Distribution
Load transmission flows from sling to main cable, then to anchor, pier, and tower. Both main cable and stiffened beam share force distribution under external loads.
Key Structural Elements
- Main Cable: Primary load-bearing component under tension; available as wire rope (7-strand for smaller spans) or parallel wire bundle (PPWS method)
- Bridge Tower: Supports vertical loads; available as rigid, flexible, or rocking column configurations
- Stiffening Beam: Secondary structure ensuring vehicle operation and providing stiffness; types include steel truss, steel box, concrete, and composite beams
- Sling: Force transmission element connecting stiffened beam to main cable; materials include steel wire rope, parallel wire bundles, or steel strands
- Anchor: Structure anchoring main cable tension to foundation; gravity or tunnel anchor types
- Saddle: Critical component between main cable and tower top, distributing forces evenly
Suspension Bridge Classification
By Span Configuration
- Single-span suspension bridge
- Three-span suspension bridge
- Four-span suspension bridge
- Five-span suspension bridge
By Anchoring Method
- Ground anchorage: Main cable tension transferred to foundation via gravity or tunnel anchors
- Self-anchoring: Main cable tension transmitted directly to stiffening beam
