Product Description
Steel Cable Suspension Bridge Overview
A flexible suspension combination system composed of main cable and stiffened beam with stress characteristics of both cable and beam. Most bridges with spans greater than 1000m utilize suspension bridge structures due to their superior load-bearing capacity.
Key Structural Components
Main Cable
Primary load-bearing component that deforms under load, directly affecting bridge internal force and deformation. Available in two types:
- Wire Rope Main Cable: 7-strand construction for small span bridges
- Parallel Wire Bundle Main Cable: Prefabricated parallel steel wire strand (PPWS method) for accelerated construction
Bridge Tower
Main load-bearing component resisting vertical loads. Available in multiple structural forms:
- Rigid Tower: Minimal horizontal displacement at top
- Flexible Tower: Significant horizontal displacement at top
- Rocking Column Tower: Hinged single-column for small spans
Stiffening Beam
Secondary structure ensuring vehicle running and providing structural stiffness, mainly bearing bending internal force.
Sling & Anchorage Systems
Sling materials include steel wire rope, parallel steel wire bundle, or steel strand. Anchorage options include gravity anchorage and tunnel anchorage for optimal foundation transfer.
Bridge Classification
By Suspension Span
- Single-span suspension bridge
- Three-span suspension bridge
- Four-span suspension bridge
- Five-span suspension bridge
By Main Cable Anchoring
- Ground Anchorage: Tension transferred to foundation via gravity or tunnel anchorage
- Self-Anchoring: Tension transmitted directly to stiffening beam
