Product Description
Steel Cable Suspension Bridge Overview
Steel cable suspension bridges are flexible suspension systems combining main cables and stiffened beams, featuring the stress characteristics of both cable and beam structures. These bridges are ideal for spans exceeding 1000m and consist of bridge towers, main cables, slings, stiffening beams, anchors, and saddles.
Structural Components
Main Cable Systems
The main cable is the primary load-bearing component that transmits forces from slings to anchors, piers, and towers. Available in two types:
- Wire Rope Main Cable: 7-strand construction for smaller span bridges
- Parallel Wire Bundle Main Cable: Prefabricated parallel steel wire strand (PPWS) method for accelerated construction
Bridge Tower Systems
Bridge towers resist vertical loads and are available in multiple configurations:
- Structural Forms: Rigid tower, flexible tower, and rocking column tower
- Cross Bridge Forms: Truss type, rigid frame type, and mixed type structures
Stiffening Beam Options
Multiple beam types available including steel truss beams, steel box beams, concrete beams, and steel-mixed composite beams
Technical Specifications
Load Distribution
Loads are transmitted from slings to cables, then to anchors, piers, and towers. Both main cables and stiffened beams share the load-bearing function.
Anchorage Systems
Two primary anchorage types:
- Gravity Anchorage: Suitable for all conditions with concrete anchor body construction
- Tunnel Anchorage: Economical option with reduced concrete consumption for suitable geological conditions
Bridge Classification
By Suspension Span
- 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
- Self-Anchoring: Main cable tension transmitted directly to stiffening beam
