Product Description
Steel Cable Suspension Bridge Overview
A flexible suspension combination system composed of main cable and stiffened beam, combining stress characteristics of both cable and beam structures. This engineering solution is ideal for spans exceeding 1000 meters, offering superior load distribution and structural efficiency.
Key Structural Components
- Bridge Tower: Primary load-bearing component resisting vertical loads
- Main Cable: Core structural element bearing primary tension forces
- Sling: Force transmission component connecting stiffened beam to main cable
- Stiffening Beam: Secondary structure ensuring vehicle stability and providing structural stiffness
- Anchor: Structure anchoring main cable tension to foundation
- Saddle: Critical member supporting main cable at tower transitions
Load Distribution System
External loads transmit from sling to cable, then to anchor, pier, and tower. Both main cable and stiffened beam share force distribution, with main cable serving as the primary load-bearing component that deforms under stress.
Main Cable Types
- Wire Rope Main Cable: 7-strand construction for smaller span applications
- Parallel Wire Bundle Main Cable: Prefabricated parallel steel wire strand (PPWS) method for accelerated construction
Bridge Tower Configurations
Mechanical Properties
- Rigid Tower: Minimal horizontal displacement at top
- Flexible Tower: Significant horizontal displacement capability
- Rocking Column Tower: Hinged single-column for smaller spans
Cross Bridge Forms
- Truss type structure
- Rigid frame type design
- Mixed type configurations
Stiffening Beam Variants
- Steel truss beams
- Steel box beams
- Concrete beams
- Steel-mixed composite beams
Anchorage Systems
- Gravity Anchorage: Composed of anchor body, bollard, anchor chamber and foundation
- Tunnel Anchorage: Composed of anchor plug body, loose saddle support pier and anchor chamber
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 anchorage
- Self-Anchoring: Main cable tension transmitted directly to stiffening beam
Key Advantages
- Superior span capacity for structures over 1000 meters
- Excellent seismic performance and structural resilience
- Lightweight appearance with inherent flexibility
- Accelerated construction timeline compared to alternative bridge types
Protection Systems
Concrete Structure Protection
- Enhanced concrete protective layer thickness
- High-performance durable concrete formulations
- Protective coatings and sealing layers
- Advanced reinforcement materials and corrosion inhibitors
Steel Structure Protection
- Paint coating systems
- Thermal spray zinc/aluminum alloy coatings
- Weathering steel applications
- Environmental improvement measures
