Structural Overview
Our steel cable suspension bridge is engineered for superior seismic performance and can span long distances without intermediate supports, making it ideal for crossing wide rivers, deep valleys, or expansive bodies of water. The structure consists of:
- Bridge tower
- Main cable
- Sling
- Stiffening beam
- Anchor
- Saddle
Load Characteristics
The load is efficiently transmitted from the sling to the cable, then to the anchor, pier, and tower. Both the main cable and stiffened beam share the load-bearing responsibility:
Main Cable: Primary load-bearing component that deforms under load, affecting the bridge's internal force and deformation.
Bridge Tower: Resists vertical loads and supports the entire structure.
Sling: Transmits weight and external loads from the stiffened beam to the main cable.
Anchor: Secures the main cable and transfers tension to the foundation.
Stiffening Beam: Provides structural stiffness and ensures vehicle stability, primarily bearing bending internal forces.
Main Cable Types
Our suspension bridges feature two main cable configurations:
- Wire Rope Main Cable: 7-strand twisted construction, ideal for smaller span bridges
- Parallel Wire Bundle Main Cable: Prefabricated parallel steel wire strand (PPWS) method for faster construction, available in pointed or flat top shapes
Bridge Tower Design
Our bridge towers are engineered for optimal performance:
- Structural Forms: Rigid tower (small horizontal displacement), Flexible tower (larger displacement), Rocking column tower (small span bridges)
- Cross Bridge Forms: Truss type, Rigid frame type, Mixed type structure
Stiffening Beam Options
Multiple stiffened beam configurations available:
- Steel truss beams
- Steel box beams
- Concrete beams
- Steel-mixed composite beams
Sling Specifications
Our slings are designed for maximum durability and performance:
- Materials: Steel wire rope, parallel steel wire bundle, or steel strand
- Connection Modes: Straddle type, pin type
- Types: Vertical sling (traditional), Diagonal sling (modern)
Anchorage Systems
We offer two superior anchorage solutions:
- 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 (more economical)
Classification Options
Our suspension bridges are available in multiple configurations:
By Suspension Span: Single-span, three-span, four-span, five-span
By Main Cable Anchoring: Ground anchor (tension transferred to foundation) or self-anchoring (tension transmitted to stiffening beam)
Construction Process
Our systematic construction approach ensures quality and efficiency:
- Anchor foundation and bridge tower foundation construction
- Bridge tower and anchor body construction
- Main cable system installation
- Stiffened beam segments hoisting and erection
- Bridge deck and ancillary works completion
Protection Systems
We implement comprehensive protection measures for long-term durability:
Concrete Structure Protection:
- Increased concrete protective layer thickness
- High performance durable concrete
- Protective coatings and sealants
- Corrosion-resistant reinforcement
Steel Structure Protection:
- Advanced paint coating systems
- Thermal spray zinc/aluminum alloys with fluorocarbon topcoat
- Weathering steel options
- Environmental controls
Key Advantages
- Superior span capacity (1000m+) without intermediate supports
- Excellent seismic performance
- Lightweight yet strong structural design
- Efficient tension-based load distribution
- Faster construction through prefabricated components
- Minimal environmental impact during installation
