Rigid Frame Steel Cable Suspension Bridge Professional For River Crossings
| Product Name: Steel Cable Suspension Bridge | Material: Steel |
| Spans: Large Spans | Type: Suspension Bridges |
| Usage: Heavy Loading, Railway Traffic | Decking Material: Steel Concrete |
The Steel Cable Suspension Bridge is a flexible suspension combination system composed of a main cable and stiffened beam, combining the stress characteristics of both cable and beam structures. This professional bridge solution consists of several key components:
- Bridge tower
- Main cable
- Sling
- Stiffening beam
- Anchor
- Saddle
The load is transmitted from the sling to the cable, then to the anchor, pier, and tower. Both the main cable and stiffened beam bear force under external loads. The main cable serves as the primary load-bearing component, with its deformation directly affecting the bridge's internal force and deformation characteristics.
The primary load-bearing element, available in two types:
- Wire rope main cable: Used for small span suspension bridges
- Parallel wire bundle main cable: Prefabricated parallel steel wire strand method (PPWS) for faster construction
Structural forms include:
- Rigid tower: Small horizontal displacement at top
- Flexible tower: Large horizontal displacement at top
- Rocking column tower: For small span suspension bridges
Available in multiple structural forms:
- Steel truss beams
- Steel box beams
- Concrete beams
- Steel-mixed composite beams
Suspension bridge construction involves five primary steps:
- Foundation construction of bridge tower and anchor
- Construction of bridge tower and anchor body
- Installation of cable system
- Hoisting of stiffened beam segments
- Bridge deck and ancillary works
- By suspension span: Single-span, three-span, four-span, five-span
- By main cable anchoring: Ground anchor and self-anchoring
- Highway bridges spanning large bodies of water or deep valleys
- Pedestrian and cyclist crossings in scenic locations
- River crossings in urban and rural settings
- Increased concrete protective layer thickness
- High performance concrete with enhanced durability
- Protective coatings and sealing layers
- Paint coating systems
- Thermal spray protection with zinc/aluminum alloys
- Use of weathering steel
- Superior span capacity (over 1000m)
- Excellent seismic performance
- Lightweight appearance
- Cost-effective for large span applications
