Product Description

Permanent Steel Cable Suspension Bridge Overview

Steel cable suspension bridges represent a flexible suspension combination system composed of main cables and stiffened beams, combining the stress characteristics of both cable and beam structures. These bridges are the preferred solution for spans exceeding 1000 meters due to their exceptional load-bearing capacity, seismic performance, and lightweight appearance.

Structural Components

The suspension bridge system consists of several critical components working in harmony:

Main Cable System

The primary load-bearing component that transmits forces from the deck to the anchorages. Available in two configurations:

Wire Rope Main Cable: 7-strand twisted construction for smaller span applications
Parallel Wire Bundle Main Cable: Prefabricated parallel steel wire strand (PPWS) method for accelerated construction

Bridge Tower

Vertical support structures that resist the cable forces. Available in multiple configurations:

Mechanical Types: Rigid tower, flexible tower, and rocking column tower
Cross Bridge Forms: Truss type, rigid frame type, and mixed type structures
Stiffening Beam

Secondary structure ensuring vehicle stability and providing structural stiffness. Options include:
- Steel truss beams
- Steel box beams
- Concrete beams
- Steel-concrete composite beams
  Anchorage Systems
  
  Structures that anchor the main cable tension to the foundation:
  - Gravity Anchorage: Suitable for nearly all construction conditions
  - Tunnel Anchorage: Economical alternative with significantly reduced concrete consumption
    Technical Classification
    
    By Suspension Span Configuration
    - Single-span suspension bridge
    - Three-span suspension bridge
    - Four-span suspension bridge
    - Five-span suspension bridge
      By Main Cable Anchoring Method
      - Ground Anchorage: Main cable tension transferred to foundation via gravity or tunnel anchors
      - Self-Anchoring: Main cable tension transmitted directly to stiffening beam
        Construction Methodology
        
        The systematic construction process includes anchor foundation construction, anchor installation, bridge tower foundation and construction, main cable installation, stiffened beam assembly, and bridge deck construction.
