Steel Cable Suspension Pedestrian Bridge - 1000m+ Span Capacity with AASHTO HL93 Loading Standards for Industrial Applications

A flexible suspension combination system composed of main cable and stiffened beam, combining stress characteristics of both cable and beam structures. Ideal for spans exceeding 1000m with superior seismic performance and lightweight appearance.

Primary load-bearing component transmitting forces from slings to anchors, piers, and towers. Available in two configurations:

• Wire Rope Main Cable: 7-strand construction for smaller span applications
• Parallel Wire Bundle Main Cable: PPWS method with pointed or flat-top cross-sections

Critical load-bearing component resisting vertical loads with three structural forms:

• Rigid Tower: Minimal horizontal displacement at top
• Flexible Tower: Significant horizontal displacement capability
• Rocking Column Tower: Hinged single-column for smaller spans

Secondary structure ensuring vehicle operation and providing structural stiffness:

• Steel truss beams
• Steel box beams
• Concrete beams
• Steel-mixed composite beams

By Span Configuration: Single-span, three-span, four-span, five-span designs

By Anchoring Method:

• Ground Anchorage: Gravity or tunnel anchorage transferring tension to foundation
• Self-Anchoring: Direct tension transmission to stiffening beam

Concrete Structure Protection:

• Enhanced concrete protective layer thickness
• High-performance durable concrete
• Protective coatings and sealing layers
• Reinforcement corrosion inhibitors
• Cathodic protection systems

Steel Structure Protection:

• Advanced paint coating systems
• Thermal-sprayed zinc/aluminum alloys with fluorocarbon topcoats
• Weathering steel applications
• Environmental improvement measures
