Product Description
Cable-Stayed Bridge Engineering Overview
Cable-stayed bridges, also known as diagonal bridges, feature main beams directly supported by cables anchored to bridge towers. This structural system consists of compressed towers, tensioned cables, and flexural beam elements.
Structural Components
Main Beam Systems
The main beam functions as a continuous beam with multiple elastic supports, significantly reducing bending moments and structural dimensions. Beam heights typically range from 1/50 to 1/200 of the span length.
Cable Tower Configurations
Available in single-column, double-column, portal/H-type, A-type, and diamond/inverted Y-type designs to accommodate various structural requirements.
Stay Cable Construction
Manufactured from high-strength steel wire or steel strand, stay cables are available in parallel wire cables with cold-cast anchors or parallel steel cables with clip anchors.
Span Layout Configurations
Twin Tower Three-Span Design
Ideal for crossing large rivers with main spans typically exceeding 200 meters.
Single Tower Double-Span Design
Suitable for small to medium rivers and urban channels with spans generally under 200 meters.
Multi-Tower Systems
Three-tower four-span and multi-tower configurations require careful design to control horizontal displacement and reduce mid-span bending moments.
Material Specifications & Span Capabilities
Our cable-stayed bridges support various material configurations with optimized span capabilities:
- Prestressed Concrete Beams: Economic spans up to 400 meters
- Steel-Concrete Composite Beams: Economic spans 400-600 meters
- All-Steel Main Beams: Economic spans exceeding 600 meters
- Hybrid Systems: Steel main spans with concrete side spans for 600+ meter applications
