The cable-stayed bridge, also known as diagonal bridge, is a structural system composed of a pressurized tower, strained cables, and a bent beam body where the main beam is directly pulled on the bridge tower with multiple cables.
- Exceptional crossing ability with reduced beam height
- Horizontal cable components balanced by axial pressure of main beam
- Composed of three primary components: main beam, cable tower, and stay cable
Main Beam: Typically constructed from concrete, steel-concrete combination, or steel structure
Cable Tower: Primarily concrete structures, with some steel-concrete combinations
Stay Cable: Manufactured from high-strength materials (steel wire or steel strand)
The cable-stayed bridge efficiently transfers dead load and vehicle load from the main beam to the cable tower through anchored stay cables, then to the foundation. This multi-span elastic support system significantly reduces bending moment and structural weight while increasing crossing capacity.
- Twin Tower Three Span: Ideal for crossing large rivers with substantial main spans
- Single Tower Double Span: Suitable for small/medium rivers and urban channels
- Multi-Tower Spans: Requires careful consideration of structural flexibility
Cable towers serve as both structural supports and aesthetic elements, with various configurations including single column, A-shape, inverted Y type, and more. Tower height significantly impacts overall bridge stiffness and economy.
Modern cable-stayed bridges primarily use dense cable systems with advantages including reduced main beam bending moment, simplified anchoring, and easier construction/maintenance.
- Compact beam dimensions with exceptional crossing capacity
- Minimal clearance and elevation restrictions
- Simplified construction compared to suspension bridges
- Adaptable to various span requirements
