Structural Overview

The cable-stayed bridge, also known as a diagonal bridge, features a structural system where the main beam is directly supported by multiple cables attached to bridge towers. This system consists of three primary components: the pressurized tower, strained cables, and bent beam body.

Primary Components

Main Beam: Typically constructed from concrete, steel-concrete composite, or pure steel structure
Cable Tower: Primarily concrete structures, with some steel-concrete combinations or pure steel variants
Stay Cable: Manufactured from high-strength materials like steel wire or steel strand

The cable-supported design significantly reduces beam bending moments, allowing for smaller beam dimensions (typically 1/50 to 1/200 of the span) while increasing the bridge's crossing capacity.

Span Configurations

Twin Tower Three Span: Ideal for crossing large rivers with its substantial main span
Single Tower Double Span: Suitable for small-to-medium rivers and urban channels
Multi-Tower Designs: Require careful engineering to control tower displacement and beam bending moments

The key to multi-tower cable-stayed bridge design lies in controlling horizontal displacement of middle tower tops under live load and reducing mid-span bending moments in the main beam.

Cable Tower Design

Cable towers serve as both structural supports and aesthetic elements. Their design must accommodate cable arrangements while maintaining axial compression under dead load. Common configurations include single-column, A-shape, and inverted Y-type towers.

Stay Cable Arrangements

Modern cable-stayed bridges typically use dense cable systems with spacing of 4-20m, offering advantages in beam moment reduction, anchoring simplicity, and construction safety.

Structural Advantages

Compact beam dimensions with exceptional crossing capacity
Minimal clearance and elevation restrictions
No need for complex anchorage structures
Adaptability to cantilever construction methods
