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.
