Structural Overview

The steel box-girder bridge features exceptional flexural and torsional stiffness with significant loading capacity. Composed of top plate (bridge panel), beam web, bottom plate, longitudinal stiffener, transverse stiffener, and diaphragm plate (cross beam), it offers superior structural integrity.

Key Construction Features

Factory welding is prioritized to ensure weld quality, with strict quality control measures. The top plate's lower edge incorporates vertical and horizontal stiffeners forming an orthogonal bridge panel, optimizing mechanical properties in both bridge directions while conserving steel.

Structural Variations

Single Box Design: Ideal for smaller bridge widths (3 lanes) with beam spacing of 1.5m-3m (open rib) or 2m-4m (closed rib).

Double Box Design: Recommended for wider bridges where single box dimensions become impractical for production, transportation, or installation.

Multi-box Design: Optimal for applications with small spans and large bridge widths, featuring uniformly-spaced main beams for balanced load distribution.

Structural Components

Longitudinal Beam

Reduces span of reinforced concrete bridge panels when main beam spacing is large, while improving steel bridge panel stiffness. Spacing typically limited to 3m for concrete panels.

Support Systems

Multi-box designs utilize one support per steel box. Temporary fulcrum supports with jacks are implemented for structural reinforcement during installation.

Mechanical Characteristics

Engineered to withstand bending moments and concentrated forces, with structural measures including:

Transverse partitions to prevent distortion and lateral bending
Stiffening ribs to maintain compression flange stability
Reinforcement for tension flange during fabrication and installation
Web stiffening to prevent buckling under stress

Applications & Advantages

Applications: Road, rail, and high-speed rail infrastructure projects requiring durable, long-span solutions.

Key Benefits

Large flange width provides exceptional bending resistance
Superior torsional stiffness for curved bridge applications
Lightweight construction with significant steel savings
High flexural and torsional stiffness
Rapid installation with simplified maintenance
Continuous beam formation capability
Modern, aesthetically pleasing design
