Structural Composition

The steel box-girder bridge consists of:

Top plate (bridge panel)
Beam web
Bottom plate
Longitudinal stiffener
Transverse stiffener
Diaphragm plate (cross beam)

Standard plate thickness ranges from 12-30mm for main components and 10-20mm for secondary plates. Manufactured in factory fragments (10-30m sections) with site welding for final assembly.

Orthotropic Steel Bridge Panels

Featuring longitudinal rib sections in open and closed configurations with inverted T-shape cross-sections for optimal structural performance.

Bridge Types and Applications

Box girder construction serves as the primary beam form for various bridge types including beam bridges, suspension bridges, and cable-stayed bridges.

Single Box Steel Beam Bridge

Ideal for bridges with smaller widths (≤3 lanes) or width-to-span ratios <1/10. Features include:

Effective flange width: main beam web interval ≤Le/5
Main beam cantilever length ≤Le/10
Steel deck improves bridge panel stiffness

Double Box Steel Girder Bridge

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

Multi-box Steel Girder Bridge

Optimal solution for applications with small spans and large bridge widths, featuring uniformly spaced main beams for balanced load distribution.

Structural Support Systems

Engineered support configurations ensure structural stability:

Single-box bridges require two end supports for torque resistance
Multi-box bridges utilize one support per steel box
Temporary fulcrum supports strengthen during construction

Mechanical Characteristics

Engineered to withstand various stress conditions:

Compression flange stability under bending moment
Torsional resistance through transverse partitions
Web reinforcement to prevent buckling

Key Advantages

Lightweight construction with steel savings up to 20%
Superior flexural and torsional stiffness
Rapid installation with minimal maintenance requirements
Excellent suitability for continuous beam formation
Aesthetic, streamlined appearance
Hollow structure facilitates maintenance access

Applications

Versatile solutions for:

Road bridges
Railway crossings
High-speed rail infrastructure
