Steel Box-Girder Bridge Structure

The steel box-girder bridge is composed of top plate (bridge panel), beam web, bottom plate, longitudinal stiffener, transverse stiffener, and diaphragm plate (cross beam). Factory welding is preferred to ensure weld quality, with strict quality control measures.

Orthotropic Steel Bridge Panels

The top plate features vertical and horizontal stiffeners forming an orthogonal bridge panel. This design offers excellent mechanical properties in both bridge directions, efficiently bears local wheel loads, and optimizes steel usage.

Box girders serve as primary beam forms for various bridge types including beam bridges, suspension bridges, and cable-stayed bridges.

Bridge Types and Applications

Single Box Steel Beam Bridge

Ideal for bridges with width ≤3 lanes or width-to-span ratio <1/10. Features include:

Effective flange width: main beam web interval ≤Le/5
Main beam cantilever length ≤Le/10
Beam spacing: 1.5m-3m (open rib) or 2m-4m (closed rib)

Double Box Steel Girder Bridge

Used when bridge width is large or single box dimensions become impractical for production, transportation, or installation.

Multi-box Steel Girder Bridge

Optimal for wide bridges with small spans, featuring uniformly spaced main beams for balanced load distribution.

Structural Components

Longitudinal Beam

Reduces span of reinforced concrete bridge panels and enhances steel bridge panel stiffness. Spacing ≤3m for concrete panels.

Transverse Beam

Spacing ≤6m when longitudinal beams are present (max 20m without). Ensures lateral load distribution and supports longitudinal beams/bridge panels.

Support Systems

Single-box bridges require two end supports for stability. Multi-box bridges typically use one support per box, with temporary fulcrums for structural reinforcement during installation.

Mechanical Characteristics

Steel box-girder bridges are designed to withstand:

Bending moment-induced compression flange instability
Torque-induced distortion
Concentrated force-induced web crumpling

Structural Reinforcement Measures

Critical reinforcement includes transverse partitions to prevent distortion, stiffening ribs to maintain flange stability, and web reinforcement to resist buckling during fabrication and installation.

Advantages

Superior structural efficiency and stiffness
Versatile applications for road, rail, and high-speed rail
Rapid installation and simplified maintenance
Enhanced durability and longevity
Sustainable construction solution
Lightweight design with optimized steel usage
Excellent torsional resistance and aesthetic appeal
