Structural Composition

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). Plate thickness typically ranges from 12-30mm for main components and 10-20mm for secondary plates.

Orthotropic Steel Bridge Panels

Longitudinal rib sections feature both open and closed forms, typically in inverted T shape configuration. Transverse ribs include notches to allow continuous passage of longitudinal ribs.

Bridge Types

Single Box Steel Girder Bridge

Ideal for bridges with width ≤3 lanes or width-to-span ratio <1/10. Features effective flange width with main beam web interval ≤Le/5 and cantilever length ≤Le/10.

Double Box Steel Girder Bridge

Used when bridge width makes single box impractical due to size, production, or transportation constraints.

Multi-box Steel Girder Bridge

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

Key Structural Components

Longitudinal Beam

Reduces span of concrete bridge panels (≤3m spacing) and enhances steel panel stiffness.

Transverse Beam

Spacing ≤6m with longitudinal beams or ≤20m without, serving critical lateral load distribution functions.

Support Systems

Single-box bridges require two end supports for stability, while multi-box designs use one support per box with temporary jack supports during construction.

Structural Characteristics

Steel box bridges feature sleek, streamlined designs with geometric flexibility for straight or curved spans. Integrated bridge decks create cohesive appearances with customizable railings and parapets.

Performance Advantages

Superior flexural and torsional stiffness

Lightweight construction with steel efficiency

Rapid installation and minimal maintenance

Excellent weather and corrosion resistance

Adaptable for continuous beam configurations

Aesthetic, streamlined appearance

Hollow structure facilitates utility integration
