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

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
