Product Description
Steel Box Girder Bridge Overview
High stiffness steel box girder bridges are engineered for rapid installation using prefabricated materials. These structures consist of top plate (bridge panel), beam web, bottom plate, longitudinal stiffeners, transverse stiffeners, and diaphragm plates (cross beams).
Structural Components
Orthotropic Steel Bridge Panels
The top plate features welded vertical and horizontal stiffeners forming an orthogonal bridge panel system. This design provides excellent mechanical properties in both bridge directions while optimizing steel usage for local wheel load bearing.
Longitudinal Rib Configurations
Available in open and closed cross-section forms, typically featuring inverted T-shape profiles with continuous passage through transverse rib notches.
Bridge Configuration Types
Single Box Steel Girder Bridge
Ideal for bridges up to 3 lanes or width-to-span ratios below 1/10. For 4-6 lane applications, double-width single box girder configurations are recommended.
Double Box Steel Girder Bridge
Suitable for wider bridges where single box dimensions become impractical for production, transportation, or installation.
Multi-Box Steel Girder Bridge
Optimal for smaller spans with substantial bridge widths, featuring uniformly spaced main beams for balanced load distribution.
Technical Specifications & Performance
Structural Support Systems
Each single-box steel beam bridge requires two end supports for structural stability and torque resistance. Multi-box configurations feature one support per steel box with temporary fulcrum arrangements for jack support during construction.
Mechanical Characteristics
Engineered to withstand bending moments, torque distortion, and concentrated forces through strategic placement of transverse partitions, stiffening ribs, and reinforcement systems.
