The steel box-girder bridge is a composite structure designed for easy repair and maintenance. It typically consists of top plate (bridge panel), beam web, bottom plate, longitudinal stiffener, transverse stiffener, and diaphragm plate (cross beam).
Orthotropic Steel Bridge Panels
The basic forms of longitudinal rib section are open and closed. The cross-section form of the ribs is usually inverted T shape, with spacing equal to the span of the longitudinal ribs. Transverse ribs feature notches to allow continuous passage of longitudinal ribs.
Structural Forms of Steel Box-Girder Bridge
Single Box Steel Beam Bridge
Features steel deck to improve bridge panel stiffness with spacing of 1.5m-3m (open rib). Ideal for bridges with small width (3 lanes) or width-to-span ratio ![Single box steel beam bridge structure showing web and stiffeners]()

Single Box Multi-Chamber
Rarely used as middle belly plate has minimal influence on the torsional rigidity of the steel box girder.
Double Box Steel Girder Bridge
Used when bridge width is large or single box size makes production, transportation, or installation difficult. Beam setting can be optional depending on design requirements.
Multi-box Steel Girder Bridge
Ideal for small spans with large bridge widths. Main beams are arranged uniformly to ensure even force distribution.
Longitudinal Beam Structure
Reduces span of reinforced concrete bridge panels (not exceeding 3m) and improves steel bridge panel stiffness. For wide bridges, longitudinal beams can be set when transverse rib spacing is small.
Support and Temporary Fulcrum Arrangement
Single-box bridges require two supports at each end for structural stability and torque resistance. Multi-box bridges typically use one support per steel box. Temporary fulcrums with jacks are provided for structural reinforcement during installation.
Mechanical Characteristics and Structural Measures
Steel box-girder bridges may experience bending failure, distortion under torque, or web crumpling under concentrated force. Structural measures include:
- Adequate transverse partitions to prevent distortion
- Sufficient stiffening ribs to prevent compression flange instability
- Stiffening ribs to prevent tension flange stress during handling
- Transverse and longitudinal ribs to prevent web buckling
Structural Characteristics
Applications
Suitable for road, rail, and high-speed rail infrastructure projects.
Advantages
- Light weight with steel savings compared to truss girder bridges
- High flexural and torsional stiffness
- Quick installation and easy maintenance
- Suitable for forming continuous beams
- Simple, aesthetically pleasing design
- Large flange width for superior bending resistance and long spans
- Excellent for curved bridges with uniform lateral load distribution
- Hollow structure allows easy access for ancillary facilities and maintenance
