Concrete Decking Temporary Steel Bridge Truss Steel Bridge Weather Resistance
The composite beam bridge combines steel members (plate beams, box beams, truss beams) with reinforced concrete components through shear connectors, creating an efficient structural system that leverages the strengths of both materials.
| Attribute | Specification |

| Product Name | Composite Beam Bridge |
| Bridge Deck | Concrete |
| Material | Prefabricated Steel |
| Spans | Small, Medium, Large Spans |
| Durability | Long-lasting construction |
| Installation | Efficient modular process |
- Combined section design increases stiffness while reducing steel quantity
- Reduced noise compared to all-steel bridges under live loads
- Easy adjustment of slope and superelevation
- Requires reliable shear transfer devices between steel and concrete components
I-section steel beams for medium/small spans, using rolled or welded steel sections. Asymmetric steel beam sections reduce upper flange size attached to concrete panels.
Superior torsional rigidity and stability compared to I-section designs. Features longitudinal stiffeners for enhanced load distribution and reduced deflection.
Steel truss replaces solid beams, offering better permeability and aesthetic appeal while maintaining structural integrity.
Integrated with concrete piers for seismic resistance, large headroom, and improved bridge floor smoothness.
Critical component ensuring steel-concrete composite action through welded nail shear keys, channel steel shear keys, or perforated plate connectors.
- Lightweight construction with easy installation
- Reduced dead load compared to concrete bridges
- Optimized material performance (steel in tension, concrete in compression)
- Cost-effective solution for long-span applications
- Highway and railway bridges
- Pedestrian bridges with aesthetic designs
- Long-span structures requiring lightweight solutions
