A composite beam bridge combines steel members (such as steel plate beams, steel box beams, or steel truss beams) with reinforced concrete members through shear connectors to create a unified structural system. The steel section provides high tensile strength and stiffness, while the concrete slab offers excellent compressive strength and protects the steel from fire and corrosion.
Types of Composite Beam Bridges
Concrete Composite Beams: Integrated by casting concrete in situ in the joints or together with the precast slab of the bridge floor.
Steel-Concrete Composite Beams: Made of steel beams in the beam ribs and reinforced concrete slabs in the bridge panels, combined through shear keys (connectors).
Structural Characteristics
- Reduced noise compared to all-steel bridges
- Easy slope and superelevation adjustment
- Combined section increases stiffness while reducing steel quantity
- Requires reliable shear transfer devices between steel and concrete
Structural Forms
Composite Plate Girder Bridge: Uses I-section steel beams for medium and small spans, reducing production and installation costs.
Composite Box Girder Bridge: Offers higher torsional rigidity and stability than I-section bridges, with construction methods including cast-in-place and precast segmental.
Composite Truss Bridge: Uses steel truss instead of solid steel beam for better permeability and aesthetics, though with more complex joint designs.
Composite Rigid Frame Bridge: Consolidated with concrete piers for improved seismic performance and larger headroom under the bridge.
Key Advantages
- Convenient construction due to steel's strength and light weight
- Reduced dead load compared to concrete bridges
- Optimal material performance with steel in tension and concrete in compression
- Cost savings, especially in long-span bridges
- Reduced steel quantity and painting costs
- Improved stiffness, stability, and structural integrity
Bridge Panel Design
Reinforced concrete bridge panels bear longitudinal bending moments and cross-bridge internal forces. They can be cast-in-place or precast, with straight or curved bottom surfaces.
Shear Connectors
Critical for joint operation of steel and concrete, shear connectors withstand longitudinal shear forces and resist relative slip. Common types include welded nail shear keys, channel steel shear keys, and perforated plate connectors.
