The composite beam bridge is a composite structural bridge that 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.
- Combined section design increases stiffness while reducing steel quantity
- Reduced noise compared to all-steel bridges under live load
- Easy adjustment of slope and external superelevation
- Uses short section steel components (channel steel, angle steel)
- Flexible shear transfer system with welded connections
I-section steel beams for medium and small spans, reducing production and installation costs. Can use rolled section steel or welded steel beams with asymmetric sections to optimize material usage.
Higher torsional rigidity and stability than I-section bridges. Solves clearance issues and avoids traffic interruption during construction. Can incorporate concrete in negative bending moment zones for improved stability.
Steel-concrete composite beams consolidated with concrete piers, reducing bridge floor load and support requirements. Features specialized beam-pier joint structures for effective load transfer.
- Convenient construction due to steel strength and light weight
- Reduced dead load compared to concrete bridges
- Optimized material performance (steel in tension, concrete in compression)
- Cost efficiency in materials, construction, and maintenance
- Rapid construction process
- Durable and resilient design
- Flexible design options for various applications
- Highway bridges
- Railway bridges
- Pedestrian bridges
