Product Description
Composite Steel Bridge Overview
Rigid frame composite steel bridges combine steel structural members with reinforced concrete components using shear connectors to create efficient, cost-effective bridge solutions for various applications.
Structural Design & Composition
Composite beam bridges feature a segmented design where steel beam ribs (plate beams, box beams, or truss beams) work in conjunction with reinforced concrete bridge panels. This staged stress distribution optimizes material performance and reduces construction costs.
Key Structural Types
  • Composite Plate Girder Bridge: Utilizes I-section steel beams for medium spans, available as rolled sections or welded constructions
  • Composite Box Girder Bridge: Offers superior torsional rigidity, ideal for curved bridges and continuous structures
  • Composite Rigid Frame Bridge: Integrates steel-concrete beams with concrete piers, providing enhanced seismic performance and eliminating support requirements
  • Composite Truss Bridge: Employs steel truss systems combined with concrete panels for improved aesthetics and permeability
  • Technical Advantages
  • Increased section stiffness with reduced steel quantity
  • Lower noise levels compared to all-steel bridges under live loads
  • Flexible slope and superelevation adjustment capabilities
  • Reduced dead load compared to concrete bridges
  • Optimized material utilization: steel handles tension, concrete handles compression
  • Construction convenience with lightweight, easily assembled components
