Product Description
Structural Design & Components
Steel arch bridges feature a robust structural system primarily composed of arch ring, suspension rods (or arch columns), tie rods, and bridge beams. For optimal structural integrity, diagonal braces or scissors braces are strategically positioned between arch seat columns and near arch foot connections.
Arch Bridge Classification Systems
By Structural Form:
- Main arch ring section: Steel box arch, steel pipe arch, steel truss arch
- Arch rib spatial positioning: Parallel arch ribs, basket arch ribs, butterfly arch ribs
- Carriageway position: Upper bearing, middle bearing, and lower bearing types
- Boom layout: Parallel vertical boom, inclined boom, mesh boom
By Structural System:
- Simple system arch bridge: Arch ring as primary load-bearing component with thrust directly transferred to piers/foundations
- Combined system arch bridge: Carriageway beam and arch combination sharing load distribution
Key Structural Components
Arch Rib
Primary load-bearing member designed as box, pipe, or truss type sections. Truss arch ribs offer superior weight efficiency and span capacity.
Boom System
Force transfer components transmitting deck loads to arch ribs. Available as rigid booms (steel pipe/section steel) or flexible booms (high-strength steel wire bundles).
Tie Rods
Critical for non-thrust arches, bearing substantial axial tension loads. Options include rigid and flexible tie rod configurations.
Cross Braces
Essential for transverse stiffness and stability, resisting horizontal forces. Common types: one-word, K-shaped, X-shaped, and meter-shaped braces.
Technical Specifications & Design Parameters
Span Capabilities: 10M to 300M single span
Rise Span Ratio: Typically 1/4 to 1/5 for steel truss arch bridges
Arch Axis Forms: Arc line, quadratic parabola, catenary configurations
