Structural Overview
The steel arch bridge utilizes an arch-shaped structure made of steel to span gaps or obstacles. The bridge floor structure is suspended on the arch rib, with the horizontal thrust borne by the tie rod, creating an "arch-tie rod" combination structure known as a tie rod arch.
Structural Classification
- By section form: Steel box arch, steel pipe arch, steel truss arch
- By space posture: Parallel arch ribs, basket arch ribs, butterfly arch ribs
- By carriageway position: Upper bearing type, middle bearing type, lower bearing type
- By boom layout: Parallel vertical boom, inclined boom, mesh boom
Structural Systems
Simple system arch bridge: Only the arch ring bears force, with thrust directly borne by piers or foundation.
Combined system arch bridge: Carriageway beam and arch work together, sharing the load.
Main Arch Structure
Steel arches can be designed as truss arches, box arches, or plate arches. Truss arch bridges are particularly important for large spans, with design considerations including:
- Arch rib truss layout
- Arch axis configuration
- Vector span ratio
- Vault and arch foot height selection
- Bar section form and area
Key Components
Arch rib: Main load-bearing member, primarily under axial pressure. Available in box, pipe, or truss forms.
Boom: Transfers deck load to arch ribs. Can be rigid (steel pipe/section) or flexible (steel wire bundle).
Tie bar: Bears arch thrust in non-thrust arches. Can be rigid or flexible.
Cross brace: Provides transverse stiffness and stability. Common forms include one-word, K-shaped, X-shaped, and meter-shaped braces.
Design Parameters
- Rise span ratio: Typically 1/4~1/5 for steel truss arches
- Arch axis: Common forms include arc line, quadratic parabola, catenary
- Arch rib height: Equal height or variable height designs
Key Features
- Arch-shaped design for optimal load distribution
- Steel construction for strength and durability
- Requires abutments and piers for support
- Excellent span capabilities
- Aesthetic appeal
Applications
- Pedestrian bridges
- Railway bridges (especially long spans)
- Road bridges
- Highway crossings
