Main Structural Form of Steel Arch Bridge
Steel arch bridges employ an arch structure made primarily of steel, designed to bear weight and forces from traffic while distributing them evenly to supports at each end. Steel's high recyclability makes these bridges environmentally friendly and sustainable.
Structural Classification
- Section form: Steel box arch, steel pipe arch, steel truss arch
- Space posture: Parallel arch ribs, basket arch ribs, butterfly arch ribs
- Carriageway position: Upper bearing type, middle bearing type, lower bearing type
- Boom layout: Parallel vertical boom, inclined boom, mesh boom
Structural System Classification
Steel arch bridges include both composite system and simple system designs. Composite systems combine the arch with other structural elements, while simple systems rely solely on the arch ring as the main force component.
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
- Boundary conditions
- Bar section form and area
Steel arch bridges are renowned for their exceptional strength, durability, and aesthetic appeal. The arch shape provides excellent load-bearing capabilities by efficiently transferring weight to supports.
Key Structural Components
Arch Rib
The primary load-bearing member that mainly withstands axial pressure. Available in box, pipe, and truss types, with trussed arches offering light weight, greater span capacity, and good economy.
Boom
Transfers deck load to the arch rib. Available as rigid (steel pipe/section) or flexible (high-strength steel wire) configurations, with various elevation arrangements including parallel vertical, inclined, and mesh booms.
Tie Bar (Beam)
Bears the thrust of non-thrust arches, available in rigid and flexible configurations to withstand significant axial tension.
Cross Brace
Ensures transverse stiffness and stability, with common configurations including one-word, K-shaped, X-shaped, and meter-shaped braces positioned according to structural requirements.
Design Parameters
Key considerations include rise span ratio (typically 1/4~1/5), arch axis form (arc line, quadratic parabola, catenary), and vault/arch foot height selection (equal or variable height).
Advantages of Steel Arch Bridges
- Strength & Durability: High-strength material withstands heavy loads and harsh conditions
- Constructability: Suitable for prefabrication and modular construction methods
- Recyclability: Environmentally friendly with high material recyclability
- Aesthetic Appeal: Attractive architectural form with clean lines
Applications
- Road bridges requiring long spans
- Pedestrian bridges in urban areas
- Highway overpasses crossing other infrastructure
- Railway bridges requiring durable structures
