Structural Form of Steel Arch Bridge
The upper structure of steel arch bridge is mainly composed of arch ring, suspension rod (or arch column), tie rod, bridge beam and other components.
Classification by Structure
- Section form of main arch ring: Steel box arch, steel pipe arch, steel truss arch
- Space posture of two arch ribs: Parallel arch ribs, basket arch ribs, butterfly arch ribs
- Position of carriageway system: Upper bearing type, middle bearing type and lower bearing type arch bridge
- Layout of boom: Parallel vertical boom, inclined boom, mesh boom
Structural System Classification
Steel arch bridges include both composite system arch bridges and simple system arch bridges. Composite systems include tie arch, loser arch, lange arch and other combined system arch bridges.
Main Arch Structure
Steel arch can be designed into truss arch, box arch, or plate arch. Truss arch bridges are common internationally, while China has built numerous steel box arch bridges. Truss arch bridges are particularly important for large span applications.
Key Design Parameters
- Layout of arch rib truss
- Arch axis configuration
- Vector span ratio
- Height selection for vault and arch foot
- Boundary conditions
- Bar section form and area
Trussed arch ribs can be classified as Pratt truss, Warren truss, K truss, or sub-truss forms. K-type trusses offer superior mechanical properties, W-type trusses are most economical, and P-type trusses provide construction and aesthetic advantages.
Key Components of Steel Arch Bridges
1. Arch Rib
The primary load-bearing member that mainly withstands axial pressure while also resisting bending moments. Available in box, pipe, or truss configurations, with trussed arches offering superior weight efficiency and span capacity.
2. Boom
Force transfer components that transmit deck loads to arch ribs. Available as rigid (steel pipe/section steel) or flexible (high-strength steel wire) configurations with various elevation arrangements including parallel vertical, inclined, or mesh patterns.
3. Tie Rod (Beam)
Critical for non-thrust arches, these components bear the arch's axial tension. Available in rigid or flexible configurations to suit different design requirements.
4. Cross Brace
Essential for maintaining transverse stiffness and stability, these components withstand horizontal forces while improving out-of-plane and torsional stiffness. Common configurations include one-word, K-shaped, X-shaped, and meter-shaped braces.
Applications & Features
Primary Applications
- Road Bridges
- Highway Overpasses
- Pedestrian Bridges
- Railway Bridges (for specific configurations)
Key Features
Steel arch bridges combine strength, versatility, and aesthetic appeal with features including durable deck systems, rehabilitation potential, and adaptive reuse capabilities.
