Structural Design of Steel Arch Bridge
The upper structure of steel arch bridge is primarily composed of arch ring, suspension rod (or arch column), tie rod, bridge beam and other components. Steel arch bridges have been used for centuries and continue to be a preferred choice for various bridge types.
Classification by Structure
- 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 arch bridges and simple system arch bridges. Composite systems feature tie arches, loser arches, and lange arches, 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 parameters including:
- Arch rib truss layout
- Arch axis configuration
- Vector span ratio
- Vault and arch foot height selection
- Bar section form and area
Key Structural Components
Arch Rib: The primary load-bearing member that mainly withstands axial pressure. Available in box, pipe, or truss type sections, with trussed arches offering superior weight efficiency and span capacity.
Boom: Transfers deck loads to the arch rib. Available as rigid (steel pipe/section) or flexible (high-strength wire) configurations, with various elevation arrangements including parallel, inclined, or mesh patterns.
Tie Bar: Bears the thrust of non-thrust arches through axial tension. Available in rigid or flexible configurations.
Cross Brace: Enhances transverse stiffness and stability. Common configurations include one-word, K-shaped, X-shaped, and meter-shaped braces, strategically placed for optimal structural performance.
Design Advantages
Steel arch bridges combine strength, durability, and aesthetic appeal with efficient load transfer capabilities. Their prefabricated construction allows for rapid assembly, while the structural design accommodates long spans and heavy loads across various applications.
