Steel arch bridges have both composite system arch bridges and simple system arch bridges. There are several kinds of combined system arch Bridges, such as tie arch, loser arch, lange arch and other combined system arch bridges.
- 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 the boom: parallel vertical boom, inclined boom, mesh boom
Rigid frame arch plates can be constructed by cast-in-place or prefabricated installation, which should be determined according to transportation conditions and installation capacity, and most of them use the latter at present.
- Simple system arch bridge: Only the arch ring is the main force component, and the simple system is a thrust arch structure
- Combined system arch bridge: Carriageway beam and arch combination, common force
The main load-bearing members of the structure mainly bear axial pressure, but also bear part of the bending moment. According to the form of section is divided into: box, pipe, truss type. Trussed arch rib has light weight, greater span capacity and good economy.
A force transfer component that transfers the deck load to the arch rib. The boom is mainly an axial tension member. The rigid boom is made of multi-purpose steel pipe or section steel and can withstand pressure. The flexible boom is made of high-strength steel wire bundle or steel strand.
For the non-thrust arch, the thrust of the arch is borne by the tie rod, and the tie rod bears the larger axial tension. Divided into: rigid tie rod, flexible tie rod.
Ensures the transverse stiffness and stability of the two arch ribs and withstands the transverse horizontal forces. Common structural forms: "one-word brace", "K-shaped brace", "X-shaped brace", "meter-shaped brace".
- Flexibility: Can be shaped, bent, and fabricated into various forms
- Durability: Withstands harsh environmental conditions
- Ductility: Can undergo large deformations and absorb energy before failure
- Deck and Roadway for vehicle and pedestrian traffic
- Abutments and Piers to support the arch structure
- Various configurations for different applications
