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 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.

Simple system arch bridge: Only the arch ring is the main force component, and the simple system is a thrust arch structure, and the thrust of the arch is directly borne by the pier or foundation.
Combined system arch bridge: Carriageway beam and arch combination, common force.

Main Arch Structure

Steel arch can be designed into truss arch, box arch, plate arch. Many truss arch bridges are built in foreign countries, and more than ten steel box arch bridges are built in China. Truss arch bridge is an important form of rigid arch bridge with large span.

The main arch of truss arch bridge along the span direction: equal height, variable height.

Overall Design Parameters

The overall design parameters of long-span steel truss arch bridge are:

Layout of arch rib truss
Arch axis
Vector span ratio
The selection of the height of the vault and arch foot
Boundary conditions
Bar section form
Bar section area

Main Components of Steel Arch Bridge

1. Arch rib
The main load-bearing members of the structure mainly bear axial pressure, but also bear part of the bending moment, and the eccentric compression members are mainly compressed. 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.

2. Boom
It is a force transfer component, which transfer the deck load to the arch rib of the bearing member, 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, which can only be stretched, convenient construction and beautiful appearance.

Elevation arrangement of the boom
Boom spacing is the span length of the longitudinal beam of the carriageway, and it usually takes equal spacing. According to its layout in the arch plane, the boom is divided into: parallel vertical boom, inclined boom, mesh boom. According to the placement quantity the boom is also divided into single boom, double boom.

3. Tie bar (beam)
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.

4. Cross brace
In order to ensure the transverse stiffness and stability of the two arch ribs and withstand the transverse horizontal forces acting on the arch ribs, bridge deck and boom, it is necessary to set the transverse supports. The cross brace can greatly improve the out-of-plane stiffness and torsional stiffness of the whole bridge, but basically do not improve the in-plane stiffness.

Basic requirements:
It is arranged on the arch section outside the scope of the clearance height of the bridge floor. The width of the brace should not be less than 1/15 of the length.

Structural form of the cross brace:
The common ones are "one-word brace", "K-shaped brace", "X-shaped brace", "meter-shaped brace". The position of the cross brace corresponds to the position of the lifting point, and is symmetrical to the odd arrangement of the arch roof.

5. Arch post
The stand column is used for the upper bearing part of the upper bearing arch bridge or the middle bearing arch bridge, and is the force transfer structure between the bridge floor system and the main arch rib.

Overall Design Parameters of Arch Rib

The main design parameters of long-span steel truss arch bridge are as follows: beam span ratio, selection of arch axis, choice of vault and arch height.

Rise span ratio
Mainly according to the topography of the bridge site, geological conditions, bridge clearance requirements and other factors to determine. The common range of arch rib span ratio is 1/4~1/7, the span ratio of steel truss arch bridge is usually 1/4~1/5. The smaller the span ratio is, the greater the horizontal thrust of arch foot is. When geological conditions are poor, a larger vector to span ratio can be used to reduce horizontal thrust.

Axis of arch
The ideal arch axis is consistent with the pressure line on the arch, and the section only bears the pressure without bending moment, which can make full use of the material strength. Common forms of arch axis: arc line, quadratic parabola, catenary.

Arch rib vault and arch foot height selection
According to the variation of arch rib height, it can be divided into equal height arch rib and variable height arch rib. When the span is large, the variable height arch rib is used to adapt to the internal force distribution of arch rib and save the engineering amount.

The function of the transverse connection is to link the arch plates of the rigid frame into the whole common force and ensure the transverse stability. In order to simplify the structure, the transverse connection can be prefabricated transverse beams or transverse partitions, and the spacing is arranged according to the size of the span.

Steel Arch Bridge Features

The steel arch has magnificent appearance, large span capacity and high carrying capacity. The maximum span of steel arch bridge is 552m which has been built.
Arch Shape: The most prominent feature of steel arch bridges is their arch-shaped design.
Steel Construction: Steel arch bridges are constructed using steel as the primary material.

Applications of Steel Arch Bridge

The thrust of tie arch is digested by internal system, which is suitable for long span rigid arch bridge. The Roser arch with rigid arch and rigid beam is suitable for heavy-duty railway bridge; The Rangel arch with rigid beam and flexible arch is suitable for the double-deck arrangement of both roads and railways.

Rehabilitation or Replacement Projects
It's worth noting that the specific application of a steel arch bridge depends on various factors, including the site conditions, design requirements, budget, and engineering considerations.
