The Bridge provides cohesion between various isolated sections of a world, two ocean banks, or portions of two nations. A Bridge is a technical wonder typically used to move through any kind of obstacle that may delay people’s lives. From the very beginning, engineers have tried to win over nature and have therefore created a bridge system that can be used to conquer the natural obstacles described above.
Types of Bridges
- Suspension Bridges
- Slab Bridges
- Box Girder Bridges
- Cable-Stayed Bridges
- Truss Bridge
- Arch Bridges
Below is a brief description of these styles of bridges.
Suspension Bridges: Long spans can be provided in suspension bridges that are necessary in many cases. This allows the builder the right to use a cable to provide a long span. The foregoing are the basic components of a bridge suspension.
Slab Bridges: It is the most popular bridge form. Using anywhere that the duration isn’t that big.
Box Girder Bridges: It’s a separate box type girder than I usually girder and it can comfortably handle more torsion. This bridge form contains the top deck, the vertical network, the bottom slab. You can split the box girder bridge into three basic categories:
- Single-cell box.
- Multicell box.
- Box with struts supporting a cantilever deck.
Cable-Stayed Bridges: The suspension bridge has a lot of similarities. But between a suspension bridge and a cable-stayed structure, there are few variations. The bridge carries mainly the vertical loads acting on the girder in this case. The stay cables are intended to provide the girder with intermediate support and help span a long distance.
Truss Bridges: Two force member bridges are made of steel with only tension and compression. In this system, no bending moment is permitted. Truss’s most robust design form is triangular.
Arch Bridges: The bridge of the arch exists mainly in compression. Uses a torsional rigidity aerodynamic device.
Stiffening Girder/Trusses: Supporting and distributing moving vehicle loads are longitudinal structures. Secure structural aerodynamic stability.
Main Cables: Hanger cord links the main cables to the girders. Such hanger ropes pass loads to the central cables from the girder. These main cables have the main function of carrying such loads to the key towers.
Main Sections of the Bridge
There are various types of bridges. Different types of bridges have different parts. FOllowings are a bridge’s main parts:
- Rail Track
- Pile
- Abutment
- Girder
- Deck
- Pier
A short description of each part is given below to give a preliminary idea of these bridge parts.
Rail Track: Road traffic is normally the main vehicle on the bridge, but it is the extra component if the train has to be passed through that bridge rail track.
Pile: The pile is a fundamental component of the pier bridge. The foundation of the pile type is generally required when the upper layer of soil is loose. The depth of the pile depends on the layer of soil. The pile is usually extended to some depth into the hard soil layer in order to find the hard soil layer that will make the structure stable.
Abutment: The support provided at the two ends of a bridge is known as an abutment.
Girder (Box or I-joist)
The girder is used in the bridge just like the pillar. It can be I-joist and Box with two forms. Due to their form, this name was given. I-joist form of girder is commonly used in bridges. Box girder can be prefabricated or set in place and is typically in the pre-stressed state.
Deck: A deck is a fundamental part of any bridge from one side to the other for passing vehicles, goods, people, etc.
Pier: Pier is the part of the compression that remains above the pile and stabilizes the frame. Pier offers ranging at intermediate points in general. Piers have two main functions to perform:
- Move of vertical loads from the superstructure to the base.
- Resisting the bridge-acting horizontal forces.
The gap to the pier for the bridge is the width. Water pressure is the additional lateral weight on the bridge.
