Component of Bridges in Civil Engineering
Bridge: – As we know that, a Bridge is a structure providing passage to cross obstacles like a stream or river or low ground etc without closing the way beneath. The bridges made to provide passage for a railway, a road, a canal or a pipeline etc.
Bridge Engineering: – It is a part of civil engineering which deals with the construction, maintenance as well as design related to Bridges.
What is Bridges?
- The bridge is a structure which covers a gap.
- Generally, bridges carry a road or railway across a natural or artificial obstacle such as a river, canal or another railway or another road.
- A bridge is a structure corresponding to the heaviest responsibility in carrying a free flow of transport and is the most significant component of a transportation system in case of communication over gaps for whatever reason such as aquatic obstacles, valleys, and gorges etc.
Component of Bridges
- Sub Structure.
- Super Structure.
Substructure: The Lower Most part of bridges which supports the entire structure made from abutments pier etc. including superstructure is called sub-structure.
Components of Substructure
- Wing Walls
Foundation:- It is the lowermost part of the bridge structure. The main function of the foundation is to take a load of the superstructure and transfer the all load to the subsoil through foundations.
Piers: – It is an upright support or superstructures as well as structures, for example, an arch and bridges.
Wing Wall: – A wing wall is a smaller wall which is attached or next to a larger wall or structure.
Abutments:- Abutment is a type of column which is constructed to approach road of a bridge
It is that part of bridges over which the traffics moves safely. It consists of Roadway, Girder, and Arches etc. Over which road is supported
Note: – The basic function of the superstructure is to provide carriageway.
Components of Sub Structure
- Any structure above the bearing
- Wearing surface
