Multiple bents form the foundation for the substructure. Caps are often made of very heavy concrete to give maximum strength to the upper part of the bridge.īents: When piles and caps are set together they are called bents. They are also known as pile caps as they are placed right on top of the pile foundation. For bridges on rivers, scouring is also considered before the bridge is designed.Ĭaps: Caps provide additional load transferring capacity to the piles. The material and design of a pile depend on several factors such as soil type, ground instability and load bearing capacity constraint. The piles help the weight and stresses applied by the bridge to be transmitted evenly through the ground making it stable and strong. Piles: Piles are usually laid to give support to a bridge and make up the initial foundation. Let’s look at the main parts of a bridge in more detail and consider the components that make up the three core areas: The Foundation Then the sub-structure is made to give support for the heavy superstructure above it, which is actually used as the road or walkway Main Parts of a Bridge © 2017 EngineeringClicks Main Parts of a bridge When building a bridge, the construction starts with laying the foundation.
