Pile Cap - dipak.jain - 11-04-2014

Pile Cap

1. A structural member placed on, and usually fastened to, the top of a pile or a group of piles and used to transmit loads into the pile or group of piles and, in the case of a group, to connect them into a bent. Also known as a rider cap or girder.

2. A masonry, timber, or concrete footing resting on a group of piles.

3. A metal cap or helmet temporarily fitted over the head of a precast pile to protect it during driving. Some form of shock-absorbing material is often incorporated.



The functions of a pile cap are:


1. To distribute a single load equally over the pile group and thus over a greater area of bearing potential
2. To laterally stabilise individual piles thus increasing overall stability of the group.
3. To provide the necessary combined resistance to stresses set up by the superstructure and/or ground movement.
