Question

What is the amount of load usually coming from the bridge to abutment?

Answer 1

in  engineering, abutment refers to the substructure at the ends of a bridge span or dam whereon the structure's superstructure rests or contacts.[1] Single-span bridges have abutments at each end which provide vertical and lateral support for the bridge, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments.[2] Dam abutments are generally either side of a valley or gorge but may be artificial in order to support arch dams such as Kurobe Dam in Japan.

Answer 2

Explanation:

Abutments support the ends of the bridge and transfer the loads from the superstructure into the ground. The abutments also support the bearing devices and the backwalls. Abutments are usually constructed of concrete.
