What Is Abutment?

It used at the ends of the bridge to retain the embankment and also carry the vertical and horizontal loads for the bridge superstructure to the foundation. The abutment is usually constructed from concrete which can support the heavy load of the vehicles.

Function Of Abutment:

1. To transmit the load from the bridge superstructure to the underlying sub-soil.

2. To provide a final formation level to the bridge superstructure.

3. To retain the earth’s pressure of embankment of the approaches.

Types Of Abutment:

1. Abutment with wing walls.

2. Abutment without wing walls.

What Is Pier?

Generally, Pier is the type of a column which are constructed between the two abutments in the bridge which supports the load of the superstructure of the bridge. Piers have transferred the load of the slab beam and vehicles to a foundation.

Function Of Pier:

The function of a pier is to transmit the load from the bridge to the underneath sub-soil.

Types Of Pier:

Depending upon the type of superstructure, sub-soil conditions and the construction procedure of the bridge, the pier can be classified into the following two types:

1. Solid piers

2. Open piers.

What is Column?

The column is a vertical structural member designed to transmit a compressive load. Column transfers the load from the superstructure to the substructure. Columns are supported by fixed ends at both ends.

Types of Column 

1- Single Column Bent

2- Two Column Bent

3- Multiple Column Bent
