Corbel is a short structural element that cantilevers out from column/wall to support load.Generally, the corbel is casted monolithically with column/wall.
There are several typical modes of failure in the corbel. The most common of which are yielding of the tension tie, failure of the end anchorages of the tension tie, either under the load point or in the column, failure of the compression strut by crushing or shearing, and local failures under the bearing plate.
