The bridge foundation is the base of a bridge that transmits the loads from the substructure to the supporting strata. It must be sufficiently deep so that it is not affected by the scour caused by the flow in the river. The foundations of a bridge are particularly critical because they must support the entire weight of the bridge and the traffic loads it will carry.
The abutment is modeled in the below STAAD model using plate elements of size 0.5x0.5m. On application of soil loads at the top of the footing, it is not possible to be applied as pressure acting fully on the plate, since half of the foundation plate will be under the abutment wall.
To apply the soil loads acting on top of the foundation, the following procedure is followed.

A stiffness modifier is a modification factor that is generally used in the properties of cross section such as moment of inertia, torsion etc., aiding in reducing the stiffness in concrete sections to model cracked behaviour of concrete. The stiffness modifier is applied only on concrete structures as it cracks on loading.

Ellipse is a fundamental component of a conic section and shares many characteristics with a circle. An ellipse is oval in shape as opposed to a circle. An ellipse is a shape with an eccentricity less than one that symbolises a group of points whose distances from its two foci are added up to a fixed value. Everyday examples of the ellipse include the shape of an egg as well as the race track in a sports field.

A topographic map, or toposheet, depicts a three-dimensional terrain area in two dimensions. Since topographic maps display the landscape's horizontal and vertical location, they set themselves apart from other types of maps. It uses a combination of colour, symbols, labels, contour lines, and other graphical elements for visual representation.
