Wall footing
A wall footing or strip footing is a continuous strip of concrete that serves to spread the weight of a load-bearing wall across an area of soil. It is the component of a shallow foundation.
Wall footings carrying direct vertical loads might be designed either in plain concrete or in reinforced concrete. Since a wall footing deflects essentially in one way, it is analyzed by considering as a strip of unit width and its length. The critical sections for calculating maximum bending moments in different types of wall footing are given in according to the below figure.
