WebEccentric loads are those whose line of action is offset from the axis of a member. Moreover, the distance between the geometric axis and line of action of the force (P) is the eccentricity (e) of the load as the diagram below shows. Courtesy: hkdivedi.

WebThe function of a footing or a foundation is to transmit the load form the structure to the underlying soil. The choice of suitable type of footing depends on the depth at which the bearing strata lies, the soil condition and the type of superstructure. ...
