Explain about the footings how it is transmit loads.

Footings are generally the lowermost supporting part of the structure known as sub-structure and are the last structural elements through which load is transferred to foundation comprising soil/rock. Structural elements transfer the applied loads from one part of the building to the other. These are in turn transmitted to the foundation which transfers it to the underlying soil/rock. The footing transmit the super impose loads on the foundation so that the safe bearing capacity of the underlying foundation material, is not exceeded.
