Step -1: Defining size of footing: Loads on footing comprise load from column, self weight of footing and weight of soil above footing. The grade of concrete should be M30 and grade of steel should be Fe415. The safe bearing capacity (SBC) of soil is 300 kN/m2.
Loads delivered from this column to the foundation are Vertical Load: 1000 kN and Uniaxial Moment: 100 kNm
As for example, take an isolated footing for an RCC column having size 450mm x 450mm.
