(i) CI. 34.2.3.1 of IS 456:2000, The bending moment at any section shall be determined by passing through the section a vertical plane which extends completely across the footing and computing the moment of the forces acting over the entire area of the footing on one side of the said plane.
(ii) CI. 34.2.3.2 of IS 456:2000, The greatest bending moment to be used in the design of an isolated concrete footing which supports a column. pedestal or wall shall be the moment computed in the manner prescribed in 34.2.3.1 at sections located as follows:
- At the face of the column, pedestal, or wall, for footings supporting a concrete column, pedestal, or wall;
- Halfway between the center-line and the edge of the wall, for footings under masonry walls;
- Halfway between the face of the column or pedestal and the edge of the gusseted base, for footings under gusseted bases.
