In the case where a wall sits on the intersection of two continuous footings, as shown in the following figure, 100% of the load on the wall will be placed on the foundation that completely supports the wall. The intersecting foundation receives no load from the wall.

In the case where a wall sits on the intersection of two continuous footings, as shown in Figure below, 100% of the load on the wall will be placed on the foundation that completely supports the wall. In order to determine the load that gets applied to any other footing that intersects a wall end (the perpendicular footing in the case of Figure below), the forces on the wall are resolved into two end reactions considering the wall as a simple beam. The full value of the calculated end reaction will be applied to the off-wall footing at the point of intersection.
