RCC Structures Design
If the length of a combined footing for two columns l meters apart is L and the projection on the left side of the exterior column is x, then the projection y on the right side of the exterior column, in order to have a uniformly distributed load, is (where x̅ is the distance of centre of gravity of column loads).

y = L/2 - (l + x̅)
y = L/2 + (l - x̅)
y = L/2 - (l - x̅)
y = L - (l - x̅)
