any pressure to the soil. The strap, assumed to be infinitely stiff, serves to transfer the column loads on to the soil with equal and uniform soil pressure under both footings.
Fig. 2.7 shows the strap footing for two columns A and B. Column A is so near to an existing wall that the footing of the wall does not permit the independent footing of column A lo spread out towards the wall, though it has freedom in other directions.
