TMK have adopted a set of policies (“rules”) which place “lower-bound” limits on the size of footings and the reinforcement which can be specified for them. Because it is desirable to make bearing pressures uniform throughout the footing, the centroid of the footing should be made to coincide with the centroid of the column loads to attempt to prevent uneven settlements. Storey number Storey numbers are given to the portion of the building between two successive grids of beams.
