Therefore, to determine the settlements, it is necessary to know: the course of vertical stresses 03c3z with depth. The settlement-generating base stress 03c31 = 03c30 - 03b3 2022 h must be used, taking into consideration the stress reduction by the excavation unloading for the embedment depth of the foundations.

Differential Foundation Settlement Differential settlement is a condition wherein a building's foundation settles unevenly, often leading to structural damage. Consequentially, the frame of the building may become distorted, floors may slope, and windows and doors may become stuck.

To determine the settlement under a footing of given size loaded to the load per sq. ft. for which the curve is prepared, determine from the curve the settlement per unit of column load on the footing of the size required under the column load, and multiply by the total column load carried by the footing.
