Reinforced concrete foundations, or shoes, convey loads of a structure to the support ground. The shoes are designed based on the nature of the load, the properties of the shoe and the properties of the soil. The shoes are subjected to lateral loads or tipping moments, in addition to vertical loads. These types of loads are typically seismic or wind loads. Lateral loads or tipping moments result in non-uniform soil pressure under the base, where the soil pressure is greater on one side of the base than on the other. Non-uniform ground support can also be caused by a foundation pedestal that is not in the center of gravity of the foot.
