METHODS FOR ACHIEVEMENT UNIFORM STRESSES DISTRIBUTION UNDER THE FOUNDATION

Foundation response is a complex interaction of the foundation itself, the superstructure above and the soil. That interaction may continue for a long time until final equilibrium is established between the superimposed loads and the supporting soil reactions. Foundation receives loads from the superstructure through columns, walls or both and act to transmit these loads into the soil. In many projects superstructure has separated study in which soil simulated as springs with sub-grade reaction which mean that soil is one layer with liner reaction neglect settlement of soil, types and properties of soil layers, underground water table and surrounded structures. The same happened in preparing the soil investigation and the soil report for any project which take only the loads transferred from the structure or assumed uniform distribution and do not take into consideration the effect of structure elements stiffness or the reaction between the foundation and the other elements.
