This article presents the method of determination of friction parameters for soil structure interaction with and without slide joints in the subsoil of structures. The results for constant and nonlinear distribution of C1x, C1y parameters are compared and derived friction parameters have been used for the FEM calculation of the stress condition of the real foundation structures.

Manual Calculation

In spread footings, the rotational spring constants, which represent the soil-structure interaction, play an important role in the structural analysis and design. To assign the behaviour of soil, which is generally represented via Winkler-type tensionless springs, necessitates time consuming iterative computing procedures in practice. In this study, a straightfor­ward approach is proposed for the soil-structure interaction of rigid spread footings especially subjected to excessive eccentric loading. By considering the uplift of footing, the rotational spring constants of those type footings under axial load and biaxial bending are easily attained through the proposed simplified formulations. Since these formulations enable manual calculation, iterative computer efforts are not required. The formulations under consideration can be applicable to sym­metric and non-symmetric rigid spread footings. The numerical results of this study are verified with SAP2000.
