Abstract:

Natural soils are often comprised of separate layers. Foundations of engineering structures are designed to transfer and distribute their loading to the underlying soil and/or rock. Therefore, the designer must ensure that the structure does not suffer from excessive displacements. In this research, it is intended to make a generalized numerical solution through a computer program has written in MATLAB to analyze a multilayered nonhomogeneous (Gibson-type) soil, where the stiffness contrast exists between layers, by determining the displacements and stresses under strip footing during applied incremental loading sequence. This research presents a plane strain two-dimensional finite element method. In this method, the soil is divided into several 4-node quadrilateral elements. The general behavior of a multilayered soil profile and the influences of strip foundations resting on soils having homogeneous (constant modulus with depth) to Gibson-type (linearly increasing modulus) profiles are studied. The influences of foundation size and embedment, incremental loading, and soil stratifications are considered in this study.
