INTERACTION ANALYSIS OF STRIP FOOTING RESTING ON A NONHOMOGENEOUS ELASTIC MEDIUM

In this paper, a plane stress solution for the interaction analysis of strip footing resting on (i) a non-homogeneous elastic half-plane and (ii) a non-homogeneous elastic layer resting on a rigid stratum has b een presented. The analysis has been done using a combined analytical and FEM method in which the discretization of the half-plane is not re quired and thereby minimizes the computational efforts considerably. T he contact pressure distribution and the settlement profile for the se lected cases of varying modulus half-plane, which has more relevance t o foundation engineering, have been given. Experimental verification t hrough a photoelastic method of stress analysis has been carried out f or the case of footing on Gibson elastic half-plane, and the contact p ressure distribution thus obtained has been compared with the theoreti cal results.
