Contact Problem of Combined Footing Resting on Elastic Base

Abstract

CONTACT PROBLEM OF COMBINED FOOTING RESTING ON ELASTIC BASE The contact problem of combined footing resting on elastic half space, or stratified elastic base has been analyzed. Unlike simplified common assumptions and design methods of such foundation, here the analysis was carried over a two rigid footings connected by elastic flexible foundation beam, taking into account different characteristics of individual footing parts (rigid vs. flexible) and continuity conditions at their joints, with emphasis on their mutual interaction related to underlying soil load transfer. The numerical analysis has been performed by combined finite difference and boundary element method on the identical quadrilateral mesh.
