The design of foundation of the building structure should be given prime attention because building foundation is in contact with the material i.e. soil which is highly complex, particulate, poly-phase, heterogeneous, and stress and strain level dependent. The real behavior of structure in contact with soil involves an interactive process beginning with the construction phase and ending with a state of balance within the structure and within the ground influenced by the structure. The analysis of such combined piled-raft foundation is very challenging because of complexities involved in the...
