ABSTRACT
Macroelement is a space constituting coupled system of forces from super structure, soil half space and the boundary between them. The complex behaviour of soil structure interaction can be conceived by the use of elastoplastic strain hardening macroelement constituting the interaction between different structural forces acting on foundation. The use of granular model like macroelement constituting of few constitutive parameter and capable of delivering high ended results of Soil structure interaction reduces the ambiguity of model response and the complexity in the analysis of the system under consideration. Figure 1. shows the pictorial representation of macroelement consisting of forces from structure and the arbitrary elasto-plastic region of soil under consideration of macroelement.
