Numerical prediction of response of circular footings on structured soils

Dr. Mohammed Kabirul Islam and Kamruzzaman Talukder


The Structured Cam Clay (SCC) model was incorporated in a finite element program to study the influence of soil structure in the settlement of a circular footing. The SCC model has three parameters in addition to Modified Cam Clay. These parameters show the effect of structure on the stress-strain response of soils. A parametric finite element analysis was conducted to investigate the effect of each of these parameters on the pressure-displacement response of a circular footing resting on structured soil. The investigation shows that principal effect of SCC parameters is on the plastic slope of the pressure displacement response of the footing resting on structured soil.
