Abstract: In this paper, we investigated how to utilize the small-strain stiffness in order to estimate the settlement of shallow foundations on granular soils. For this purpose, a power law equation between normalized shear modulus and shear strain was presented. Based on theory of elasticity and proposed equation, a new method in term of small-strain stiffness was suggested to estimate the immediate settlement. In order to evaluate the proposed method, a series of case history included plate and footing loading tests and seismic geophysical tests was studied. These field measurements are compared to the predicted values. The result indicated that the proposed method in this study can be effectively used to predict the settlement of footing on granular soils and that were more accurate than the SPT or CPT based predictions.
