A simple discrete model is developed to represent the nonlinear behavior of the soil around a short rigid pier foundation, When it is subjected to large Lateral forces or large overturning moments. The soil resistances include lateral soil resistance, bottom vertical resistance, bottom frictional resistance, bottom moment resistance and frictional resistance on the sides of the pier. All these soil resistances are modelled using a nonlinear soil spring concept. Comparison of the results using the model with full-scale experimental results show good promising characteristics.
