Numerical analysis has been carried out on a sample wall, to study the influence of different parameters on its behavior. The aim of the work is to analyze the width and depth of the foundation of a typical residential structure by subjecting it to different loads and taking into account soil-structure interaction. A non-linear material model was employed to evaluate the contribution of shear depression in the subsoil and was subsequently used to improve the accuracy in simplification of dimensional complexity. The wall was analyzed in the longitudinal and cross-sectional directions to ensure calibration of the results. The effect of different types of timber framing in the longitudinal direction was assessed to evaluate optimal structural stability, along with recommendations for size of foundations based on loads from present day Eurocodes.
