• A simplified 3DOF model is suggested as the soil-structure system by replacing the structure by a SDOF model using the modal coordinates of the fixed-base structure. The modal parameters of the system are evaluated parametrically through the eigenvalue analysis. The derived formulations allow the use of hysteretic damping model as the material damping in the soil and structure which is a more realistic model than the commonly used viscous one. The frequency dependency of the soil impedances can also be handled by the model through a few loops of iteration. The model is applied for the case of building on surface of half-space soil medium and satisfactory results are achieved in comparison to the results of more rigorous models and also code provisions. The model is also easily applicable for more complicated cases such as buildings on layered half-space soil media.
