The foundation system is determined depending on the type of structure and soil characteristics. When the bearing layer exists in deep, the pile foundation is generally employed. The wall foundation is combined, when the more rigid performance of foundation is required. Although it is basically prohibited, the composite foundation is sometimes employed as the bearing layer has steep slope condition. The structure on the composite foundation is subjected to the rotational and torsional input motions not only the horizontal motion. The rigorous method should be applied to evaluate the seismic safety of foundation and structures. The improvement of convergence problem due to the internal damping make the explicit method be more useful to the dynamic analyses for the large 3-dimensional models. The developed implicit-explicit hybrid analyses method is applicable to the soil structure interaction models and can predict the dynamic behavior of complex composite foundations. The nonlinear analyses of RC building on the composite foundation is carried out by the proposed 3-dimensional analysis method
