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. The wall foundation is usually designed regarding as the continuous plate. Actually, it is difficult to construct according to the designed specification, the wall foundation is constructed by separating to some panels. Any structural fastener does not connect the joints to each other. The wall foundation behaves as uniform plate for long or small lateral load affects on the foundation. The joints could be cracked and separated as the severe earthquake would occur. If the wall foundation keeps uniform body for severe earthquake, the fatal destruction may happen by the local shear stress concentration. The pile-like split wall foundation might be better foundation system than usual wall foundation. It should be investigated to evaluate the seismic safety of foundation and structures. This paper described the dynamic response characteristics of composite foundation of wall and pile by using rigorous 3-D FEM.
