Abstract. When subjected to dynamic loads, foundations oscillate in a way that depends on the nature and deformability of the supporting ground, the geometry and inertia of the foundation and superstructure, and the nature of the dynamic excitation. Such an excitation may be in the form of support motion due to waves arriving through the ground ...
