A new critical excitation method is developed for a damped linear elastic structure supported by a sway-rocking system. The input energies to the sway-rocking model and to the super-structure only during an earthquake are introduced as a new measure of criticality. It is shown that the formulation of the earthquake input energy in the frequency domain is essential for solving the critical excitation problem and deriving bounds on the earthquake input energies. It is demonstrated that the analysis of the bounds on the input energies to the sway-rocking model and to the super-structure only is useful for understanding the ratio of the input energy to the super-structure to that to the total system in various soil conditions.
