WORK DONE BY EARTHQUAKE GROUND SHAKINGS UPON VARIOUS TYPES OF DYNAMIC SYSTEMS

抄録（英）：
With relation to the amount of earthquake energy fed into structures, an instructive set of mathematical formulas is presented in a novel fashion. The scope of formulations extends far to multi-component inputs of ground shaking as well as to a variety of multi-DOF systems. Upon deleting the separable factor of oscillation mode, a close relationship with the Fourier amplitude spectrum is shown to feature the spectral representation of the available energy in a ground shaking. In particular, the results indicate a new procedure for the time-dependent frequency analysis of multi-dimensional earthquake motions by means of the tensorial expression of the work done upon oscillators.
