Abstract

It is illustrated that the earthquake ground motion can be properly evaluated by combining Fourier amplitude based on the ω-squaremodel and Fourier phase of the recorded one. The parameters of seismic moment and corner frequency identified by the proposed method are in harmony with the values presented in the previous papers. It is shown that the response spectrum of a wave synthesized by replacing Fourier phase with that of a different record, whose distribution shape of the phase difference is analogous to the original one, is comparable to the result of the original wave. This finding suggests that a simulated earthquake ground motion, which exhibits a realistic response spectrum, can be generated by the proper selection with respect to the phase difference characteristics.
