・Fourier amplitude spectrum is calculated by Fast Fourier transform(FFT).
・Fourier amplitude spectrum is calculated with no noise filtering.
・Maximum Response is calculated with no noise filtering.
・Average(gal) in the document is the value after minus offset.
※Caution:Calculated directly from original uncorrected accelerogram data minus offset.
※Offset is the average of all original uncorrected accelerogram data.
