sponse analysis. When spectral values are calculated from the artificial time history, the frequency intervals at which spectral values are determined are to be small enough such that any reduction in these intervals does not result in more than 10 percent change in the computed spectra. Table 3.7.1-1 provides an acceptable set of frequencies at which the response spectra may be calculated. Another acceptable method is to choose a set of frequencies such that each frequency is within 10 percent of the previous one. 3.7.1-5 Rev. 2 - August 1989 Table 3.7.1-1 Suggested Frequency Intervals for Calculation of Response Spectra Frequency Range Increment (hertz) (hertz) 0.2 -
