eismic response analysis. When spectral values (e.g., spectral accelerations) are calculated from the artificial time history, the frequency intervals at which spectral values are determined are to be sufficiently small. Table 3.7.1-1 (below) provides an acceptable set of frequencies at which the response spectra may be calculated. Table 3.7.1-1 Suggested Frequency Intervals for Calculation of Response Spectra Frequency Range (hertz) Increment (hertz) 0.2 - 3.0 0.10 3.0 - 3.6 0.15 3.6 - 5.0 0.20 5.0 - 8.0 0.25 8.0 - 15.0 0.50 15.0 - 18.0 1.0 18.0 - 22.0 2.0 22.0 - highest frequency of interest
