| Abstract: | Response spectral moments are useful for system reliability analysis. Usually, spectral moments are calculated by the frequency
domain method. Based on the time domain modal analysis of random vibrations, the authors present a new method for calculating
response spectral moments through response correlation functions. The method can be applied to both classical and non-classical
damping cases and to three kinds of random excitations, i.e., white noise, band-limited white noise, and filtered white noise.
