This paper is intended to clarify the difference of building function loss possibilities which depend on the realization way of the variation and/or inter-period correlation in the response spectra of ground motions. The authors prepared some cases of GMs sets shown in following. The response analyses of a simple RC structure were conducted for each cases and the damage frequencies of equipment system were compared. case(n): simulated GMs which have no variation in response spectra. case(p): simulated GMs which have the same variation in response spectra with case(r), while the inter-period correlation coefficient is 1.0.. case(c): simulated GMs which the same variation with case(r) and the modeled inter-period correlation of case(r) in the response spectra. where, case(r) is the set of original ground motions.
