The response using the original set of ground motions was compared to the response using ground motions spectral matched to the FEMA P-695 SDC D max target response spectrum using an interactive computational tool. Seismic collapse safety was predicted using nonlinear response history analysis using FEMA P-695 methodology where the ground motion set was incrementally scaled with respect to the target response spectrum. The probability of building damage and downtime, as a function of ground motion intensity, was predicted using nonlinear response history analysis using the FEMA P-58 framework and sub-set of the FEMA P-695 Far Field ground motions, where the building response was correlated to structural and non-structural damage via Monte Carlo simulation. The comparisons showed that, for the buildings examined, spectral matching the FEMA P-695 Far Field ground motions had a significant effect on seismic collapse safety and performance predictions. The median collapse margin ratio was similar for both the original and spectral matched motions, but the dispersion was significantly reduced using spectral matching and led to increased collapse safety (reduced probability of collapse) and to reduced estimates of repair costs and downtime.
