Figure 11. Samples of 20 response spectra from magnitude 6.5 earthquakes with a
source-to-site distance of 8 km. The simulated spectra use means and variances
from Abrahamson and Silva (1997).
(a) Simulated spectra using correlation coefficients equal to zero between all
periods. (b) Simulated spectra using correlation coefficients equal to one
between all periods. (c) Simulated spectra using correlation coefficients from
equation (9). (d) Real spectra
from recorded ground motions with magnitude 
6.5 and distance 8
km.
