ck surface, topographic effects or other impedance boundaries) may require that analyses are also able to account for inclined waves. The staff will review the ground motions developed for each of the controlling earthquakes. Reference 12 and 13 contain a database of recorded time histories on rock for both CEUS and WUS. The staff will also review the simulation method (such as Monte Carlo) used to incorporate the variability in soil depth, shear wave velocities, layer thicknesses, and strain-dependent dynamic nonlinear material properties at the site. A sufficient number of simulations should be performed (at least 60) in order to define the mean and the standard deviation of the site response. 6.
