Example text

The result of a PSHA is a relationship of the mean annual rate of exceedance of the ground motion parameter of interest with each potential seismic source considered. See Kramer (1996) for further discussions of the types and methods used to conduct DSHAs and PSHAs. 2 is desired. 1 and its commentary. x Site-Specific Ground Motion Response Analysis: A sitespecific ground response analysis is used to determine the influence of local ground conditions on the design ground motions. The analysis is generally based on the assumption of a vertically propagating shear wave though more complex analyses can be conducted if warranted.
