A Design Ground Motion Library (DGML) is being developed that will contain selected recorded acceleration time histories considered to be
suitable for use by engineering practitioners for the time history dynamic analysis of various facility types in California and other parts
of the Western United States. The DGML will include: (1) the electronic library of selected time histories and their associated ground motion
parameters and supporting information on the earthquake source, travel path, and site characteristics; and (2) detailed guidelines for forming
and scaling sets of time histories for applications. The characteristics of the seismic environment, including earthquake magnitude, faulting
mechanism, source-to-site distance, nearfault directivity conditions, and site conditions, and the damaging characteristics of time histories
are being incorporated into criteria for selecting and binning records for the library.
