Abstract:The methods are further applied to generation of Uniform Hazard Earthquake Response Spectrum and Ground Motions. A record-based methodology is proposed and demonstrated by an example at Los Angeles. The resulting UHRS compare well with those of USGS and SAC. The method does not rely on theories or empirical models, such as the rupture models, attenuation relation, Fourier spectrum and it preserves the variability across the ensemble. It uses only free-field records from the local region with similar seismicity environment and does not scale the records, consequently, the UHGM are truly site-dependent. It considers the strikes of the major faults near the site and the difference between the fault normal and fault parallel directions, and provides UHRS and three-component UHGM in three orthogonal directions.
