Description:
The basic seismic load parameters for the upcoming national design regulation for DIN EN 1998-1/NA result from the reassessment of the seismic hazard supported by the German Institution for Civil Engineering (DIBt). This study is based on a comprehensive involvement of accessible uncertainties in models and parameters. It includes the provision of a rational framework for integrating epistemic uncertainties and aleatory variabilities in a comprehensive way and incorporates significant improvements. It is based on updated and extended databases, robust methods to evolve sets of models representing epistemic uncertainties and a selection of latest : ground shaking prediction models. The output specifications were designed according to the user oriented needs: Seismic load parameters are calculated for rock conditions, mean return periods of 475, 975 and 2475 years and delivered as uniform hazard spectra, seismic hazard maps for peak ground acceleration, spectral response accelerations and macroseismic intensities as mean, median and 84 % quantile. Examples of some elements of the input and a few basis results are shown.
