In seismic design, we should appropriately take into account of uncertainties in seismic inputs. We presented a worst-case analysis based on a random sampling approach with order statistics. In this study, we investigate the applicability of the method to design seismic motions, which of acceleration response spectrum at the engineering bedrock surface is specified by a target spectrum, incorporating uncertainties of their ground-surface characteristics. We present a probabilistic prediction method of worst-case response of moment-resisting steel frames under such uncertain seismic inputs.
