Abstract

Within the scope of this study, design spectrum parameters (constant acceleration region, corner periods and site factors) are proposed, depending on probabilistic seismic hazard analyses conducted in a region located in a part of the North Anatolian Fault Zone. The outcomes are obtained for different site conditions and return periods. Two different seismic source models which are area based source, and fault and locational seismic source models are used for probabilistic seismic hazard analyses. The ground-motion characterization is handled by selecting the ground-motion prediction equations that best reflect the seismic excitations around the investigated region. The computation of constant acceleration region corner periods and site factors are based on the empirical relationships that depend on the PGA or spectral accelerations at T = 0.2 s and 1.0 s for rock sites.
