This study aims to compare the seismic risk estimates obtained based on Probabilistic Seismic Hazard Assessment (PSHA) employing both the traditional ergodic approach and a partially non-ergodic site-and source-specific approach. Two different partially non-ergodic ground-motion attenuation relationships available for Turkey are adopted for this purpose. For four sites located in Turkey under the predominant influence of Eastern Anatolian Fault, seismic hazard is estimated using both the traditional ergodic approach and partially non-ergodic approach. For each site, the hazard estimates of the two PSHa approaches are utilized to select and scale two sets of hazard-consistent ground-motion records according to the Turkish Design Princible for Buildings Subjected to Earthquakes (2018) that are employed to estimate the response of eight ductile structures representing the low- to mid-rise reinforced concrete buildings is Eastern part of Turkey. The seismic responses of these reinforced concrete structures are estimated by performing nonlinear response history analyses according to the Turkish Design Principles for Buildings Subjected to Earthquakes (2018) regulations.
