Popis: The earthquake record shows that the territory of the Republic of Bulgaria is exposed to a high seismic risk due to local shallow and regional strong intermediate-depth earthquake sources—this fact is considered by the Code for design and construction in seismic regions in Bulgaria. Many modern sophisticated buildings and structures need comprehensive full time-history analysis at the design phase, which require modeling of the earthquake excitation via time histories. It is well known that the available strong motion database is quite limited, and therefore not representative of the real hazard—it clearly indicates the need of theoretically generated realistic seismic signals that can be used for further engineering analyses. The neo-deterministic seismic hazard assessment (NDSHA) procedure has been proven to be a very suitable one and supplies a significant database of realistic synthetic strong motions readily applicable for earthquake engineering purposes. A major advantage of the applied scenario-based procedure is the physically sound simultaneous consideration of the contribution of both the seismic source and the seismic wave pathway to the strong ground motion at each target site. In this study, we discuss the NDSHA applications in the study area: positive aspects and faced challenges.
