Probability estimation of regional seismic hazard for Isparta city center and analysis of the alluvion soil with an equivalent linear/nonlinear dimensional finite element model

In this study, deterministic and probabilistic seismic hazard analyzes were made for the province of Isparta. Within the scope of this analysis, 208 seismic sources were identified in the circular area with a radius of 200 kilometers, which was drawn by accepting the Isparta city center as the reference point. The magnitude values that these seismic sources can create depending on the fault lengths have been determined. After the calculation of these magnitude values, the peak acceleration values of the bedrock in Isparta province were obtained by using the many attenuation relations relations obtained as a result of different studies. In the light of these acceleration data obtained, probabilistic seismic hazard analysis for Isparta province was made and the probability of exceeding certain acceleration values within 50, 475 year periods was calculated. In the continuation of the study, the analysis program named DEEPSOIL, which can perform linear, equivalent linear and non-linear ground response analysis in one direction, was introduced and all the information required for the use of the program was discussed within the scope of the introduction. Finally, the seismological structure of Isparta province has been examined, soil properties and parameters have been determined and soil amplification and ground peak acceleration values for Isparta province have been obtained through the DEEPSOIL program.
