Özet
Together with the ever-increasing number of global and local Ground Motion Prediction Equations (GMPEs) and thecomplexity of the functional forms, incompatibility problems arise in the selection of the most appropriate GMPE for a specificlocation. Associated with the incompatibility issues, practitioners face a compromise over the precision of prediction becausethe functional form of the used GMPE that might be developed by considering influential parameters, which might not beavailable for the considered location. Hence, a modification is required to adjust the considered GMPE to local conditions byusing the local ground motion data. The sensitivity of the parameters of the selected GMPEs to the local seismic propagationpatterns can be determined only after the adjustment. Together with the attempts to solve the incompatibility and sensitivityproblem, the selection of the most appropriate GMPE becomes the selection of the most suitable functional form.The aim of this study is to select the most appropriate GMPE form for Eskişehir through the guidance of the above statements.A number of GMPEs are selected according to the criteria of wider utilization and recognition. All the candidate GMPEs weresubjected to adjustments, including some minor modifications and the calibration of the coefficients by using the indigenousdata. Then, a number of statistical and visual procedures were applied including the performance test of the adjusted GMPEswith the records of the two largest earthquakes that occurred in the region. The study highlights the influence of the localseismic behavior on the performance of various functional forms of the candidate GMPEs.
