In this study, site conditions are derived for the Ankara Basin in Turkey by merging in-situ seismic measurements of dynamic properties, geologic information, and some geotechnical boring information. Field seismic surveys were performed at 259 sites in the project area to classify and characterize Plio-Pleistocene fluvial deposits and Quaternary alluvial and terrace deposits. The average shear wave velocities in the upper 30 m (Vs(30)) of the near-surface geologic units were used to characterize site classes according to the International Building Code (International Code Council, ICC 2006). The measured shear wave velocities of the near-surface geologic materials were utilized to develop a regional Vs(30) model for identifying local site conditions and for differentiating the characteristics of the geologic units in the western part of the Ankara basin. However, these data show that the geologic units cannot be directly assigned to site classes; hence, the distribution of shear wave velocity within a geologic unit may spread across multiple site classes, making site class determination based on geologic unit alone inaccurate.
