Özet

The Disaster and Emergency Management Authority of Turkey is currently operating 850 strong-motion stations throughout the country. At 112 of 850 station sites, variation of shear-wave velocity (VS) with depth was measured by the multi-channel analysis of surface waves (MASW) technique and also by the refraction microtremor (REMI) technique at another 256 station sites. For these 368 station sites, measured VS profiles are grouped into five different site categories according to their corresponding VS30 values, time-averaged shear-wave velocity over the top 30 m of the site profile. Parametric models for the median VS profiles are proposed. Median, Median ± standard deviation VS-depth trends derived for Turkey are critically compared with those obtained for California, Japan, and Taiwan by Kamai et al. [1].
