| Abstract: | Since 1973, the General Directorate of Disaster Affairs of Turkey has deployed several strong-motion accelerographs at selected
sites. Within the framework of the project entitled Compilation of National Strong Ground Motion Database in Accordance with International Standards, site conditions were investigated within the upper 30-m depth by surface seismic and standard penetration tests. Preliminary
characterization of the sites is made by making use of both geophysical and geotechnical criteria of NEHRP Provisions and
Eurocode-8 site classification systems. The liquefaction susceptibility of those sites which comprise saturated cohesionless
deposits is also determined. Mean shear-wave velocity, mean penetration resistance, site class, and liquefaction susceptibility
of each site are tabulated. The Turkish strong-motion database supplemented by detailed information on site conditions is
a valuable source of information particularly for those studies that put emphasis on the relationship between site conditions
and strong-motion parameters. |
