Abstract

Empirical correlations V^-N^ for soils of Greece: a comparative study of reliability G.A. Athanasopoulos Department of Civil Engineering, University ofPatras, Greece Abstract A review of available empirical correlations V^-Ng^ is presented. Two recently developed Greek correlations ("CLPW" and "Athanasopoulos") are further examined and their predictions are compared in terms of V,<, values as well as in terms of estimated ground response at several sites in Greece. It is found that the "Athanasopoulos" values of V,* exceed those of "CLPW" by 8.2% on the average. In terms of seismic ground response it is found that the peak ground accelerations, shear strains and shear stresses may deviate by ± 13%, ± 28% and ± 13% respectively when the "Athanasopoulos" values of V,<, are used vs. the "CLPW" values. The deviations of spectral accelerations ranged from - 20% to 4- 9%. It is concluded that these deviations are much lower than the deviations of "Atha
