Abstract

The weighted average velocity (WAVe) method was recently proposed as an alternative inversion algorithm for obtaining shear-wave velocity (V_s) profiles from Rayleigh wave dispersion curves. In this paper, the WAVe method is discussed in relation to its accuracy in estimating the average shear-wave velocity to 30 m (V_s,30) and to other depths (V_s,z). Values for V_s,30 are used in building codes to determine ground-type classes for seismic design. Five case studies, representing typical shear-wave velocity (V_s) profiles, are presented. The V_s profiles obtained using the WAVe method and those obtained using more rigorous inversion methods were quantitatively compared based on V_s,30 as well as V_{s, z}. The comparison showed that the WAVe method yielded similar V_s profiles and V_s,30 leading to same ground type for seismic design.
