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-vvave velocity to 30 in (V-s,V-30) and to other depths (V-s,V-z). Values for V-s,V-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,V-30 as well as V-s,V-z. The comparison showed that the WAVe method yielded similar V-s, profiles and V-s,V-30 leading to same ground type for seismic design.
