heal.abstract	Empirical predictions of soil effects on seismic ground shaking are related to 1-D seismic response analyses. The comparison focuses upon the peak ground acceleration (amax) and velocity (Vmax), the elastic acceleration response spectra (Sa) and the average horizontal Fourier amplitudes over a short and an intermediate period band (AHFA, AHFA). Empirical predictions in terms of site geology are within the overall range of analytical predictions for amax and Vmax, but they do not depict the detailed effects of seismic motion and site characteristics. In addition, they agree to analytical predictions of Sa for relatively deep and flexible sites, but differ significantly for other sites. Empirical predictions in terms of the average shear wave velocity, agree well with analytical predictions for amax, Vmax, AHFA and AHFA in the case of shallow and stiff sites subjected to weak seismic excitations, but they are relatively higher in the opposite case. Empirical predictions of Sa are generally within the range of analytical predictions, although empirically predicted peak amplification can not be related to resonance between the soil and the superstructure.	en
