A parametric study was performed on 19 hypothetical shallow profiles each shaken by 74 records using equivalent-linear method. The results were analyzed to identify trends. Site period migration due to nonlinear behavior has a critical role on site response. Amplification versus shaking intensity models was compared. Depth-dependent models were found more suitable than depth-independent models. Strain compatible site period was found a promising site parameter that complements the predictive information obtained from VS. A procedure providing a five-point estimate of site transfer function is outlined.
