Abstract

In the present study, acceleration design-response spectra (ADRS) for deep and shallow sites have been proposed for different seismic site classification as per NEHRP. Nonlinear site response analysis has been performed at different subsurface profiles and surface spectra have been derived. The site factors in terms of short period or 0.2 s (Fa) and long period or 1.0 s (Fv) for both the regions has been estimated. Finally, using these site factors, ADRS for both the regions have been proposed. This is the first time such extensive study has been done for developing the ADRS for the deep and shallow sites of India or Asia for different seismic site class.
