The importance of the effect of sediments above bedrock in modifying the strong ground motion has been long recognized. To account for this, some codes of practices incorporate individual response spectra for different types of soil. As an improvement over this the amplification factors derived out of empirical and theoretical data are suggested in some of the international seismic codes for different site classes. In these codes, site-specific analysis is recommended for soft soil type (site class F). In this paper, the importance of the site-specific response for three actual sites of Delhi for medium soil sites has been investigated. For these studies scenario earthquakes from Himalayan region reported in literature have been chosen. It has been demonstrated that for Delhi region it may be necessary to perform the site-specific analyses of buildings at sites having medium types of soil as well.
