Abstract
Site amplification coefficients and acceleration design response spectra (ADRS) for the shallow sites in SI are derived based on non-linear site response analysis at 125 locations. Input motions are selected by considering the seismic hazard map for 475 years as return period and inputted at depth where VS ≥ 1,500 m/s. The new site factors, i.e. FPGA, Fa, and Fv, are proposed for Southern India (SI) by classifying the sites seismically considering National Earthquake Hazards Reduction Program (NEHRP). Using the calculated site factor, a new ADRS is developed for SI, which depends on peak ground acceleration and seismic site class. The compatibility of ADRS is further evaluated with NEHRP and BIS:1893.
