Abstract
In the present study, new elastic design response spectra (EDRS) for the deep and shallow region of the Indian subcontinent has been proposed for rock and soil site. For determining the EDRS for bedrock, 50 each rock recorded ground motions have been used for Intra and Interplate region. For determining the EDRS for soil sites, 250 and 178 ground motion for deep and shallow sites has been used, respectively. For SI, only few ground motions are available, hence for developing EDRS for shallow sites, ground motions recorded at similar tectonics have been used in the present study. Further, EDRS is derived based on Eurocode, i.e. normalized elastic design response spectra which is based on one parameter, i.e. effective ground acceleration at rock.
