The extent of an earthquake destruction varies from location to location because it is influenced by the local site impacts and the nature of the bedrock motion. The behavior of the soil beneath a structure during the propagation of earthquake waves determines the safety of the building at any location. When it comes to the ground surface, the amplitude, frequency, and duration of seismic motion at the bedrock changes owing to the topography of the site and the soil geomorphology. To determine the impact of local site conditions, borehole data from Sri Damodaram Sanjeevaiah Thermal Power Plant at Nellore is collected and one-dimensional ground response analysis is performed using both equivalent-linear and non-linear analysis using DEEPSOIL. SPT “N” value is used to correlate shear wave velocity. In this study, the amplitude content and frequency content of the Chi-Chi motion, Loma-Gilroy motion, and Kobe motion are taken into consideration. Peak surface acceleration and design response spectra are used to compare and illustrate the results of the two analyses.
