Earthquake geotechnical engineering is the branch of engineering that deals with the effect of soil properties on different ground motion parameters due to the seismic forces generated inside earth’s crust. It has been observed by various researchers that the level of ground shaking on earth’s surface lying on soft soil is much more than the hard rocky surface which forms the basis to go through the soil properties beneath the earth’s surface for better prediction of ground motion during earthquakes to design more safe earthquake prone structures. According to IS:1893 published by Bureau of Indian Standards, Ludhiana City of Punjab, situated in Northern part of India, comes under Zone IV having value of peak ground acceleration as 0.24 g at rocky surface. But the actual ground surface acceleration is affected by the type of underlying soil at different regions for which one-dimensional equivalent linear ground response analysis of three different sites in Ludhiana LDN1, LDN2, and LDN3, namely Punjab Mata Nagar, Pokhwal Road; Sunil Park, Barewal Awana and Kangawal, Post Jugiana, respectively, was carried out considering Hard Bed Rock model using DEEPSOILv6.1 software under the earthquake motions of Loma Gilroy Earthquake (PGA 0.17 g), Uttarkashi Earthquake (PGA 0.24 g) and Artificial Earthquake Motion generated by SeismoArtif software (PGA 0.392 g). All the sites under consideration fall under category ‘D’ as per NEHRP. The maximum surface peak ground acceleration was observed to vary from 0.3979 g to 0.8136 g, Amplification ratio from 1.999 to 2.502 and peak response spectral acceleration from 2.0203 g to 3.4516 g.
