Measurement of earthquake excitation through sub-surficial soil layers to site of interest have a prominent role in any structural design. Ground response analysis (GRA) has been carried out to check the effect of earthquake on local soil condition adopting equivalent linear method. Response spectrum is generated using DEEPSOIL for the 16 borehole locations of Jalandhar, Punjab using geotechnical data. Bedrock motion used for this analysis is taken from Jalandhar station. The shear wave velocity is determined empirically by the correlation between standard penetration test value (SPT-N) and shear wave velocity. Average shear wave velocity at 30 m depth is determined and, further 16 borehole sites are classified using NEHRP guidelines. The response spectra are plotted with IS code response spectra and, further the responses are used for determination of the base shear of the building. As per this study, site-specific response spectra is higher for lesser time period, whereas IS code 1893 (Part 1) 2002 response spectra is higher for higher time period. The building used for analysis is already constructed having an orientation of 39° with the north direction. The analysis of the base shear is carried out using STAAD Pro. The base shear results are interpreted by using the different modes of combination and the results are compared between site specific response spectra and IS code response spectra. The average of difference in percentage for SRSS, 10PCT, ABS, CQC is −2.93, 1.24, 0.98, −3.16 respectively.
