Abstract: Earthquake are one of the devastating natural calamities. Keeping in view of the varying effects of earthquake based on the nature of the location, IS 1893-2016 classified India into four zones namely Zone II, Zone III, Zone IV, Zone V. IS 1893-2016 has clearly stated that Equivalent static method can only be used for a regular building in Zone II whose height is within 15m, for all other structures Dynamic Analysis has to be used. The various Dynamic Analysis as per code are Response Spectrum, Time History and Modal Time History. A special method is developed by matching Time History function with Response Spectrum in both Frequency and Time Domain. The present work deals in analysing these methods in both Zone V and Zone IV when subjected with seismic excitations of Chamoli earthquake in Zone V and Uttarkashi Earthquake in Zone IV both of which occurred in year 1999 and both the earthquakes have same magnitude of 6.8 on Richter Scale. Parameters considered in the study are storey displacements, storey drifts, storey shears and base reactions. ETABS V.17.0.1 is used as the software tool for performing linear time history, response spectrum, matched time history and modal time history analysis of the regular structure.
Keywords: Chamoli Ground Motion Data, Linear Time History Analysis, Matched Time History, Response Spectrum.
