Earthquake Analysis of G+10 Building using Response Spectrum Method and Time History Method - A Comparison

Prakriti Chandrakar, Dr. P. S. Bokare

Abstract: Earthquake occurred in recent past have indicated that if structure are not properly designed and constructed may causes great damage to the structures. Hence we will have to confirm safety against the dynamic force like earthquake force that are affecting the structures, and determine seismic responses of such building. Time history analysis is significant technique for structural seismic analysis particularly when evaluated structural response is nonlinear. In present work an attempt has been made to study the dynamic behavior of G+10 multistoried building frame for two distinct plan geometries one bisymmetric regular rectangular frame and another frame with T shaped plan using IS1893-2002 recommended response spectrum method and time history analysis. In time history analysis, two earthquake data from previous earthquakes corresponding to (Nepal 2015) and (EL Centro 1940) is taken. Study focuses to evaluate two important parameters which are (a) Base shear and (b) maximum deflection. Analysis has been carried out using ETABS software. Based on result it is found that the base shear obtain from RSM is slightly higher compared to THM, and also storey deflection is more in response spectrum method than time history method.
