NON - LINEAR ANALYSIS OF MULTISTOREY G + 4 BUILDING BY TIME HISTORY METHOD USING NEWMARK’S LINEAR AND AVERAGE ACCELERATION METHOD

His paper presents the non linear dynamic analysis of G + 4 store y building using Newmark’s time stepping methods. The ground acceleration data used for this study was EL Centro values. A total of 1559 ground acceleration values are considered for calculation of peak lateral force, shear force, displacement for each flo or and these results are compared with static analysis of the same considered building as per IS 1893(PART I) ; 2002. Results showed that the there is a need for improvement in analysis of ground soft storey structures where the buildings week and tend to critical effect due to earthquake effect.
