Seismic Analysis of Multi-Storey RCC Building by Various Static and Dynamic Analysis Methods

From past earthquakes it is observed that if the structures are not properly analyzed and constructed with required quality, then it may lead great destruction and loss to human lives. It has been proved that many of structures are fully or partially damaged due to earthquake. This fact was never ignored while design of multistoried buildings by the structural engineers, researchers to ensure safety against earthquake forces while erection. So, there is need to determine seismic responses of such buildings. Seismic analysis of the structure is carried out for determination of seismic responses by time history analysis which is one of the important techniques for structural seismic analysis especially when the evaluated structural response is non- linear in nature. To perform such an analysis, a representative earthquake time history is required for the structure being evaluated. In this present work non-linear dynamic analysis of G+10 storied RCC building having mass irregularity considering different time histories is carried out. Here a G+10 stories building with mass irregularity has been modeled for seismic analysis and Elcentro earthquake time history and Kobe earthquake time history have been used. This paper highlights the effects on floor which has different loads (mass irregularity) in multistoried building with time history analysis by ETABS 2016 software.
