Evaluation of Displacement and Storey Drift for Multistoried Building Using Time History Analysis

An earthquake may cause great destruction to the structures if they are not properly designed and constructed. This has been observed in the past earthquakes. Consequently, we should affirm well-being of the structure against the seismic tremor by carrying out dynamic analysis to determine seismic response of the structure. Dynamic analysis of a structure can be done by two methods—one is response spectrum method, and second is time history method. When the evaluated structural response is nonlinear, the time history method becomes an important technique for seismic analysis of the structure. In this paper, we used time history method for dynamic analysis of the structure. A G+5 multistoried building is modelled in STAAD PRO software, and the dynamic response of multistoried building such as displacement and storey drift is evaluated using two ground motion data, namely 2001 Bhuj and 1999 Chamoli earthquakes of India. In the results, displacement and storey drift are compared for two ground motion. It can be observed from the analysis that the displacement and storey drift of multistoried building for Chamoli earthquake ground motion are greater than around 19% than that for Bhuj earthquake ground motion.
