Abstract
Abstract: The study of multi-story building behaviour always depends on strength, durability, stiffness and adequacy of the regular configuration of the structures. Understanding the seismic behaviour of asymmetric structures is a challenging task, considering the aspect of irregularity (either in the plan or elevation) is generally known as asymmetric. Various researchers had studied the behaviour of this asymmetrical building by taking into considerations of different approaches such as plan configuration, vertical irregularity, mass and stiffness, in different methods of analysis. The irregular structures are less prone to the seismic forces, hence there is a need to study and specify some improvements in codal provisions for this type of asymmetrical structures. In the present study, we have considered a plan irregular structure (which replicates the Microsoft building at Hyderabad). The overall structural behaviour of asymmetrical building is investigated under different earthquake cases, such as with El-Centro, Loma and Uttarkashi database. Analysis of structure (using software program E-TABS V-17) for various earthquake intensities and checking for multiple criteria at every level for essential practice. The non-linear methods Time History analysis is carried over to find the structural behaviour. Keywords: multi-story building, plan irregularity, Time history analysis
