Abstract: Earthquake is a natural and unpredictable calamity. It leads to loss of precious human life and property and at the same time pushes the national economy in the backward direction. As we know occurrence and magnitude of an earthquake are unpredictable. So, codes need regular updating to provide safety to the structures and human lives as well. These codal provisions are based on the return period of the earthquake and its magnitude. By employing these magnitudes into considerations, codal provisions have been revised regularly and has a different significance based on the earthquake zones. The prime objective of this investigation is to study the influence of seismic parameters if a building existing in zones with less seismic probability, experienced severe earthquake shakings and what should be the safety measures we need to provide for the safety of the structure and human life as well in such cases? To understand this, a G+6 storied reinforced concrete building is modelled using commercially available 3-Dimensional Structural Analysis and Design Software (STAAD.Pro) and then analysed for the different zones against earthquake forces. Seismic analysis has been done with dynamic linear analysis by using response spectrum analysis method by taking the significance of all the zones in India. Use of master-slave has shown the reduction in nodal displacements. Based on this study, it is concluded that analysis with master-slave results in economical design in comparison with design without considering master-slave.
