Abstract
Earthquake is a natural disaster which can cause severe damage to human lives and properties. Recent earthquakes which occurred during last decade have indicated that major damage occurred was not directly due to actions of earthquakes but due to poor performance of structure during earthquake. It is said that the earthquake will not kill the human life, But the structures which are constructed by not considering the earthquake forces do. There are many methods to reduce the damage caused by the earthquake. The most advanced methods are Base isolation and Energy dissipation devices. Energy dissipation devices is also known as dampers. There are many types of dampers such as viscoelastic dampers, friction dampers, tuned mass damper, fluid viscous damper, magnetic damper, yielding damper etc., Among all dampers fluid viscous dampers has been used in various structural and mechanical systems. The main objective of the study is to model and analyze the structure against the seismic loads. In this study, fluid viscous dampers are used in the G+5 L-shaped framed structure and the seismic analysis is carried out by using ETABS (version 19) software. The data required are taken from IS1893 2016 code. The method used for seismic analysis is Response spectrum method. The structure is assumed to be in zone II. The response of the structure before and after the application of the dampers is studied. The results are discussed based on parameters such as maximum storey displacement, maximum storey drift, storey stiffness, overturning moment, storey shear.
