COMPARISION OF BUILDING FOR SESMIC RESPONSE BY USING BASE ISOLATION

Abstract

Throughout historic time Earthquakes are one of the natural hazards that occur due to sudden violent movement of earth's surface which causes damage to property, especially to man-made structures. Base isolation is one of the most powerful tools of earthquake engineering pertaining to the passive structural vibration control technologies. The application of the base isolation techniques to protect structures against damage from earthquake attacks has been considered as one of the most effective approaches and has gained increasing acceptance during the last two decades. This paper present three dimensional nonlinear time history analysis is performed on r/c building by the use of computer program SAP 2000 v12.0.0. The dynamic analysis of the structure has been carried out and the performance of the building with and without isolator is studied. The main objective here is to make seismic response control by providing Isolators and comparing between the fixed based and isolated base building. Rubber bearing and Friction pendulum bearing are used
