Comparative Analysis of G+9 Building by Using Rubber Base And Friction Pendulum Systems in All Seismic Zones

Abstract

The base isolation procedure has been utilized to study the structures from the earthquake's harming impacts. Base isolation is achieved by installing isolators and energy absorbing devices under the superstructure, Seismic isolation provides not only structural safety, but also safety and security for people and properties in the building. Seismic isolation is also used for the retrofit of historic buildings. Seismic isolation and energy dissemination systems give an effective method of improving the seismic effectiveness of constructions through a typical seismic plan. Such strategies limit seismic loads by changing the inflexibility and damping of the constructions, though customary seismic design requires extra strength and flexibility to withstand seismic loads. Perhaps the main standards in the plan of tremor safe designs is the base detachment strategy. Seismic isolation systems can be modeled in various structural analysis programs using nonlinear or equivalent linear properties of isolators.In this present study a G+9 story building analyzed by using Rubber bearing isolation system and friction pendulum system in seismic all seismic zones namely zone II, Zone III, Zone IV and Zone V with the help of IS 1893:2016 Code in SAP 2000 Software package. The analysis is made between Rubber bearing isolation system, friction pendulum system and Fixed base building for seismic parameters like joint displacement , shear force, bending moment, building torsion, time period frequency etc. from the analytical results it was concluded that by using base isolation systems the values of base shear increased when we compared with fixed base building model. the storey shear values reduces to 35% in rubber isolation and 40% for friction pendulum models. The storey moment decreased to 25% in rubber base and 30% for friction pendulum model. The Optimum control of the parameters considered was observed when the building is damped with friction pendulum model in all the seismic zone conditions.
