ANALYSIS OF LEAD RUBBER BASE ISOLATION AND FRICTION PENDULUM SYSTEM OF G+12 BUILDING USING ETABS SOFTWARE

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+12 storey building analyzed by using Rubber bearing isolation system and friction pendulum system in Zone V with the help of IS 1893:2016 Code in ETABS Software package. The comparison is made between Rubber bearing system and friction pendulum system with general building for seismic parameters like story drift, shear force, bending moment, building torsion, base shear, time period and frequency values are studied using Response spectrum analysis method.
