Analysis of G+10 Storey Building with Rubber Bearing Isolation System and Friction Pendulum System in Seismic Zones

Abstract

The process of base isolation has been applied to investigate the structures that were damaged by the earthquake. Base isolation is accomplished by putting in isolators and energy-absorbing equipment beneath the superstructure. Seismic isolation offers people and property inside the building safety and security in addition to structural safety. Historic building retrofitting also makes use of seismic isolation. By using a typical seismic plan, seismic isolation and energy distribution systems provide an efficient way to increase the seismic efficacy of projects. Although standard seismic design calls for more strength and flexibility to handle seismic stresses, these tactics limit improvements to the inflexibility and damping of the constructions.

With the use of ETABS, a G+10 storey building equipped with a friction pendulum system and rubber bearing isolation system is examined in all seismic zones in the current study. The analysis of seismic parameters such as joint displacement, shear force, bending moment, building torsion, time period frequency, etc. is done between Rubber bearing isolation system, friction pendulum system, and fixed base building. The analytical results showed that, in comparison to fixed base building models, the values of base shear increased with the use of base isolation systems. In all seismic zone conditions, the building that is damped using a friction pendulum model has the best control over these parameters.
