Analysis of RC Building Using Base Isolation and TM Damper System.

Abstract

Used to protect the structures from the damaging effects of earthquake the installation of base isolators at the base increases the flexibility of the building structures and TM dampers reduce structural integrity with possibilities of failure. In this study reinforce concrete structures are taken for seismic performance evaluation. This RC building is modelled with different structural control system such as High Density Rubber Bearings, Friction Pendulum System and Tuned Mass Damper with use of commercial computer software ETAB. After that various ground motion data is applied to the building model to evaluate structural response. Nonlinear time history analysis is carried out for building model with each control system and the result of seismic response of each compared with other control system. The results obtained from analysis were base shear and Storey drift it is greatly reducing by use of FPS over HDRB and TMD. Also concluded that FPS gives maximum base displacement compared to HDRB and TMD.
