COMPARATIVE STUDY OF MULTI-STOREY RC BUILDING WITH AND WITHOUT BASE-ISOLATION

Kothireddy Akhil Reddy, Dr J S R Prasad, Dr. Venu Malagavalli.


Abstract

Development in the design of earthquake resistant buildings has been growing since about 100 years ago. In the design of earthquake resistant buildings, the main aspects to consider are life safety and damage reduction on architectural element caused by the earthquake. However, with the development of age, modern buildings contain sensitive and expensive equipment that become vital for business, commercial, education and healthcare. Hence, the equipment inside the building needs to be protected when the earthquake occurs. The basic principle of base isolation system is to provide flexibility in the building and at the same time provide damping to prevent amplification caused by the earthquake. By placing structure on the base isolation system, it will prevent horizontal movement of the ground transferred to the structure and produce a significant reduction in the acceleration of the earthquake.
In the present study analysis of G+3 building analysis is carried out by using base isolation system rubber base system. The results like storey drift, storey shear, storey bending, time period, model frequency is analyzed by using Response spectrum analysis.

Key words: Rubber base, friction pendulum, storey drift, storey shear, storey bending, time period, model frequency.
