Abstract
The concept of base isolation systems has gained wide spread acceptance in enhancing the earthquake resistance of a structure. To accomplish the predicted behaviour of the base-isolated buildings, the design for base isolation system is regarded as the dominant factor. The base isolation of the structure basically reduces the storey shear and acceleration and increases time period, storey displacement and storey drift inducing flexibility in rigid structure by dissipating energy to foundation. For the study, three framed structures in zone-V with vertical and horizontal irregularity having G+10 storey have been analysed for its seismic behaviour with and without isolator using ANSYS. The analysis incorporating earthquake load is based on the seismic coefficient method as described in IS 1893: 2002. The study has been conducted in complete conformity with various provisions in Indian Standards as Code of Practice for plain and reinforced concrete IS 456-2000 [1].
