Now a days architects and engineers are required to plan and design the structures , which can withstand
against the seismic loads. Therefore it became necessity to provide passive control device “base isolation” to resist large
horizontal and vertical load which leads the structure to collapse.Base isolation is one of the promising and widely
accepted passive control device to resist these forces by isolating the super structure from the sub structure, in this
research paper the response of Base isolated building and fixed base building are evaluated for high rise building having
irregularity in plan at Storey level. Response spectrum analysis and time history analysis carried out in terms of Storey
Displacement, Base shear, Time period and Storey drift using ETABS software.
