Abstract: Base isolation (BI) is one of the most widely accepted techniques of structural control to protect structures from strong earthquakes. It is introduced to decouple the building structure from potentially damaging earthquake motion preventing the superstructure absorbing the earthquake energy. In this project, base isolation systems are reviewed and their history, types, purposes and main principles are discussed. The research aims to study the effect of using base systems consisting of cross linear bearings and rubber bearings in improving the seismic behavior of tall buildings under the influence of several earthquakes, using the ABAQUS program, by changing several parameters (change of building height, friction coefficient within the cross linear bearing, damping energy of rubber isolators accompaniment).The mechanism of the base isolator increases the natural period of the overall structure, and decreases its acceleration response to seismic motion.
