Seismic isolation design isconsidered the most effectivedesign technology for protection measures against earthquakes as it is based on the concept of reducing the seismic forces transferred to a structure. With “seismic isolation design” it is now possible to seismically isolate not only new constructions but also existing constructions through the insertion of special devices between the base of the structure and its foundations There are lead core rubber bearings, high dumping rubber bearings and friction type bearings according to costumers needs. Lead Core Rubber Bearings; The lead cylinder facilitates very effective dumpingduring extreme movements. The dumping factor of lead core rubber bearings can be higher then 25%. High dumping rubber bearings; The high dumping rubber bearings HDRBconsist of multiple elastomer layers made of special dissipative rubber compounds,separated by reinforcing steel plates moulded to the rubber layer, and can be manufactured in a rectangular or circular shape according to customer requirements. Friction Type Seismic Isolator Bearings; This type seismic ısolators are dumping energy by friction of the materials. This bearings can divided into according their return system like curved (Pendulum type) or plate friction type (eradiquake type)
