Abstract :Most of our country is located in the earthquake zone where active fault lines exist. Statistical analysis show that damaging earthquake occurs every 8 months in our country.The major devastations due to the 1999 Kocaeli and Düzce earthquakes have caused almost impossible losses to compensate for the country`s economy. The health facilities damaged or destroyed in these earthquakes caused the disruption of the most needed health services after the earthquake, and hence increase of the losses. Seismic isolation can be defined as, considering the characteristics of earthquake acceleration, preventing damage to small or medium-sized earthquakes, and reducing the damage to large earthquakes by increasing the period and damping of the building. Seismic isolation is an earthquake-resistant structural design approach based on the principle of reducing the seismic force of the buildings by extending the period of the building, rather than increasing the seismic resistance capacity of the structure. The right applications of this technology allow buildings to be elastic even during major earthquakes.
