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.
