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.
