| Research Abstract |
The purpose of this study is to estimate the performance of healthcare facilities following an earthquake. Healthcare facilities such as hospitals carry great importance principally following a disaster. The function of hospitals after an earthquake depends on many factors such as structural damage, lifeline damage, lack of stag lack of medicine and others. Questionnaire survey was conducted for the hospitals suffering damage due to the 2007 Noto-hanto and the 2007 Niigata-ken Chuetsu-oki Earthquakes. The damages to each component such as structures, lifelines, instruments and so on in the hospital were investigated. The relation between strong motion and damage to each component was also studies.
Next, a shaking table test and simulation of three types of equipment, that is, a wheeled table, shelves and small equipment which can be medicine container, were conducted. The results showed that the more the shelf is attached to the structure the more stable it becomes. The most unstable types of shelves are those which are connected only by their bottoms. Simulation and experimental determination response of wheeled equipment was finalized. The wheels are equipped with brakes and this causes a difference in response according to the brakes being in a locked or unlocked position ; rocking or sliding respectively. An unlocked setting was found to be stable while the locked setting was unstable. Low frequencies seem to make the equipment unstable while high frequencies seem to stabilize it.
Finally, the fragility of some system was studied. The fragility of equipment depends on the frequency. Low frequencies tend to make the highest damage to systems and therefore to healthcare facilities. Hospitals subjected to long period motion of a great scale earthquake suffer severe damage to their unconnected equipment.
