519 Full-scale Shaking Table Tests for Improvement of Functional Maintenance in Medical Facility against Earthquake

This research focuses on a hospital as one of the most critical facilities. The goal of this research is to improve seismic performance and function maintenance performance of the medical facilities and to ensure that the injured and wounded could be treated promptly after a major earthquake. Therefore shake table tests with the realistic hospital building specimen were conducted for the first time in the world. Some serious damages on the function occurred on the base-fixed structure against the large short-period ground motions and the seismic isolation structure against the long-period and the long-duration ground motions. The shake table tests on the medical facility prepared for the measures to prevent the damages were conducted again, and function maintenance performance of the medical facilities with the measures was verified. It was confirmed that the function of the medical facilities was maintained enough on the seismic isolation structure with the measures.
