Abstract

Maintaining various city functions during an earthquake is very important. However, the concrete earthquake measures method to preserve function of important facilities which constitute these city functions has not been advanced. We are focusing hospitals as the important facilities aiming to improve its seismic performance. Shaking tests for a full-scale four-story reinforced concrete specimen assuming a hospital including real medical facilities and equipment were conducted. The specimen was installed as a seismic-resistant or a seismic isolation structure on E-defense and shaken with short-period and long-period earthquake motion, respectively. The function in the seismic-resistant structure dropped significantly against the short-period earthquake motion. On the other hand, the seismic isolation structure exhibited immensely-high functional retention capacity against the short-period earthquake motion. But in the case of the long-period earthquake motion, serious damage in the function was confirmed.
