Seismic Risk Assessment of Lifeline Considering Hospital

Under destructive earthquakes, a medical sector should play a crucial role for taking care ofinjured people. Hospital building should also maintain their function. By the way, since ahospital has a system like a city, composing of buildings and many lifeline systems, seismicreliability of the hospital is not determined only by building but by lifeline facilitiesincluding inside and outside the hospital. Present paper proposes a seismic risk assessmentmethod for hospital lifeline as a part of the Seismic Risk Management method. Theassessment method is to evaluate availability of hospital systems, considering damageprobability of building and lifeline facilities, and the loss related to pipeline damage. Theproposed method is applied to ten hospitals in Osaka, and its applicability is discussed.
