RELATIONSHIP OF STRUCTURAL PROPERTIES AND ROOM DAMAGE RANK AT LOW- TO-MID-RISE MEDICAL FACILITIES

A room damage rank was built using shake table test results for assisting the seismic design of medical facilities with enhanced functional continuity. The proposed rank, categorized into four levels based on the communication with medical staffs, prognosis the medical service after seismic events using floor responses as engineering demand parameters (EDPs). To classify the rank, the maximum floor acceleration, maximum floor velocity, arias intensity and the integration of bracketed acceleration are considered as EDPs. The proposed rank was verified with past survey results. Then, the relationship between the structural properties and room damage were investigated by parametric analysis.
