Due to the variety in the categorization of nonstructural components and medical equipment in a hospital, before embarking on seismic design, the critical and/or vulnerable nonstructural items should be identified and prioritized. In this study, consulting with the constructors and hospital facility managers, the procedures and accompanied tools including the screening criteria, simplified seismic evaluation form, design equirements and appropriate seismic restraints are proposed and recommended for the nonstructural components and equipment in a hospital. Furthermore, some critical and vulnerable medical equipment items were chosen for shaking table tests to verify the application of proposed simplified evaluation forms and recommended seismic restraints. Based on the modeled specimens of medical equipment, the test results revealed that restraint devices actually contribute to decrease displacement response, but it increases acceleration response of the equipment due to the impact effect. Besides, damages of adhesive layer between restraint devices and equipment or anchors at partition wall appeared under larger earthquakes. Based on the test results, the simplified evaluation form and seismic restraints were modified to be applicable for free-standing medical equipment, and further, the pull-out strength of partition wall and the adhesive strength of non-destructive devices were taken for the next research subjects for seismic design of medical equipment. |
