Outline of Final Research Achievements

Large span structures such as a gymnasium and an exhibition hall often use ceilings because of enhancing sound effects and reducing heating bills. The ceiling member fell down on a large scale due to the seismic motion according to the past great earthquake disaster reports. The purpose of this study is to investigate the vibration characteristics and propose the response performance evaluation method of the steel base conventional method ceiling in the school gymnasium based on the microtremor measurement and the time history analyses. The validity of the proposed practical method has been shown in comparison with the analyses.
