공장과 사무실 바닥판의 진동 사용성 평가

Problem of structure vibration has recently become an issue. So the purpose of this study is to evaluate floor vibration for factory and office using acceleration data. In order to apply foreign vibration criteria, natural frequency, acceleration response were measured for walking load and ambient vibration. Case of factory structure, natural frequency are extracted numerical analysis and field experiment. With this information, a system identification has been performed to produce a numerical model representing existing floor. The peak magnitudes of acceleration for one man walking heel drop load from experiment and numerical model are analyzed using ISO vibration criteria and AIJ vibration performance criteria. Case of office structure, natural frequency are extracted field experiment. And acceleration responses were measured for one man walking heel drop, four men walking heel drop, and ambient vibration at afternoon and night. The peak magnitudes of accelerations were analyzed using ANSI architectural vibration criteria and AIJ vibration performance criteria.
