In this paper, the field vibration measurement tests and analysis have been conducted for investigating the exact causes of the abnormal vibration accident which occurred on last July 5 2011 in TechnoMart. The vertical accelerations of the building floors were measured under the 4D movie-theatre operation and human rhythmic movements in a fitness centre which were estimated as ones of the vibration sources. From field tests, it could be identified that the building has global vertical vibration mode of 2.7Hz natural frequency and human group rhythmic movements having frequency component mainly close to 2.7Hz in a fitness centre caused the resonance of the vertical mode. The peak acceleration caused by the taebo was 7 which is slightly higher than the ISO 2631-2;1989 serviceability standards of an office building. |
