능동질량형 제진장치의 제진성능 평가에 관한 연구

Abstract

This paper presents an application of the active mass damper (AMD) system to a high-rise building structure. The building has five basement floors with SRC structural system and 26 floors with steel structure system, and which makes inherent low damping ratio. To figure out the reason of the occupants’ discomfort, the preliminary field measurement was performed and additionally the wind tunnel test was carried out. The AMD system was selected to reduce the wind-induced vibration so that the serviceability of the building is assured. It is the first application of AMD for residential building in the country. Usually, the vibration control devices have been planned and implemented during construction stage. On the other hand, in this project the AMD system was implemented to the building in-use and this may be the first full-scale application of AMD to the existing building in the world. The two AMDs were implemented in June 2007 and the performance tests were also carried out. This paper mainly focuses on the performance test under the strong winds due to typhoon NARI in 2007.
