변풍 풍하중에 의한 고층건물의 동적응답에 관한 연구

In order to investigate the torsional vibration of aeroelastic model to wind load, square section of aeroelastic model with aspect ratio, H/BD of 10 and side ratio, B/D of 1:1 ,were used in the test. The wind tunnel test was carried out in turbulent boundary layer flow over suburban area. Torsional vibration phenomenon and coupled vibration was observed, which might be considered as aeroelastic instability phenomenon.
