동조액체댐퍼를 이용한 고층건물의 공력진동모형실험

다국어 초록 (Multilingual Abstract)

Many investigations for reducing wind-induced vibrations of tall building have been conducted. One of them is adding an auxilIary damping device to the building so increase damping ratio of building and reducing responses of the building. In this paper, a passive TLD attached on the top of the aeroelastic building model of which has different side ratio of 2 and 3 and of which aspect raio is 8, was used for wind tunnel test. The boundary layer flow representing suburban area was simulated with normal direction is normal to the small face of the building model. The rms across-wind displacements at the top of the building model which was caused mainly by vortex-induced excitation were measured. It was found out that the effect of vortex-induced excitations of tall building is reduced effect of vortex-induced excitations of tall building 15 TLDs which have mass ratio of 1%-2% and frequency ratio of 0 95-1 05 were used for test. From the test results, maximum TLD effects for reducing vortex-induced excitations appears at the mass ratio of 15% and frequency ratio of 1%.
