| Abstract |
Modern flexible tall buildings with reduced damping ratios are sensitive to wind-induced vibrations. Most of the excessive wind- induced vibrations of tall building are due to vortex-induced vibrations. The type of building section model having sectional area of 0.0025㎡ and the height of 0.5m with side ratio denoted as D/B, of 1.0, 2.0, 3.0, 4.0 was selected for aeroelastic experimental study. All measurements were made in a boundary layer wind tunnel at the Chonbuk National University Wind- tunnel Lab.??In this paper, the vortex induced vibration of tall buildings with aspect ratio 10 with side ratios 1,2,3,4 is investigated in turbulent layer flows over??suburban areas.??Effectiveness of increasing damping ratios was investigated. |
