Turbulence Effects in the Full Bridge Aeroelastic Model Tests for the Hong Kong Stonecutters Bridge

MEL Consultants Pty Ltd has carried out the full bridge aeroelastic model tests in the large wind tunnel at Monash University for the Stonecutters Bridge for the Highways Department of the Government of the Hong Kong Special Administrative Region, China. The 1/200 scale model measurements have shown that the vertical dynamic response of the deck is very sensitive to turbulence intensity. From measurements for the critical direction with wind normal to the bridge deck with approach wind flows of turbulence intensity of 0.17, 0.13 and 0.11 at deck level, namely from hilly terrain, sea terrain and smooth terrain respectively, the vertical response of the centre of the span is shown to vary with turbulence intensity to approximately the power of 2.3 which highlights the importance of turbulence factors in both wind tunnel studies and analytical methods in predicting the full scale bridge response due to wind action.http://apcwe-vi.kaist.ac.kr/listofpapers.pd
