| Abstract: | Stay cables with various surface profiles were tested in wind tunnel.Dimples and helical fillets were applied to mitigate the rain-wind induced vibration.The rain-wind excited responses of the cable with smooth surface were larger than those of the cables with dimples and helical fillets.At high Reynolds number,the drag coefficients of cables with dimples and helical fillets are much larger than those of smooth surface cable. |
