Wind Tunnel Test and the Analysis of Buffeting Performance of Free-standing Tower of Cable-Stayed Bridge under Yaw Wind
The buffeting performance of free-standing tower of JiangHai Navigation Channel Bridge,a cable-stayed bridge,under yaw wind is investigated by means of wind tunnel test of aeroelasticmodel.It is found that the variation of buffeting response of free-standing tower with wind yaw angle is not monotonous.The lateral buffeting response on the top of the free-standing tower reach their minimal values and maximal values at around 150°and 180°of wind yaw angle respectively and the longitudinal buffeting response attain their maximal values at around 90°of wind yaw angle.Also,at the 2/3 height of the tower the lateral buffeting response and torsional buffeting response get their minimal values at around 150°of wind yaw angle,and at around 180°achieve the maximal values.It is also seen that,the buffeting response changes with the wind speed at a conic curve approximately.
