In general, large-span cable-stayed and suspension bridges require bridge towers with a length of more than tens or hundreds of meters. Due to the unproportionate slenderness ratio, the bridge tower becomes vulnerable to air and thus easy to be distorted or to vibrate, which will affect the stability of the entire bridge structure. Therefore, it is of great significance to carry out an in-depth research on the force feature of the bridge tower in a flow field.
