1·Put forward a new method for long-span bridge buffeting analysis which using quasi-steady aerodynamic stiffness and unsteady aerodynamic damping based directly on wind tunnel test.

提出采用准定常气动刚度与基于试验的非定常气动阻尼进行气动修正的大跨度桥梁抖振计算新模型。

2·Stable periodic motions such as wing-rock and oscillatory spin tend to be suppressed or the amplitudes be lessened due to the rotational damping of the unsteady aerodynamic delay.

对于稳定的周期运动，由于增加了系统的阻尼耗散项从而减少了振荡幅度。
