Stay cables are susceptible to vibration under wind and traffic loading due to their large flexibility, relatively small mass and very low inherentdamping.
由于拉索具有极大的柔性，相对较小的质量，以及非常低的阻尼，其对风荷载及交通荷载引起的振动十分敏感。

The damping in a viscous damper is the same as the inherentdamping that is assumed as viscous damping, which is likely to make it easier and exacter analyzing a structure with added viscous dampers.
由于所附加的阻尼和传统结构分析中所假定的粘滞阻尼一致，这使得减震结构的分析有可能比较方便、精确。

This method possesses the desirable properties of high accuracy, inherent numerical stability (no wiggles), non numerical damping and algorithm simplicity.
