在拉索上附加耗能减振阻尼器是斜拉索振动控制的主要手段之一，而拉索在附加非线性粘性阻尼器后的阻尼特性尚未见试验研究报道。

Dampers have been used for vibration mitigation of stay cables; however, there are few literatures on the test of full-scale stay cable attached with nonlinear viscous damper.

将所得变化规律与等效粘性阻尼理论相结合，给出了一种依赖于应变和频率的非线性阻尼本构关系式。

Based on above fitted relation and equivalent viscous damping theory, a nonlinear constitutive equation of damping alloy depending on strain amplitude and frequency is put forward.
