A new type of viscous shear damper for cable stayed cables is introduced, and the design principle and method of the damper are given. The dynamic test method was used to study the vibration reduction performance and damping of the bridge in laboratory and in real bridge. The test results were also analyzed. The research shows that this kind of damper has excellent damping performance and can be completely used for the vibration control of the real bridge cable.
