A stay cable with viscous damper and tuned mass damper
Australian Journal of Structural Engineering, 2015AbstractStay cables in cable-stayed bridges are vulnerable to dynamic excitation because their intrinsic damping is very low. The cables have often been exhibiting undesirable and excessive vibrations which result in increasing maintenance frequency and disruption to normal operations of the entire bridges.

Under near-field ground motions, fluid viscous dampers (FVDs) are effective in controlling deck longitudinal displacement but lead to the increase of bending moment and shear force at tower base.

Disclosed herein is a rotary viscous damper using a magnetic fluid as the damping medium. The damper comprises a permanent magnet rotor enclosed in a magnetically permeable housing. The magnetic fluid fills the space between the rotor and the housing and is held in place using magnetic forces generated by the magnet rotor.

In a viscous shear damper the seismic mass is chamfered at all its corners. Thus, the clearances between the seismic mass and its casing are gaps with oppositely widening out sections separated by middle sections of smallest widths.

Optimum design of viscous inerter damper targeting multi-mode vibration mitigation of stay cables
Engineering structures, 2021Installation of transverse dampers near the cable-deck anchorage is a commonly used method for the vibration mitigation of stay cables. Recent studies have demonstrated that the viscous inerter damper (VID) is an efficient scheme for controlling specific

In this paper, a new method is presented for designing nonlinear viscous dampers to improve the seismic response of multi-storey frames with braces. In this regard, a 2/3-scale three-storey steel structure is used as a benchmark case.
