Supporting cable trays in high-vibration environments requires more than just “stronger” steel. It requires a system-wide approach involving locking fasteners, specialized damping materials, and tighter support spacing. For steel structures, a dimensionless damping coefficient of 1% of the critical damping is widely accepted; however, for structures consisting of several materials, damping coefficients may be higher and estimating them reliably is very important. This paper studies the case of damping. efore, it is important to understand the effect of the bushings on the performance of the external damper. Besides, for long cables, external dampers installed at a single position near a able end can no longer provide enough damping due to the sag effect and the limited installation distance It. Cables are widely utilized as load-carrying members due to their excellent mechanical properties. MAURER cable dampers are available in passive and semi-active versions.
