This paper studies the case of damping estimates for steel trays supporting cable bundles. Free vibration signals were experimentally acquired using a steel beam with and without attached cables,
However, the inherent damping of cables is usually extremely low, thereby causing undesired vibrations to occur frequently under various external
Compared with typical seismic resistant elements such as the steel brace, diagonal- and chevron-brace damper, the proposed optimal TBD can dissipate more energy and effectively
It is thus of interest to improve cable damping by additionally installing dampers inside the guide pipe. This paper hence studies the combined

The negative stiffness damper (NSD) has emerged as a promising passive vibration control device for cable structures due to its simplicity and effectiveness. However, uncertainties
The research on the cable-damper system can be traced back to the 1980s. Carne (1981) and Kovacs (1982) were among the first researchers to investigate the vibrations of a taut cable with...
The cable tray system, one type of non-structural components, may suffer severe damage and even fall in case of earthquakes, causing interruptions to post-earthquake operations and even
