Abstract:

The vibration tests were performed for the stay cable damper systems with the high-damping shearing rubber dumper or the viscous shearing damper on the DASYLab5.0 software platform to analyze their damping properties. The results show that by installing the high-damping shearing rubber damper the stay cable damping is improved greatly, can meet the requirement of the cable to vibration mitigation, and the viscous shearing damper performs even better.

Key words: bridge engineering, stay cable, shearing damper, high-damping rubber, viscousity, vibration test
