| Abstrait: |
The new device works like an impact damper, embedded inside the stay-cable in order to decrease the dynamic “hazards” in various cable eigenmodes. Vienna University of Technology has developed a method to increase the structural damping of stay cables. Advantages in regard to conventional dampers are the simple and robust technology and the fact that all components required for the new method are located inside the structural components (cables). In full scale field tests on stay cables with a length of 31,2 m the damping ratio of a conventional stay cable and a stay cable equipped with the damping system could be compared. |
