| Abstrait: |
In general, temporary tied-down cables are used on cable stayed bridges during construction for stabilization when subjected to wind loads. However, the system requires temporary concrete blocks or pile foundation. Thus, tied-down cable systems are an expensive temporary method and have the potential of causing environment pollution problems; furthermore, the system may interrupt the route of ships or induce collisions. Tuned mass damper (TMD) system is proposed to cable stayed bridges or similar structures to supress wind-induced vibrations and ensure aerodynamic stability. TMD systems are more economical and workable in comparison with the temporary tied-down cables. TMD is shown to be the most efficient solution to bridge stabilization during construction when subjected to wind loads. |
