| Abstract: |
The TMD (Tuned Mass Damper) method of construction is proposed to the cable stayed bridge or the similar structure to suppress the wind-induced vibrations and ensure the aerodynamic stability. This stabilizing method of construction by TMD does not need any foundations. Thus it could solve the environmentally constrained problems by excavation or dredge of the ground and the risk of the traffic collisions. Moreover, it is more economical and workable in comparison with the temporary tied-down cables. It is shown that the vibration control by TMD is the most efficient solution to stabilize the bridge during construction regarding wind. The three-pylon cable stayed bridge at the Busan~Geoje Fixed Link in the south-eastern part of Korea is introduced to show the example for the application of the TMD method of construction to solve the environmentally constrained problems. |
