<p>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.</p><p>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.</p>

<p>In general, the stabilizing measures by temporary tied-down cables during typhoon are used to the free cantilever construction for a cable stayed bridge. However, it needs temporary concrete blocks or pile foundations to rest on 30m deep sea in the Busan~Goeje fixed link (BGFL) site. Thus it is a very expensive temporary method and could cause an environmental pollution problem to dredge the ground in the sea. Moreover, it could disturb the route of the ships or induce ship collisions.</p><p>A TMD (Tuned Mass Damper) is proposed to the three-pylon cable stayed bridge during construction to suppress the wind-induced vibrations and ensure the aerodynamic stability.
