Current thinking

摘要

In 1940, the Tacoma Narrows Bridge in Washington State collapsed due to the effects of Vortex Induced Vibration (VTV), where vortices are formed and shed on the downstream side of bluff bodies or rounded objects in a fluid current.rnThe vortex shedding alternated from one side of the bridge to the other, creating a pressure imbalance that resulted in an oscillatory lift, leading to the total destruction of the bridge.
