Reasons of the Failure of Tacoma Narrows Bridge

Paper: In order to prevent the collapse of the Tacoma Strait Bridge, all static and dynamic strains need to be considered These distortions will take into account the environmental conditions, building materials and design. I. Environmental condition A. Influence and behavior of moderate wind to the bridge, wind of large vibration wind Wind turbulence vortex street vortex crushing frequency II. Construction material A. Material properties

Tacama Channel Bridge was the first Tacoma Channel Bridge in 1940. This is a suspension bridge across the Tacoma Strait of Puget Sound between Washington State and Tacoma and Kissap Peninsula. It opened on 1 July 1940 and became Puget Sound on 7 November the same year. At the time of construction (and its destruction), this bridge is the length of the world's third longest suspension bridge, the main span, behind the Golden Gate Bridge and the George Washington Bridge.

When opening in 1940, the Tacoma Bridge was the third longest suspension bridge in the world. The bridge crosses the Tacoma Narrows and goes to the Gig Harbor Peninsula, replacing the ferry pedestrian commuting from Tacoma and takes 3 years with a total length of 2,800 feet. Time will be created. To save cost, the lead engineer Leon Moisseiff designed a very thin frame that is 39 feet long and has only two lanes. The Tacoma Channel Bridge opened on July 1, 1940. The flow of people in the Tacoma Channel has increased significantly, but many drivers are attracted to paid bridges through not only convenience but also abnormal features of the structure. As they do in the Tacoma Channel, the bridge will swing horizontally as it strikes the wind, sometimes it will experience excessive vertical rise.
