Tacoma Narrows Bridge was constructed in the US in the city of Tacoma in 1940. In addition, Interesting Disaster Tacoma Narrows Bridge happened in just four months after the introduction of the Tacoma Narrows Bridge. Interesting Disaster Tacoma Narrows Bridge images were taken during the collapsing. The pics were so interesting. The event took up the agenda for a long time.In the Washington of US, in 1940, the suspension bridge collapsed due to the storm… The collapse of the bridge showed the bug in the civil engineering field. Therefore, Interesting Disaster Tacoma Narrows Bridge have come valuable results.
Interesting Disaster Tacoma Narrows Bridge that was completed just 4 months after 7 October 1940 and it was destroyed by a 42 miles per hour storm. The strom starts to shake the bridge as if washing linen in the hands of two people shaking.
Nowadays: the construction engineer and also in part by machinery and architecture professors are often shown the event as a example of mechanical vibration in the related courses…On the other hand, the bridge collapse images have gained great attention and fame at the memories.When the collapse of the bridge under the existing information showed that engineering courses required big updates on the related knowledge.
Tacoma Narrows Bridge was the world’s third-largest span suspension bridge when it was completed. 853 feet from the middle span width of only 11.9 meters. Shortly after opening, even in very light winds (6-9 km/h), it was observed that the left-right and up-down swings. Therefore; people gave the bridge name of “Galloping Gertie” after the installation.
Technically, 07 November 1940 not blowing very strong (about 67 km / h) destroyed resonance came a windy day. According to the project 140 km/ h winds should be durable. Before, the bridge due to the wind speed frequency of 0.6 to 0.5 m up and down oscillation started. After returning like 0.2 speed (torsion) has started oscillation. During the right side than the left edge takin release 8.5 m above and below. The oscillation frequency of the proper blowing in the wind increasingly violent results have coincided with the natural frequency of the bridge, the bridge collapsed.The traffic was closed before the bridge collapse, except for a dog in the car on the bridge.
There was the man who escaped and survived in an interview on the subject in the below picture.
