RIP Tubby :(

RIP Tubby.

"Tubby" the dog fell into fame when Galloping Gertie collapsed on November 7, 1940. As the only victim of that great disaster, Tubby has earned a special place in the hearts of many. His death symbolizes the drama of that terrible day. All that is known about the unfortunate pooch is here. These few facts are a small but meaningful way to honor his unique place in history.

Even with the "normal" oscillations I wouldn't drive on that!

WSU Press; Hobbs, Steve; "Catastrophe to Triumph: Bridges of the Tacoma Narrows" p86. 2006 Indication that a slipping cable band on the North main cable caused the center span to oscillate sideways resulting in span failure.

We are studying waves and our professor showed us this

Many thanks for your contribution hwyfan.

The fatal torsion that wrecked the bridge on November 7, 1940 after one of two mid span braces placed between the cable and the girder as a temporary securing measure slipped. They were intended only to be temporary braces until permanent brackets could be fashioned. They were placed there at the suggestion of engineer David Steinman, who used them on his Thousand Islands span in 1938 when it started exhibiting wind torsion.

If you listen closely, you can hear the suspension cables making whipping noises in rapid succession.

hwyfan 2 anos atrás A torção fatal que destruiu a ponte em 7 de novembro de 1940 após uma das duas chaves de span meados colocados entre o cabo e a viga como medida de fixação temporária escorregou. Eles eram destinados apenas para ser chaves temporárias até suportes permanentes pode ser elaborada. Eles foram colocados lá por sugestão do engenheiro David Steinman, que os usavam em sua extensão de mil ilhas em 1938, quando ele começou a expor torção vento.

That is crazy!!

Yes; poor old Tubby; the only fatality cause by the demise of the Tacoma Narrows' Bridge.

Imagine being the person to get *THAT* call

Mario Salvadori has written a couple of books on structures for the lay reader which should be in the library of anyone interested in structures.

Interesting!

how come the bridge is swaying... is it that weak (before the collapse)

That poor Dog

Poor lil doggie. 😢💔

Ah, the demise of "Galloping Gertie".

Is it due to Resonance?

Leon Moisseff was not the leading suspension bridge designer of the era. The Tacoma Narrows was in fact the first span on which he was chief engineer and designer. Othmar Ammann was the greatest designer of the era. Moisseff died in 1943, three years after the Tacoma collapse.

Did the dog die because last one the dog suvired

Thomas vindt de brug leuk

Such UGent, much movie

Tubby:C

poor gurdy lol

I am glad that you found it interesting

I disagree strongly with the idea that it took 52 years to find the cause of the disaster. The concept of alternate vortex shedding was very well known long before 1992. Indeed, it was taught during my time studying Civil Engineering at a UK university in the 1970s. One of several exemplars used in this teaching was the Tacoma Narrows bridge.

Sorry about the guy in the car..

Yes, I agree with you.

Resonance of structures can cause the failure of many different structures, from wine glasses to tall buildings, and from aircraft to submarines, and very many more structures. To see other structures resonating on my youtube site, Google "carltfross youtube" to access my youtube site.
