Nice pics[edit]

In http://lib.washington.edu/specialcollections/collections/exhibits/tnb/aftermath there are some nice pics about the TN brigde. I have written them. I hope they will allow us to post some pics to the page.

Reversed Photo[edit]

The color film frame from the bridge collapse movie appears to be reversed. The still appears to have been taken to the left of the collapsing bridge, while the motion footage included on this page is taken from the right.2001:558:6011:B:5051:F65D:36F0:7127 (talk) 22:48, 3 September 2013 (UTC)[reply]

External links modified[edit]

Hello fellow Wikipedians,

I have just modified one external link on Tacoma Narrows Bridge (1940). Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20070427192736/http://www.citynoise.org/article/5410 to http://www.citynoise.org/article/5410

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

Y An editor has reviewed this edit and fixed any errors that were found.

Tacoma Narrows Bridge in popular culture[edit]

Pioneer used footage of the bridge's collapse for one of its commercials a few years ago — https://www.youtube.com/watch?v=K_Eib49uPyc — Preceding unsigned comment added by 209.232.103.85 (talk) 17:59, 12 August 2022 (UTC)[reply]

Ammann Quote:[edit]

This quote is attributed to Ammann in the "A Lesson for history" section and cited as being from the 1941 failure report:

The Tacoma Narrows bridge failure has given us invaluable information ... It has shown [that] every new structure [that] projects into new fields of magnitude involves new problems for the solution of which neither theory nor practical experience furnish an adequate guide. It is then that we must rely largely on judgment and if, as a result, errors, or failures occur, we must accept them as a price for human progress.

This quote does not come from the failure report, rather a 1944 presentation given by Ammann and published in the Journal of the Boston Society of Civil Engineers.

The thought I should like to leave behind is that bridge engineering is not, as popularly assumed, an exact science. While ordinary structures are closely controlled by ample experience and experiments, every structure which projects into new and unexplored fields of magnitude involves new problems, for the solution of which neither theory nor practical experience can furnish an adequate guide. It is then that we must rely largely on our judgment and if as a result errors or failures occur we mu t accept them as a price for human progress. link to journal

Unless the first can be provided with a source, it should not be attributed to Ammann. It has been used since September 29, 2008 when it was added by @Diegotorquemada. I am unsure where he found the quote, but it is not present in the 1941 report as he cited. This quote, as written on wikipedia, has to my knowledge been quoted at least twice, once by Structure Magazine, and once by Vice, each time citing the 1941 report, which it is not present in.

I will be fixing the quote to reflect Ammann's actual words from the 1944 publication, but it is perhaps best to use a different quote, as it is not speaking specifically of the Tacoma Narrows Bridge, rather the field of Civil Engineering as a whole.

pics of new bridges[edit]

The article in the Slovenščina version contains a photograph of the 2 current bridges, which ought to be also in the English version. Kontribuanto (talk) 07:47, 30 March 2024 (UTC)[reply]

More recent explanation[edit]

I think the explanation section for the collapse of the bridge should refer to the following paper and to the explanation within it: "On a class of bimodal oscillations powered by a steady, zero- frequency force—Implications to energy conversion and structural stability". It explains how a zero-frequency force such as that of wind, can drive a resonant system, such as a bridge, based on two coupled modes. Michaelior (talk) 04:31, 24 April 2024 (UTC)[reply]
