NFT: I-35W Mississippi River bridge collapse

Zebrka : 5/29/2016 3:00 pm
On Wednesday, August 1, 2007, the Interstate 35W Mississippi River Bridge in Minneapolis, collapsed into the Mississippi River around 6:05pm CDT.

I typed all that. Anyone remember this? I can't even htink of how it would be to see something like that....emotonal

Of course I remember that happening. Kind of a strange time to bring this up, but driving over a bridge everyday to go to work, I couldn’t imagine it just collapsing and —there I go! Into the water! Route 9 dies on Route 72

No, those two are mutually exclusive but undeniably true.

what caused your brain synapse to suddenly fire up to post about a random event from 9 years ago.

Not timely  
Sarcastic Sam : 5/29/2016 4:21 pm : link
but interesting enough. This collapse highlighted vulnerable bridges within our aging highway system, and in part triggered the replacement project for the Tappan Zee Bridge.

A general thread about decaying infrastructure citing this as an example would not have met this type of reaction.

in bridge collapses, there is some wild video available of the Tacoma Narrows Bridge going down in 1940. You can see the span acting like a wave.

Interestingly enough, that span was very similar in design to the Whitestone bridge. They ended up adding large steel trusses to the Whitestone bridge in response to the Tacoma Narrows collapse... ironically the extra weight probably caused significant strain on the cables and was removed about 10 years ago.

Mohamed Roble was weeks shy of his 11th birthday when the school bus he was on plummeted more than 30 feet as the bridge beneath gave way.

Now, according to court testimony in a federal terrorism trial, Roble - one of the 145 people injured in the Minneapolis bridge collapse that killed 13 people - is believed to be in Syria with the Islamic State of Iraq and Syria, or ISIS.

If I remember correctly the Tacoma Narrows collapse was precipitated by steel panels in the side of the bridge that did not allow winds to travel through the structure. I might be mistaken, but I believe that this design flaw was the reason for the collapse..

Galloping Gerty was the nick name. The bridge had a solid roadway which allowed the wind to sail it until it collapsed.

Al that Tacoma narrows bridge collapse is a very, very famous one that was used as recently as when I was a HS sophomore in physics class as an example of harmonic motion, 45 years ago...
Looking at some recent material on this  
Big Al : 5/30/2016 2:45 pm : link
it is now thought that the textbook explanation concerning resonance was incorrect for this bridge and the collapse was caused by "wind-driven amplification of the torsional oscillation".

Isn't oscillation an example of resonance?

Without looking it up, I think it is the reverse. Resonance is a type of oscillation where the natural frequency of the object matches the frequency of the external source.
That sounds right Al.  
BlueLou : 5/30/2016 2:59 pm : link
So now the big heads don't think actual resonance was involved?

I've seen some great graphic representations of resonance - oscillation building on itself - in tidal wave simulators.

Isn't it great when the kids forsake Disney false comedic drama for an afternoon and go Nat Geo or Science?
Even in my chemical engineering curriculum

they made us takes courses in physics, mechanics, structures (the domain of civil engineers), etc. I guess that is a different type of well rounded education than what liberal arts people get.

Japan having a Tsunami, and Louisiana a hurricane.

But don't worry, with 60,000 structurally deficient bridges and tunnels in the US, we will get some more collapses real soon.
