I keep reading that "wind" caused it? I don't think so...

If the wind was strong enough, it could stress the metal to the point of failure. Remember Galloping Gertie? |

capttankona, interesting information. I hope we've come further with our technology since the 1940's! I can't believe the small amount of wind we've had recently could do so much damage to the area of the bridge that was just repaired! Pretty shoddy work, I mean really, 7 weeks is all the repair was good for?! that is absolutely ridiculous!

Well, I am not privy to any information about which company and who they hire. So, other then to say with a good strong wind and traffic at the same time, well, you see the results. And I am sure craftsmanship was probably also a factor.

Ch. 4 News has been putting on some real clear pictures of the work,
but I don't have a working recorder right now, so I am missing some good
"Looks" at the work being done. Wind didn't do it.
I question where are the blueprints of this Bridge? Oh yeah, this is Californy.
I hope "They" aren't welding the members so they can't move. They are meant to move, or there would have been rigid members there. I wonder if they are meant to Dampen
any movement that could cause a major catastrophy. Perhaps an earthquake, or the
motion of many vehicles moving the bridge in various ways. Why aren't there a swarm of Engineers there to find out what is happening to that bridge? There are a whole lot more
of those "Eye Bars" on that Bridge. Anyway, thats the way I see it.

One reason for knowing the purpose of the "Eye Bars" is because
the bridge is in constant motion from various external forces, such
as temperature, wind, ground movement, earthquakes, and all types of movement from the vehicles using the bridge. Up and down motion, lateral motion, twisting forces, etc.
One example is when hundreds of vehicles all stop at the relative same time, the force is transferred to the bridge and the bridge will want to move in the direction that the stopped cars had been
going. Much force is transferred to the bridge. much of the force is spread out into the bridge in all directions.
So far I have heard no real explanation about anything. I sure hope there will be a large number of qualified engineers brought in to go over the whole bridge. There are a whole lot more of those Eye Bars on the bridge, plus the bridge is breaking down, and no one seems to come near an explanation.
My best guess is that those members have a dampening effect on the motion of the bridge. My guess too. is that if they are made rigid something will snap. Those bars were designed that way for a special reason, and no one has satisfied my curiosity as to why.

If anyone missed the Tacoma Narrows Bridge Collapse, in Tacoma, W :Pashington,go to Wikipedia, There is much info. Also called, "Galloping Gertie".  |

Very informative heckheckle, thanks for sharing. I hope the engineers have it right this time for the Bay Bridge.
I like your creative use of emoticon: W :pashington

Gee, I guess our local leftists missed this post, which, by the way, is on the same page as yours. If the wind was strong enough, it could stress the metal to the point of failure. Remember Galloping Gertie? Not only that, my link goes right to the Washington State Department of Transportations Tacoma Narrows Bridge History and not some pathetic, weakass wikipedia article on the topic. And if you like his use of the emoticon, you'll really like mine: I g :pt tw w :prds f :pr ya'... |

Cap, I think everyone here is guilty at one time or another of missing a post or two.....no need to get huffy! Anyways, Galloping Gertie is a good example of why they need to get it right. It is still scary that they allowed people on the bridge knowing the job is not done yet...... yikes!  |

Capt kona: It doesn't matter to me who Brought up the name, "Galloping Gertie" first". I just try to point out some information pertinent to the topic I am writing about, in a truthful way, somtimes with a little humor, but you seem to have a flaw in the way you give credit to yourself, even when the truth is just a few sentences back from your Post. Not the other way around as you so state. You claim that you were first to bring up Galloping Gertie as the bridge that collapsed. You didn't Identify the Bridge as the Tacoma, Washington Bridge that collapsed from the Wind because of Fatal Design Flaws. You just stated, "Galloping Gertie", in your Post of: Reply #25 on Oct. 29, 2009, 12:11PM, Page 3. My Post #18 on Oct. 19, 2009, 2:15 AM, Page 2 Identifies the bridge. Aw  go look for yourself. I just point out the folly of trying to make me look bad by some stupid lie. Edit: There are some who seem to think I missed a Post. "Methinks" they make the same mistakes that are done all the time on this forum, in assuming that all the Posts are true, instead of going back a little further to see if there is an older Post that "THEY" have missed. My record speaks for itself  |
