"Ja" sorry, a translation. Posted in error for you. I thought meant jovial apologies. In America not same.
You say it short for donkey rear? In my country similar lingo is hard to work with. Condolences. Perhaps bridge too far.
To the structural engineers listening> What is the upper bound on the length of this type of span? And the width?
Apparently less.
If the world comes to an end. Engineers are always worth more than lawyers.
ANYONE with ANY mechanical sense is worth more than a lawyer.
Sorry should have added...
Just a thought. Trying to stay close to original design profile. And it probably wouldn't hurt to fan out all connections. Of course to save time and money, you could build it to original specs. But I don't know how well that will work...........
Next pic shows redesign using upper pic with...
Apologies yes indeed are in order.
Sorry, bridge and its discussions sometimes can be aggravating.
Please accept my apology.
I shall place myself in timeout. Listen but do not speak.
"ja" is a term from Thailand. It roughly translates to....fight but fight with good reason.
Btw Sym p le your drawing is good and concepts are good. Why not trust yourself?
Vance is good also.
Personally I find the canopy as the better part of the bridge.
The curves, wings and rigidity of it are interesting.
By far of the models I made... canopy.
Truss connections at deck lacking...
Mr Vance I have to disagree with your statement. It must be flawless.
Saying that " With 11 compromised, the load path to the support pylon relied more and more on the canopy from 10/11 north to member 12, and on the deck, from node 9/10 north to the pylon."
I think you are stating the canopy...
The "yoke" concept is related to the same principles as involved in the kitchen.
If an egg is cracked and dropped to far the "yoke" splits wide open upon hitting the pan.
Hence the egg is ruined. Similar and applicable, in laymen's terms.
Sorry. Just had to..................
Guess I'm not quite done.
I can't seem to find inner truce with the crane vibrating question.
The little pixel blow up video was interesting and gave me an idea.
I went back and looked at the video dash cam video link that was provided here.

416-420 - Member 12 moves significantly down-up-down-up as the surrounding deck area warps dramatically.
can you elaborate on significantly?
somewhere between 50 thou and a foot? Like an earthquake?

I'm going to skip over the rag in the wind theory for the puff of magic dust out the end.
and.......let us jump into another fine moment to analyze on this bridge.
The latest comments revolve around tension so lets go there.
If we examine the absolute center of the deck.
2 things should be...
Yes and like I said lets backtrack and analyze these statements...........

Contrary to popular opinion, I don't think the problem was the concrete truss. (weight had nothing to do with it)
It was the design of the concrete truss that was...
I did not mean to steal your idea of the jbar. I've read so much I can't remember everything, sorry bout that. Shout out to Vance one of your longer posts was exactly spot one. I trust you and your thoughts.
Thanks for the video and feedback. I agree crane not lifting bridge.
Although video...
So how about this one......
FIU? Bridge photogrammetry 17 by Zac Doyle also on youtube.
On my monitor, I can see the end of the crane, vibrate what looks like twice.
Can anyone back this up? about at 22 seconds in.
This is exactly when the start of fall begins.
You should see vibration and then...
Has anybody noticed the jbar in the youtube video > FIU Bridge Collapse Lift off of 12 explains J-bar pristine condition < does not match up to the drawing?
Fig 63 in the OSHA report does lead you to believe jbar was not embedded into deck.
In fact by the pics the jbar (in pristine condition)...
