Pipe SmokerFatal pedestrian bridge collapse in Miami
“A pedestrian bridge installed just five days ago has collapsed killing 'multiple people' and trapping cars on the campus of Florida International University in Miami.
The 174-foot 'instant bridge' hailed as a feat of engineering and safety, was installed Saturday morning but was not due to open to the public until 2019.
Television images captured from helicopter show numerous cars crushed by the weight of the bridge. …”

Balzé Halzé"Installed Saturday morning?" A 950 ton bridge was installed in one day? Wow.
And i imagine someone will be going to prison over this.

Something called an "Instant Bridge".

scsigsThat's crazy, will be interesting to find out what went wrong on such a new bridge.

Balzé HalzéJust goes to reinforce my opinion that nothing "instant" is ever really any good.

MNSIGCan you imagine the stress the engineers and builders are going through right now waiting to find out what failed?

walkinghorseWow!!
I was working with the structural engineer whose firm designed the pedestrian bridge in the hotel in St. Louis anumber of years ago. He was the owner of the firm, and was visiting the my site in another city, with another senior engineer who was the head of the firm's office in St. Louis. I believe both of their stamps were on the drawings for that bridge. They received a cell phone call on my old brick phone, and I watched their faces as the call progressed. They both went pale, looked sick, handed me my phone and walked away. Never saw them again! After all of the settlements, I believe they both lost their licenses! I know on our project there was worry and eventually the owner hired a local engineering firm to review their design, drawings, etc. and the city required a complete report and new stamps on everything, including new reviews of all structural submittals.
I heard that the St. Louis pedestrian bridge collapsed because someone missed a connection change on a submittal!

If you are talking about the one that collapsed on New Years Eve 20+ years ago, I believe it was not installed correctly. The walkway was to be suspended on a single threaded rod from top to bottom. At some point somebody changed the design and hung each walkway from the walkway above. A far faster installation but lost all the support. The steel frame of the top walkway could not withstand.all the weight it was holding and the rod slipped out causing the walkways below to fall.

So are the principals of the company that built and installed it, as well as every material supplier involved.

That is a description of the Hyatt Regency walkway collapse in Kansas City. It was always used as a warning to us in engineering school about what happens when we don't do our jobs right. People die. I don't know of any pedestrian bridge collapses in St. Louis in recent history.
Regarding FIU, what a terrible situation for all involved.

YellowJacketObviously very misleading to say it was built in one day. It was installed in place in one day after being constructed next door over many months.

fpuhanJust last week, a friend of mine who is a retired structural engineer, told a story about how a parking garage on which he'd been on the design team collapsed. He said he agonized over it for days, checked and re-checked his numbers, couldn't figure out where he'd been in error.
Turns out they x-rayed the beams and found that no rebar had been used in the poured concrete.
Duh.
You can't truly call yourself "peaceful" unless you are capable of great violence. If you're not capable of great violence, you're not peaceful, you're harmless.

For a 173foot Bridge, that thing was mighty flat and mighty thin. Looking at the pics, my assessment is the roof in the middle could not withstand the gravity forces and the center column punched through the roof causing the whole thing to fail. Don’t know if there were any tension strands in the roof deck. My condolences to the families affected by this tragedy.

Where did you read that it was "built" in one day?

I thought this sounded like the Hyatt skywalk tragedy also.

Just glad it was not a project I was associated with!!
