MIAMI (CBSMiami) Florida International Universitys massive new pedestrian bridge collapsed Thursday afternoon in West Miami-Dade.
The bridge, located at 109th Ave and 8th Street, collapsed on a number of cars.
There are reports of numerous people injured in the collapse. At least one person was taken as a trauma alert to the hospital, according to Miami-Dade Fire Rescue.
The 950-ton bridge went up on Saturday. It was then lowered into its final position, just west of 109th Avenue that day.
The main span was built next to Southwest 8th Street.
When quality American companies are used, our construction is good.
Did he blame the NRA yet
Yes, this is the kind of news we USED TO ONLY hear coming from Third World Countries.
Well this didn’t take long....
Design/engineering problem. Prayers for the victims.
Thank you, that was my point. The cure time prior to removal of support, expressed in a number of days, was no doubt included in the specs. It is possible some eager beaver...etc.; that has happened before.
Even a child building a bridge from popsickle sticks would be uncomfortable with the idea of no support underneath or overhead, whether a crane dropped on it or not.
Very few applications in civil engineering would use a safety factor of 5. In fact, structures tend to have lower safety factors than many other applications like mechanical systems, aircraft, etc. because the loads tend to be very predictable.
I loathe and despise liberals.........................
That was my Professional Engineering opinion as well
Whoa! I think I’ll only walk across bridges built prior to say, 2000.
Does NOT inspire confidence.
Wonder if any traffic cams got pics of the collapse...
“My bad.”
It was designed as a suspension bridge, but there was no "suspension" going on after they installed that section over the road.
Usually you build the supporting elements (the suspension tower, in this case) FIRST.
Dade County construction inspectors are notoriously corrupt. As is the entire construction industry. Inferior concrete, insufficient rebar, and paid off inspectors. Especially when it is a public funded project.
This will be the case here, mark my words.
Ah ... good point.
How ya been, Rom?
The bridge was designed by the engineering firm of Oops & Mybad.
With precast concrete, the sections are often subject to more rigorous loading during installation than after they're in place.
In this particular case, it looks like it could just be a simple (pathetic, in fact) matter of the bridge having insufficient support without the suspension tower completed. Who the hell thought this was a bright idea?
If you haven’t come across the posts yet, a witness said that something fell from a crane and that caused the collapse. And other reports that the crew was conducting stress tests when it collapsed.
Nothing confirmed yet, AFAIK.
