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.
>>They might want to stick with what works.<<
Or at least field test a real one in a less dangerous situation like over a river that needs 10 feet or so.
I cannot believe they field tested this in production. You would think they were (red dot) Indians who did this.
Rush just talked about it on his show.
Safety Factor - If the calculations show it will fail with a load of X, you design it to withstand a load of 2.5X. That’s the “margin of safety.”
Las Vegas has a lot of experience with pedestrian bridges.
They should have contracted with whomever builds those.
This thing was just pure poor construction and design apparently...
Should have used Reardon steel...
Were turning into a third world country.
Figure out how strong you expect it needs to be, then multiply by 2.5 to take into account the things you weren't expecting.
Wonder how many that worked on the bridge were illegals?
Their website is shutdown, but here is from Bloomberg: https://www.bloomberg.com/research/stocks/private/people.asp?privcapId=4361441
Who had the low bid on that job?
They’re a local company here. Built the Zakim Bridge in Boston and the Sunshine Skyway Bridge in Tampa. Owned now by a woman and created by her Father.
It was unfinished, not scheduled to open for another year................
Rileys research interests include engineering and social justice; engineering ethics; social inequality in engineering education; and the liberal education of engineers. In 2005 she received a National Science Foundation CAREER award on implementing and assessing critical and feminist pedagogies in engineering classrooms. Students in Rileys research group are pursuing interests including culturally inclusive pedagogies; understanding faculty motivations and approaches to teaching engineering ethics; connections between critical thinking and engineering ethics pedagogies; engineering education policy; and public participation in engineering projects impacting communities.
I’m assuming Florida International University is not an engineering school ...
Note to self: Don't take the Zakim Bridge and the Sunshine Skyway Bridge.
Chinese steel?
My very first thought. Inferior concrete is also a possibility.
The department of engineering “eduction” is not a part of any Engineering Curricula or department of college. It is part of the college of education for certification as a High School teacher. Sort of like getting a degree in Business Education is not in the College of Business.
Universities have fallen in the US but not as far as this article or its’ responders imply.
Judging by the looks of the abutments, the bridge had not even been finished yet.
