Oct. 1 (UPI) -- Two people were killed and 20 were injured Tuesday after a landmark bridge collapsed on top of three boats in Taiwan, authorities said.

As an engineer, this thing looks like a classic mis-calculation of forces or incorrect material choices. I suspect, that the
conection bolts in the wye joints on either end where not up to the strength calculated amount. The construction team probably
substituted regular cheap bolts instead of using A490 structural bolts for instance. With the design not having a connection
redundacy means that you really need to make sure that the wye connection is made correctly. If you look at the aftermath you can
see the separation of the wye joint at the base of the bridge. If they utilized the correct bolts, this connection would not
separate, but rather distort the joint before separation. Of course I am making this commentary using nothing but the video, but
that is my 2 cents.Comment -

With this and the one at the college in Florida recently (UCF I think?), I'm starting to think twice everytime I cross a bridge or freeway on ramp.Comment -
It cracked like hell.' Engineer ignored warning signs hours before deadly FIU footbridge collapse, report says
Hours before a pedestrian bridge collapsed at Florida International University last year, engineers said cracks in the structure didn't pose a safety concern, according to an Occupational Safety and Health Administration report.
The March 2018 collapse -- which killed six people -- could have been prevented, OSHA said in the 115-page report released this month.
Growing cracks in the structure warranted an immediate closure of SW 8th Street, the street onto which the bridge collapsed, the report said. But the bridge's designers, FIGG Bridge Engineers, after inspecting it that day, said the cracks did not pose any safety concerns, according to the report.Comment -
I doubt it I've been in the engineering business for about 30 years now and can count on an
amputated hand how many women I have encountered in this business. I think the problem is
the CADD software allows for more wild designs that theorectically hold up, but the practical
building of such a structure requires some very specific techniques that construction companies
are not familiar with keeping track of the smallest details in the design. As a rule, let a
structure stand for a year or so before you decide to go under or on it if you can, especially
if the design looks wild. If the structure is a typical design that you have seen before, it
probably O.K. but the crazy shit that looks space age needs to have some service time before
I will trust it.Comment -

Only 2 dead? WowComment -
Lousy gravityComment -
OOOO another crazy structural engineer is on the board eh? lol
They used A490 but they were from China as they were $10 bucks cheaper per box but the equivalent of using duct tape
- even with under designing, this should never happen unless it was a complete gross mis calculation or error in construction, there's too much redundancy in designs to ever have this occur besides a gross penetrate upComment -
Actually I engineer slurry pumps and pressure vessels for oil refinerys and chemical plants. I agree with the
redundancy claim usually but in this case it doesn't look like there is anything holding the bridge together
other than the connection on either end of the bridge. I'm sure there are twice as many bolts as needed in the
connection, but still just the 1 connection to do the job.
We just got a report from the "accident" in Florida FIU campus that states the bridge wasn't designed by a firm
that had the qualifications to do so. I assume that the top engineer there isn't a licensed P.E. and that is
what they are getting at. If this is the case some dudes should go to jail for a while for endangering the public.
My doctor always acts like he is god with all the knowledge of the body and the ability to make decisions over
life and death, and I tell him to take a back seat because he can only kill people one at a time, while if I fuct
something up, I can kill hundreds at a time easily.Comment
