Bay Bridge in an Earthquake

Simulation of the newly opened Bay Bridge in San Francisco in an earthquake. Pretty interesting to see the engineering that allows the bridge to twist and flex.

woww?
Disgruntled, old? timey pappy?
Love the new bay. Good Job, The Engineers? did a good job. -NK-
Maybe it will crumble, all the steel is from? China.
Why do people choose to suicide? off the gg
tisaumi might take the bridge down?

cool vid, but what’s gonna happen to the second part of? it that goes from YB to SF…
A .6 quake? That’s less than a 1.0 quake?
Somebody didn’t take? their happy pills this morning.
Nothing is earthquake-proof; “earthquake-resistance” is the goal of modern engineering. Contrary to the astonishing number of uninformed comments in this stream, known component-manufacturing issues have been or are in the process of being mitigated. Even without mitigation, the new bridge is many times more earthquake-resistant than the old one.
Not going to use this new beauty? Great! More room for me!
For anyone actually interested in facts,? they are easily available at various online sites.
I don’t care about your video, you are all untrustworthy, this entire system is corrupt. There should be a moratorium on removing the old existing bridge that was constructed by our AMERICAN FOREFATHERS, using honest American made, materials and loyal,? patriotic, legal, American citizens and immigrant labor. My prediction is that the first .6 earhquake or above will cause a closure at best or a catastrophic collapse at worst.
Iris, I’m glad we have structural engineers like you to comment on our civil projects and question the general intelligence? of Americans.
Won’t matter? if the quake is big enough…
I hate it? when I get battered piles.
It’s called AMERICAN ENGINEERING, stupid ignorant. Exactly why many of our bridges, tunnels and buildings have lasted for more than 75-100 years, not those cardboard bridges in whatever third world nation you live in.
Are you an engineer?? Yeah, just keep? working at your Wal-Mart.
The new bay bridge opens next week.Hope those new bolts hold up as they had to be replaced before this bridge was even finished.. I’m in Oakland,think I’ll take one last drive on the old bridge before they close her down for good,great memories….except when her? top 50 foot section collapsed during the 89 quake.Oh well,we’re only human right?
Just looking at the smallness of the pillars holding up this bridge sends shivers down my spine. What? Is the leverage less than two feet? Imagine an earthquake rocking back and forth…you have 2? feet & 4 feet and 2 feet by 2 feet or four feet by eight feet…which pillar will be able to hold the bridge during a slide? Are you Americans that stupid? Then, there is the water which is moving the sand away from the base and tipping the pillars? Which bridge would u like to use?
Are you guys? still together 3 years later?
They are almost done ! ?
Has? fishing been confirmed to be.allowed on the.new.bridge?
Are they done with this? bridge or what?
I agree it’s been a huge debacle, but even with it’s shortcomings and flaws, it’s still far safer than the original span.
That said, they could have built this far safer, simpler, faster, and cheaper if they had just? gone with the original plan for a simple causeway. Unfortunately Oakland bitched and moaned about getting another ‘ugly’ bridge and demanded an architecturally unique span. Like that’s gonna make Oakland seem nicer at this point. Whatever.
Get a room!?
Confidence in? the new bridge is incredibly low. Moisture caused giant bolts to pop out of place with no earthquake or even traffic causing any stress. I won’t ride on the new bridge when it opens.
hahaha hinge pipe beam
I live? less than a mile away from the San Andreas Fault line, yeah buddy
