Boomers are the best at it

```The engineers believe FIGG significantly misjudged what would happen when a large amount of structural stress was placed on a single diagonal strut — a concrete brace that helped support the bridge — at the north end of the 174-foot span. That resulted in an undernourished strut and anchor that could not adequately bear the weight of the bridge and the substantial forces placed on them when the span was lifted into place over two support piers, the outside experts said. That joint is precisely where the bridge appears to have failed — and where potentially worrisome cracks began to appear even before the bridge was installed over the eight-lane road on March 10.```

```The Silver Bridge was an eyebar-chain suspension bridge built in 1928 and named for the color of its aluminum paint. The bridge carried U.S. Route 35 over the Ohio River, connecting Point Pleasant, West Virginia, and Gallipolis, Ohio.

On December 15, 1967, the Silver Bridge collapsed while it was full of rush-hour traffic, resulting in the deaths of 46 people. Two of the victims were never found. Investigation of the wreckage pointed to the cause of the collapse being the failure of a single eyebar in a suspension chain, due to a small defect 0.1 inches (2.5 mm) deep. Analysis showed that the bridge was carrying much heavier loads than it had originally been designed for and had been poorly maintained.

The collapsed bridge was replaced by the Silver Memorial Bridge, which was completed in 1969.```

At least it was an analysis of a strut instead of a misplaced load on a bolt

Welp guess we gotta go knock down all the bridges now

```Statement from FIGG Bridge Engineers, Inc.

“We are stunned by the tragic collapse of a pedestrian bridge that was under construction over Southwest Eighth Street in Miami. Our deepest sympathies are with all those affected by this accident. We will fully cooperate with every appropriate authority in reviewing what happened and why. In our 40-year history, nothing like this has ever happened before. Our entire team mourns the loss of life and injuries associated with this devastating tragedy, and our prayers go out to all involved.”```

So... what changed?

Why all of a sudden were they so shitty at bridges?

What did the NTSB say about it, as they were tasked to investigate.

You don’t misjudge the load in Kips

You miscalculate, not misjudge

When was that released @stedly ?

They waited until the investigation was done before coming to any conclusions as well as to avoid any political shitshow.

Imagine had that shit been said on Fox or OAN @Mr. Sofaking Fluffykins

Hempcrete is literally a meme holy shit.

Why fluffy

why you do this?

>environmentally friendly concrete mix

Yeah until it collapses on your head.

doesnt it have like 1/20 the compression strength of concrete?

1 MPA

do you have the stat sheet on it?

def aint building much with it withought other materials to support it

would be good as filler tho

Be great as an insulator

but its "breathable"

I wonder if it retains water
