Building implosion

In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings. Despite its terminology, building implosion also includes the controlled demolition of other structures, like bridges, smokestacks, towers, and tunnels. This is typically done to save time and money of what would otherwise be an extensive demolition process with construction equipment, as well as to reduce construction workers exposure to infrastructure that is in severe disrepair.

Building implosion, which reduces to seconds a process which could take months or years to achieve by other methods, typically occurs in urban areas[citation needed] and often involves large landmark structures.

The actual use of the term "implosion" to refer to the destruction of a building is a misnomer. This had been stated of the destruction of 1515 Tower in West Palm Beach, Florida. "What happens is, you use explosive materials in critical structural connections to allow gravity to bring it down.

The term "implosion" was coined by my grandmother back in, I guess, the '60s. It's a more descriptive way to explain what we do than "explosion". There are a series of small explosions, but the building itself isn't erupting outward. It's actually being pulled in on top of itself. What we're really doing is removing specific support columns within the structure and then cajoling the building in one direction or another, or straight down.

  •  Stacy Loizeaux, NOVA, December 1996

Building implosion techniques do not rely on the difference between internal and external pressure to collapse a structure. Instead, the goal is to induce a progressive collapse by weakening or removing critical supports; therefore, the building can no longer withstand gravity loads and will fail under its own weight

Numerous small explosives, strategically placed within the structure, are used to catalyze the collapse. Nitroglycerin, dynamite, or other explosives are used to shatter reinforced concrete supports. Linear shaped charges are used to sever steel supports. These explosives are progressively detonated on supports throughout the structure. Then, explosives on the lower floors initiate the controlled collapse.

A simple structure like a chimney can be prepared for demolition in less than a day. Larger or more complex structures can take up to six months of preparation to remove internal walls and wrap columns with fabric and fencing before firing the explosives.

Charlie Kirk hasn’t tweeted about 9/11 at all today does he hate America

[–] Coolkidbozzy@hexbear.net 4 points 23 minutes ago

this is what is going through the heads of all public figures rn

[–] Comrade_Mushroom@hexbear.net 11 points 1 hour ago* (last edited 1 hour ago)

Wow, everyone has such nice words to say about someone who made an entire career out of normalizing hatred of - and violence against - the innocent. What a wonderfully accepting and inclusive society we must have.

There's video floating around on TikTok (and by extension, Reddit) showing what looks like Trump having a stroke during the national-mourning-period festivities

Reading lib comment sections and someone posted that “we just need to accept some gun deaths” Charlie Kirk quote. Other commenter responds “I’ve been seeing this quote everywhere, what’s your point?” OP responds with the (very obvious) point that it’s Charlie Kirk pretty much saying we have to accept his death. Other commenter responds, “ok, thanks. I think I’ll wait to hear his take before I respond to you.”

My man, I don’t think Charlie Kirk is gonna be having any takes any time soon.

Vibe coding is going to bite so many programmers in the ass down the line

[–] hexaflexagonbear@hexbear.net 8 points 1 hour ago (1 children)

Even if you want it to be a part of your workflow, it’s crazy that it’s encouraged at the school and junior levels. You should learn to read, write, and debug code! Figuring out how to say pretty please write my code to a chatbot isn’t difficult enough to merit dedicating time early in your career to learn it, and if you don’t have the skills to reason through the output it’s less the useless.

[–] hello_hello@hexbear.net 3 points 8 minutes ago

Its not encouraged at my university but students use it to cheat anyway.

I guess making every computer product an unknowable box of ads and spyware while the entire economy is being propped up by grifters doesnt make for the best students.

The "learn to code" wave being treated as a ticket to a better life (see labor aristocrat, bourgeois) is horrifying.

[–] SummerIsTooWarm@hexbear.net 8 points 2 hours ago

I was browsing the wider reactions to the funny thing yesterday on the fediverse with my lemmy.ml account, and I have to say that I'm positively surprised. I expected much more stormfront-esque pearl-clutching about the dead fascist. But no, most things I found could have come from here, lots of celebration and memes. Even accounts from lib.world, libfed.social and fa.sh.works were mostly ok.

Just wanted to make the observation, not recommending to refederate or anything. Just expected much more lib reactions to it.

[–] ClathrateG@hexbear.net 19 points 3 hours ago* (last edited 3 hours ago)

54 comments(none from me) and counting arguing under my fb status 'rest in piss Charlie Kirk' lol

Not gonna lie, it's kinda bullshit that I HAVE TO take my UNPAID thirty minute break or else I get managers up my ass over it

I pretty much can't take a break until lunch is over and like, if I want to just fuck off and go home at that point I should be able to instead of having to clock out, eat, then wait to clock back in just to clean up and go

Is mao a lib for not killing puyi?

Premtive, This is a joke no-no-no-wait-wait-wait

Mao was a lib for not nuking Chiang Kai-shek's headquarters in Taiwan.

The cool thing about the AI era is they’re not only trying to replace call center support, but even the automated systems that had already existed are much worse than before. I just tried to get a package held for me with UPS and instead of having me punch in the tracking code with my phone pad it wants me to say it out loud, and it is terrible at figuring out the tracking code. Lots of number letter confusion that should be caught by validating if it’s the expected character type for the position. Stop hiring “cracked” ML engineers who just graduated, this shit was functioning perfectly fine a decade ago. Please rehire your software engineers that actually knew how to do their jobs.

The chatbots also put up more resistance before forwarding you to staff now. And as I’ve said, these things are just notably worse than pre-llm, which is fucking wild. I don’t even necessarily think it’s a weakness of the language model, it’s because corporate is so bad at separating out grifters from actual engineers and these systems are built by the dumbest MBAs who took a single random “AI” “certification”.

Seriously contemplating moving to a cabin in the woods before this cycle catches up to us enough that planes, trains, and automobiles start exploding on the regular.

They are still selling American Comeback tour T-shirts.

It's fitting, that debate was ended by a quintessentially American comeback.

[–] Le_Wokisme@hexbear.net 6 points 3 hours ago

we should sell "american clapback" shirts with a picture of the gun on it

Don't forget about the original and more important 911. Allende, his comrades, and all people that were robbed of their project only to then suffer under a US backed dictatorship, I hope your dream someday comes to fruition fidel-salute

[–] Des@hexbear.net 9 points 4 hours ago

ok going hiking in the mountains to celebrate ~~9/11~~ Charlie Kirk Day. i'm sure when i return we'll get to see all the messages written and learn it's antifa and the dems are now a designated terrorist org

the libs will show their bellies, accept their new status and let themselves get mass arrested, and all run as independents in a permanent one party state

ugh yeah hopefully there will be no cell service

Something about Charlie Kirk posts being liked by everyone in my LinkedIn network seems ominous to me

What the fuck does Charlie Kirk have to do with employment

Actually, scratch that, duh. This is consent manufacturing in action. I mean, the fact that Trump was the first to break the news tells all. Fuck

[–] Rojo27@hexbear.net 13 points 4 hours ago (1 children)

I feel like the LinkedIn types would love him a way. After all in their eyes he was probably just a successful smol bean entrepreneur who built Turning Piss into one of the more recognizable right-wing alternative media/think tanks. LinkedIn is a fucking capitalist cesspool anyway.

One of the best feeling days in a while for me. wholesome. I wish to wake up to such good news every day.

[–] ShimmeringKoi@hexbear.net 10 points 4 hours ago* (last edited 2 hours ago)

I went for a bike ride last night and felt the hopeful air I haven't felt since childhood. I realized then that it wasn't the innocence of youth I was missing, but the feeling of hope for the future, and that those feelings are absolutely not locked forever in the past. It was a feeling of immense relief, like a claw around my throat loosening just enough for a tiny breath of air. This life can be more than just waiting to die.

The r/conservative Charlie Kirk mourning post appears to have 41 poop emoji reddit gold stickers on it. Am I seeing that right?
