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.

  • β€ŠStacy 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.

I saw the new Beetlejuice movie. It is fun. Which is probably better than being good. I was pleasantly surprised.

Facebook managed to partially break through Fluffbustingpurity and it's been serving me Kali Yuga memes. How sweet must ignorance be? To know nothing of the world, what bliss!

Most of the symptoms of whatever the fuck happened for the last four, or maybe five, days have abated and now i'm wrung out, sad, and trying to make sense of losing a week to depression and weird bipolar shit and figure out what to do with the remainder of the week. What day even is it? Wednesday?

In my apartment complex there's been an ad-hoc sort of thing going on where useful goods (furnature, old printers, books, etc.) get left next to the dumpster, and often people leave food items like rice and cans and stuff in the laundry room. Every time I come back from the laundry room with an atlas of human anatomy, or a bag of apples, or a jar of peanut butter my wife looks at me like I'm crazy, but hey, it's free peanut butter. I scored a 55" flatscreen TV by that dumpster once!

what these "revolutionaries" don't realize is that the easiest way to get to power is to simply identify with the people already in power

Saw a lib in my neighborhood had a lawn sign that said, in the Kamala colors and font, "I Understand the Assignment". Really leaning hard on the smug overachiever college student thing.

Crank belief: frakking technology should be used to build state-owned geothermal plants all over the country, unlocking the practically limitless power of the Earth's mantle and solving the climate crisis at the same time.

I get the impression that most people don't get caught in moral quandaries that cause them to retreat from the world in a state of emotional overwhelm

But I do get caught in this assumption that if I explain myself perfectly then it'll click and somebody will see me as I truly am

I also don't get how people ask questions without being scared

cooking bratwurst is so boring, fuck. It's that and hot dogs tomorrow. Artless. Just sweating all day and putting char marks on shit.

I wanna see some fucked up German Thai fusion where it's brarwurst but all lime and peanut and cilantro and shit. why are people so uncreative with the infinite food possibilities before them

Instead of electrification and the eglinton LRT, GO should be investing in massive arcologies near each station.

burning the midnight oil? no, cookin' the midnight chili

i say chili but really any chili purist would call it an unholy abomination, as I've thrown things in there what should not be in "chili," but my current mode is "chili is just a chili flavored ratatouille, it's all just savory vegetables and protein stewed in tomato sauce." i laugh it those who freak out over beans in chili, there're beans in mine, some mashed up with a spoon (you can eat the beanis, and it's a useful thickener) but also random ass shit like a bit of cardamom, and a big fistful of mashed potatoes (hello more starch thickening, plus all the cream and butter and milkfat loaded into that shit) and yknow what, it probably tastes good. i'm lettin that shit ruminate

CW: more explicit meat mentionthis is what I'm doing with some leftover brisket chunks I took home lol

the "haitian immigrants eating cats and dogs" thing is fucked up in general, but it would be funny if it came about because someone confused haitians with asians (the immigrant group more often associated with that stereotype) just because the words sound similar
