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.

Auto generated text summaries of papers/documents are worse than nothing. I don't mind if I search a paper's name and there is no discussion anywhere online. Just don't make me sift through pages of barely coherent "summaries" of the paper's abstract to find out that's the case. I hate the internet and internet search, it's officially become worse than useless. Like I'm spending time to walk away with zero information gained.

I remember hearing a comment about a study where participants would sit in front of a projector, then a POC was projected; white participants would have a cortisol spike, nonwhite participants had no response. Can't seem to find it though. Anyone heard of it?

train-shining Attention Hexbear Hockey fans! In about 15 minutes Lokomotiv Yaroslavl faces off against Kunlun Red Star! Will Lokomotiv keep their momentum and chalk up another win? Will Red Star derail Lokomotiv and hand them their first loss since the season started? Who will you cheer for? I think my bias is obvious but

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.

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

I want to make a chud meme and it's the one where you do the thing and the dog gets angry and it's like

European dude; attaches a wedge to a leaver

and then the dog is like "European governments" and looks cross

and the captiion is knife crime or something idfk.

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