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?

Up to 175 on my squat, which feels great. It does not feel great to be surrounded by 20-somethings who are lifting twice my weight every time I go to the gym. Just gotta remember that it's not about that. They've been at it longer than I have and they're younger. It has been nice to start noticing that my pants are falling down. Failed some of my bench press reps at 125, which is frustrating because I'm hungry to get the plates on there, but it's a process I guess. Think I gotta audit my diet to just see where I am and if I need more protein.

One thing I'm not sure is real or not is that my facial hair seems to be growing like crazy. I don't know if it's just getting older or if I've got more testosterone from the lifting. Like I'm feeling some other effects maybe that are in line with that. Mostly it's just annoying to shave more often. But if some hormonal decisiveness is helping with my executive dysfunction, that's pretty tight.

another agency in my city tryna poach ya boy big-cool first time i've ever been hit up by a recruiter unprompted, makes me feel like a bit of a hotshot. my new job/promotion is Fine but a little stuffy, and these other positions might bring me closer to communities i grew up in/around so can't hurt to hear them out.

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

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?

almost started a mini struggle sesh in the mega about whether being a short guy is a disadvantage in dating following another thread. got some food in me and thought better of it. but fr the short version is that some of ya'll are omega coping as an overcorrection for incels coopting a very obviously real and socially acceptable form of body shaming that is rooted in patriarchal conditioning. got more extra in my previous draft but that is the short version, it's a completely valid thing to feel insecure about/to have body image issues about.

i don't even want to be taller i like my height so miss me with that shit. i like feeling like a pretty little half elf prince of thieves. but i'm also realistic about how it effects my prospects with cishet women.
