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.

Lots of meta drama with people upset over mods recently, so I want to say: thank you mods. You do tedious, thankless amd largely unseen work. You keep this website safe. I appreciate you.

To everyone: please do something nice for yourself today, you need it, you deserve it.

thing meant for phones has a web app (extremely rare)

try to log in

it wants you to use the phone app to log into the web app

Wtf, I'm using the web app cuz I don't have the phone app

Death to the web, death to phones, melt down all computers made since 2000, make HTTP illegal, send all {Java,Kotlin}{,script} (all the same thing) developers to reeducation camps

I don't understand why I am sweating through every piece of clothing just enough to leave ugly stains. We simply do not have the science to answer such a thing.

It's very annoying though. Nobody else looks sweaty 😐

Seeing 9/11 happen: is this loss?

[-] allthetimesivedied@hexbear.net 14 points 2 months ago

I’m watching a friend’s van while he’s staying indoors temporarily. He’s actually paying me in cash (and other things) and I basically get room and board in the form of a cabin-style tent next to the van.

Mention of drug useHe’s also really cool. First homeless person I’ve met in a long time who isn’t either racist nor extremely nihilistic about racism. He’s the first person I’ve met in a long time who does drugs and doesn’t twack out and say stupid shit. He really likes me for some reason.

HornyBut his girlfriend—who’s also really cool—is really hot and not only looks like my ex-friend but sounds like them and has the same biting sarcasm as well.

This kills the crab.

But this cushy deal might be ending in a few days. Sadface.

It hurts me to see people take the immigrant pet crisis so lightly. There's plenty of police reports regarding the 20 eaten pets/day. Google police 20 pets per day and you'll see the evidence clear as day.

Come to think of it, worms aren't really social animals and they don't seek companionship as far as I'm aware, so The question you should be asking me isn't "Would you still love me if I was a worm", but "Would I still love you if I was a worm" thinking-about-it

Peru's former dictator, Alberto Fujimori, died on Wednesday afternoon in Lima. Fujimori died in freedom, after receiving a questionable presidential pardon, and with millions of soles in debt in civil reparations, which were never paid to the victims of his crimes. He did not beat cancer.

My personal 9/11 happened tonight. I was at the door of the place where the speed dataing event was taking place and I changed my mind and went homenegative

Just feeling tired and a bit burned out. Not sure what possessed me to buy tickets to two speed dating events on back to back nights. I guess since I was opening there was little chance of work getting in the way of me going, but ugh. I should know myself well enough to not do that.

I've just learned that there's an urban legend in Brazil that 9/11 interrupted the airing of an episode of DBZ on some TV channel. And, at the same time, they also interrupted an episode of Sailor Moon R on another TV channel. lol

Little jarring watching Blazing Saddles and the hard R comes out.

Love this movie, though. Couldn't make it today because of Woke.

Idk if this is the case in other imperial core countries, but is it just me or has the US practically invented a Hukou system of its own? Let me explain:

  • rents/housing costs are surging higher and higher and this is seen as a good thing because “muh invoostment! Muh equity!”. Now, unless you’ve been a homeowner of a city for decades or a child growing up in that city. Cities are now just giant country clubs and the rest of us are practically confined to rural, reactionary shitholes. What does this mean? Well, if you’re a child growing up in say, LA. You will have more access to connections and resources that will help you in life. If you’re not all that lucky and born in a red, middle America state you get to eat shit. Yeah, “connections” are important (almost too important) but if you’re not one of the good ol’ boys, good luck even getting a job as a dishwasher.

  • While this is arguably more understandable, in-state and out-of-state tuition is absurd, so again if you’re born in a red state that values education much less than blue states, you once again get to eat shit. With ~~benefiting from a modern day spoils system~~ sorry, “networking” being touted as the only way to get a job, going to a no-name university will be held against you. Take it from someone who wants to go back and get a master’s just to try to get porky’s attention.

  • You know the saying “it’s expensive to be poor”, well that also extends to being born in a poor rural county. Rural folk are forced to put up with car dependency and usually only have access to shit-tier amenities and shopping. Let’s take Uniqlo vs JcPenny. Uniqlo is a clothing company that makes somewhat decent clothing for a fair price. However, Uniqlo is always exclusively in major cities with the smallest city they’re in within the US is Sacramento IIRC. Meanwhile I’m sure many fellow poor people that came from places not on the map can relate to having to do back-to-school clothes shopping at Target or JcPenny, which are practically disposable, frumpy-and-proud clothing. Sure, you can order online from Uniqlo anywhere but the point is that these cities that rich people want all to themselves have services that will save them money in the long run AND be better quality.

  • Location discrimination in hiring. Porky’s infamously extremely selective on the few times he needs to hire someone at all, and many porks seem to have a “local’s only” policy, and one article I read mentioned a guy being discriminated against because he lived in a rural part close to the city he couldn’t afford to live in. The porks were confused “why anyone would choose to live there” and didn’t want anything to do with him.

So to me, it really does feel like I am stuck in a reactionary part of the country and I have no choice but to put up with it. We constantly have to hear how bad blue parts are, but the rich seem to want to do everything they can to stop poor red staters like me from moving to them.
