Best Laid Plans

When things go wrong despite reasonable planning it’s embarrassing. I’ve never blown up a structure but these guys got it wrong somehow. They weakened the structure severely and then blew out the last supports. It actually began to rotate in the desired direction but hung up on stuff and headed for the library… Ouch!

I suspect it will turn out that the door frames at ground level stood up too well. The demolition guys should have used a bit more explosive to wreck those. Steel is amazingly strong. That’s why it’s used around openings in concrete structures. This view from the opposite side shows two serious doors that may have held things up…

About Robert Pogson

I am a retired teacher in Canada. I taught in the subject areas where I have worked for almost forty years: maths, physics, chemistry and computers. I love hunting, fishing, picking berries and mushrooms, too.

    Naturally you have availed yourself of the extensive demolition engineering literature to prove me wrong, Robert.

    God forbid that you just gave up silently, without admitting that you are a total know-nothing wazzock.

    You sure this wasn’t Donald Trump’s fault? What you “suspect” is of no relevance, Robert. Demolition engineers don’t generally concern themselves with the strength/stress CSI at ground level, because that’s not actually how they design the operation. It’s meant to be an “implosion,” not some loony “rotating round the steel supports” drivel.

    The demolition guys should have used a bit more explosive to wreck those.

    Another misconception, although a common one. You don’t “use more explosive” to remediate an issue; you just do a proper structural engineering job and look at the static model. You weaken the load-bearing elements (you don’t just blow them up, which is what we call an “instantaneous” force and apart from the inherent risk of misdirection is no goddamn use to anybody). And you do this from the top down. Gravity is your friend!

    This, btw, is the perfect OP for some lunatic 9/11 conspiracist (not you, Robert, obviously: ram springs to mind) to chime in on. I’m rather looking forwards to that.
