  • hey everyone, devil`s advocate here (and a civil engineer).

    the critical temperature in question is not the melting point. at lower temperatures, steel behaves elastically, meaning it regains its initial state. then it starts to behave elastoplastically, which means it almost regains its initial state with no critical damage. then it behaves plastically, which means it deforms and cant get back its initial state and leads to structural failure, gradually. eurocode 3 covers building fires up to 800°C if im not mistaken, meaning steel doesnt lose its structural capacity up to that range. knowing how these codes are written, i bet it wouldnt turn into slush at 801°C.

    additionally saying that “the entire strength of the structure was on the outer edge” is plain wrong. nobody even would consider to design a building like that, and i know for a fact that the core of this specific building was exceptionally and unnecesarily built strong.

    i have been having this inner conflict with myself for decades. these two building fell after a plane hit them (and another without a plane impact). but i cannot accept that they caused the collapse, my professional integrity does not let me.





  • i have a logitech mx ergo and i love it. i had doubts about getting used to it, because most of my work consists of cad and 3d files, but it took like a day to get used to it. now i’m more comfortable using that than any other mice. i have a thinkpad at home and i love the trackpoint, too. maybe that’s the gateway pointing device :)
