Because more than 50% of the load bearing beams were not sheered off. You know the outside cladding of the twin towers? Those are the actual load bearing steel beams and carried 60% of the load. The only other load bearing beams were in the center around the central shaft and they carried 40% of the load. The planes sheard off most of one side a significan chunk of the other and who knows how many beams from the middle.
The buildings were designed in a donut shape for an open floor plan concept.
In addition to that, while steel melts at 1500c it actually structurally weakens at about 800c. There are videos on line of people taking load bearing steel beams putting them over a wood fire for about 12 hours and they lose all of their structural integrity under their own weights. If they have huge amounts of concrete on top of them, you only need to weaken them enough. Wood and office stuff burns at about 800c to 1000c as its mostly cellulose and petroleum products.
Take this building and destroy 50% of the load bearing steel beams and let's see what happens.
OK so first off we are talking about tower seven, which was never hit by a plane.
But say we were talking about the 2 main towers, so the structure on one side was sheared off, and then it support steel doesn’t melt but it weakens (and then leans to one side) at 800c. yet it fell straight down demolition style? And you’re forgetting that the world trade towers were extremely over built. The beams and support structure were not carrying anything near their maximum load.They were also meant to withstand a Boeing 757 hitting them without any problem whatsoever
I'm not talking about tower 7. That was a clear demolition, you can see the squibs going off. I am only talking about the twin towers.
I know, but you replied to my comment, and my comment was about tower seven. But I answered what you said about the twin towers in my last reply
