Again, every steel framed high-rise that's ever caught fire matches the design of the towers far better than your big bag of nothing. There's no point in me listing names of the many steel framed high-rises which have caught fir unless you can name a model that purports to prove fire brought down the towers to compete with.
Name the ones you've looked at.
You can't, can you? You're going to have to frenetically Google and Wiki in the hope you can cobble together a list of some description, aren't you?
FACT: Testing shows that steel is susceptible to failure under normal fire loadings.
FACT: Steel structures have suffered substantial failure due to normal fire loadings.
FACT: WTC 1 and 2 employed steel structures and suffered from fires across entire foorplates on 9/11.
What you're trying to do - and pretty obviously, I have to say - is argue that because no building has suffered from 100% collapse then there is something suspiscious. This is, however, an appeal to perfection and I am willing to wager that if we show you a picture of a complete collapse then you'll move the goalposts to "complete collapse of a tall structure" and so on, ad infinitum.
But meanwhile, name the structures you looked at when considering ire performance. Let's have a list.
What are you suggesting in those 100 years of experiments would best supports the notion that impact damage and fires could bring down buildings anywhere near as quickly and completely as the towers came down.
Argument from personal incredulity noted. Do you have any facts to bring, or just more speculation?
