So go ahead and tell a building inspector that you are only going to use steel that is rated at half the strength that the codes call for. Or explain to a potential buyer of a high rise thet they shouldn't worry because half the strength called for will do the job just fine..... Give me a break.
Now why do you act as if it was only jet fuel that was burning? There was everything from carpeting to plastics and god only knows what in those offices that was burning, and the more fuel you add the hotter the fire. The jet fuel was only the catalyst that started the fires.
That's just stinkin thinkin there Ollie Ollie All come free. The fact is that half rated steel was not being used. My statement was to show that the steel even at half strength was totally sufficient in strength to withstand the forces safely. Ya there were other combustibles but as I stated earlier the space was well ventilated with all the broken windows so there was no way the heat could be concentrated enough and even if there were pockets of heat the temps could not get high enough to degrade the steel. There is a big difference in "room temp" and "direct flame contact".
I frequently work with a forge..a small blast furnace. It takes a long time and many thousands of degrees of direct contact with gas flame to get steel hot enough to make it . Divecon and fizzled out are blowhards with no knowledge of the characteristics of the materials we are disscussing.
They are just pubescent assholes that can't stand to be wrong and will go on endlessly calling names and throwing fits to try to win a losing arguement.
I do not have a conspiracy theory. All I can say for sure is what DID NOT HAPPEN. The steel did not fail because of the airplanes or the ensuing fires.. I realise that the crashes looked real impressive and destructive. If they did not knock the buildings down on impact then they were not the cause of the collapse.
