Frank Demartini says in the video-That the towers were designed that it could take a hit from an airliner.That its like an intense grid comparable to the screen netting on your door where a if you puncture the screen netting with a pencil it does absolutely nothing to the netting.That the towers were OVERDESIGNED to take a hit from an airliner so much that he went on to say it could take MULTIPLE hits from airliners and still remain standing.
Sounds like they designed it for the IMPACT not the subsequent fires. Funny how Frank didn't say how the screen would stand up after the pencil went through and if the screen caught fire.
I ALREADY addressed that earlier howe they anticipated the fires but since you only read only PARTS of posts,its only natural you missed that.
Nope. Didn't miss that. Everything you have provided as evidence suggests IMPACT or the force of the impact. Can you show me any quote anywhere that says the engineers did studies of the affect of fires and heat on BARE steel columns? Columns without fireproofing? Do you think they had taken into account the fireproofing becoming dislodged and the effects of fire and heat on those bare areas?
All they say about fire is that there would be a great loss of life. Why is it that engineers nowadays can provide calculations and evidence of fires weakening the strength of steel columns/beams to a point that the steel will fail but Robertson somehow missed that? Maybe miscalculated? Can you explain? Did the laws of fire and it's affect on steel somehow change from then 'til now?
Tell you what. You can make this easy on yourself. Go to Leslie Robertson's LERA site and find the contact link for Sawteen See. Send them an email asking if the did studies for the affects of fire on the steel columns. See what they say.
