This is for you cackling cat:
As usual, you read something, didn't understand it and came on Terb pretending to be an expert: "I studied structural engineering and took metallurgy courses for three semesters".
The experts have provided the answers and their peers have critiqued and agreed. I'm only pointing out the errors in YOUR post.There are too many variables and no previous events to compare the collapse of these buildings to. Experts far more qualified than guys on TERB can not give you an answer. So you can debate till you cackler gonads fall off and you will still not know what truly happened.
But your explanation was completely wrong. Since no steel support columns existed on each floor they could not have "weakened and buckled". The karate chop example in no way applies to how the floors failed and pancaked.Your explanation is another explanation of my explanation. Did you use to cheat in school and copy up other people work in your own words?
