Such a ridiculous comment.
The core columns were designed to hold up 3 times it's weight.
The outer columns were designed to hold up 5 times it's weight.
The columns were holding up all that weight for decades.
If all the floors pancaked, the core columns would have remained standing.
According to your buddy the piggy they only had 1/4' filet welds.
The floor beams should have ripped away from the core columns.
Perhaps the piggy has a formula for that one.
Do try to pay more attention. Besides, your opinions have already proven to be false.
