I have Chuck's graphics and I challenge Skilling to prove that the safety factor of cc501 is more than 1.5. This is a matter of high school math...
The total weight of column 501 from the ground floor to the roof was 1,262,990 pounds
The cross sectional area was 573.5 sq in at floor 1
The capacity for a standard A36 steel would be 20,646,000 pounds
Estimated load on CC501 was 12,000,000 pounds (more precision to follow)
The perimeter core columns supported 43.1% of the OOS floor load
The facade columns supported 56.9% of the OOS loads
If cc501 had a safety factor of 20 and it was from A36 steel then the loads would have it be 1/20 of 20,646,000 pounds (its actual weight) or 1,032,300 pounds. The columns ITSELF weighed 1,262,990 pounds.
Jim you and you friend Chuck are in way over your head when it comes to engineering. You are a parrot repeating things you heard and likely incorrectly and have no comprehension of them whatsoever.
Jim you really need to get a bit more serious and stop presenting yourself as an expert.
