I wasn't talking about the "beams" and floor trusses that supported the weight of
people and furnishings.
I was talking about the inner 47 steel "COLUMNS" that were the heart of the building.
They WERE designed to support ALL the weight above them or the building would
have never stood in the first place. That is my only concern as to the failure. The
floors were agreeably "flimsy" compared to the rest of the building.
The outer shell should have collapsed "in" from the pancaking of floors. Not blown
out from the building. For the "inner core" structure to have disintegrated seems
3 buildings fell yet they all had different characteristics of failure.
2 buildings were struck by a plane, yet not on the same floor. Not the same columns.
1 building failed with a whole different set of circumstances. Would you agree?
The pancaking of the floors is very feasible, but every single support bolt had to shear
at the exact same second or it would not have been symmetrical and the building would
have collapsed lopsided..IMHO....possibly stopping some of the floors.
They didn't use the same grade shear bolts on floor 78 as they did on floor 98. That is
why the design load had to support the upper floor above it.
