The image showing the
concrete core wall at its base is conclusive when no steel core columns are seen.
It is preposterous to atempt to conduct an argument sach as you do with NO EVIDENCE while images showing
concrete and no steel core columns are present.
Again, I'm ignoring the algoxy links. I've seen that picture lots of times and it shows no concrete core. That picture is so grainy it's difficult to determine just what it shows.
Once again, I realize that changing the subject is your tactic and the fact that to get to some floors you had to go to the 42nd first and change elevators escapes your capacity to identify the needed mechanical relationships and structural loading into the tower and the elevator systems.
Christophera, you keep getting the FLOOR NUMBERS wrong when talking about the sky lobby and mechanical floors--even after Bell posted the correct ones here in this thread! If you can't even get that basic information right, how can we trust anything else you say?
I have never mentioned the damping system. Know nothing about it.
Well, one of your earlier posts said:
The weight of a tower needs to be below the middle for greater stability. Putting the heavy elevator motors and AC machinery on the 43rd was that principle. That floor had structural cast concrete walls and floors out to the perimeter walls holding the shear panels of the walls in dimension, no flex, while mounting all the heavy elevator machinery, in postion in the core. That is the reason that some elevators only went halfway. (bolding mine)
The comment about
stability implied to me you were concerned about the tower's stability and thus, by extension, the damping system. Since you say you don't know anything about the damping system, I withdraw my suggestion that you believe the elevators and mechanical rooms were put where they were to aid in that.
You did, however, imply that the mechanical rooms were located "halfway up" (see bolding above) to keep their weight in the lower half of the building. But a little research turned up a couple of facts:
1. There were no mechanical rooms on 54, 55, or 56, which would have been "halfway";
2. There were not one but
two sets of floors dedicated to mechanical equipment above the halfway mark. So that kinda blows your theory about them needing to be in the lower half of the building to maintain stability.
Stop trying to change the subject and show some images of the supposed steel core column or give up.
The reason I'm "switching topics" is to show that you have such a poor grasp of even basic facts such as of the layout of WTC 1 and 2 that you're nuking any credibility you may have on other stuff. It's like a kid trying to show me he knows advanced topographical geometry when he can't even accurately describe a square vs a rectangle vs a parallelogram.
