So, you say that the temps from the combustible materials inside the building were hot enough to cause this expansion and in such uniformity, that the building collapsed in a straight down symmetrical fashion?
*sigh*
As has already been explained to you numerous times, components in a building design are calculated to work TOGETHER to support loads. When you start to fail components such as connections that were sheared due to thermal expansion, you start to take away from the design as a whole. When components start to fail, the load they helped support must be transfered elsewhere and thus put additional load on the remaining structure. That structure can only handle a certain amount until it fails completely.
You keep using the term symmetrical. That collapse was FAR from symmetrical as the east penthouse collapse followed by the west side. THEN the perimeter collapsed.
Let's discuss something. When the east penthouse collapsed and then the west side, what was left?
Here is the unedited collapse of the WTC 7 building..do you see the big main part of the building, AKA as the ENTIRE BUILDING collapsing in a straight down manner that produced 2.25 seconds of freefall?

You are doing mental gymnastics to overlook this fact...all the BS about one particular support beam or trusses you say actually caused this? With only sporadic office fires, and it didn't show signs of deformation that sporadic fires and temps, in a few areas of the building had?
NISTs explanation is crazy, we would expect to see some partial collapsing and deformation..but in all 3 buildings we witnessed straight down global collapses. NIST theory and your adherence to it is absolutely fucking nuts.
Another question for you. Here is Chandler's quote from the Remeber Building 7 site.
Remember Building 7 | Stand with the 9-11 families demanding a NEW Building 7 investigation - Free Fall Collapse
Pay real close attention now.
Chandler said:The collapse we see cannot be due to a column failure, or a few column failures, or a sequence of column failures. All 24 interior columns and 58 perimeter columns had to have been removed over the span of 8 floors low in the building simultaneously to within a small fraction of a second, and in such a way that the top half of the building remains intact and uncrumpled.
Did the bolded and enlarged text in Chandler's above quote happen in that video you just posted? Did all 24 interior and all 58 columns get removed at the same time? Yes or no.
