Some Misunderstandings Related to WTC Collapse Analysis

[Tony Szamboti]

Oops, time for another reality check here. See http://www.youtube.com/watch?v=NiHeCjZlkr8

The North Tower never decelerates and a natural collapse would have to. This is something Jeffrey seems to get tongue tied explaining.

He also forgets to tell you that his ROOSD (Runaway Outer Office Space Destruction or more commonly known as pancaking) requires a significant number of floors to be broken loose, so there needs to be column destruction during the first several stories of the collapse before ROOSD can even start.

By saying ROOSD explains everything Jeffrey is trying to tell you that a horse isn't required to pull the cart and that it magically moves on its own.

P.S. the only individuals who have ever called me a liar were anonymous individuals with wacky ideas and postulations on the JREF Forum. It is a disgrace that you would even say that here. Neither you or anyone on the JREF Forum has ever shown me to be in error, you only try to say you have. So it is also disgraceful for you to talk as though you and these anonymous individuals have. Your discourse here reminds me of that of a teenager telling fibs about things he has done to impress people.

ROOSD explains the destruction once the threshold mass, in this case perhaps 5 floor masses crashed onto an undamaged floor and the rest was wash rinse and repeat to the ground.

As I have stated for years now the issue is how did those top sections of the towers...12 -15 in 1WTC and about 30 in 2WTC break apart and break free. We know the plane damage severed several and weakened/damaged other columns. The damage as not symmetrical w/ respect to the CG of the upper sections in both cases. And neither was the weakening from heat which came from unfought fires on unprotected steel (assumed) which finally drove the capacity of the remaining columns below their imposed loads. The asymmetry of the remaining support with respect to the CG of the upper portions induced enough rotation such that the unrestrained column ends which were 4' above the slab level slipped out of alignment and facilitated an almost unimpeded descent delivering the threshold ROOSD mass. The pre release movements indicate in no uncertain terms that there was load redistribution underway inside the core (antenna drop)

There are a list of I believe 42 errors which have been raised about your work.

So ROOSD needs about five floors to have collapsed first before it can get going. So what needs to happen before that is the columns need to be destroyed to let the floor masses go, and in any naturally caused collapse of the columns there would be deceleration, which is not observed.

The plane impact on the North Tower was on the north face, yet the collapse initiated favoring the south face. That sort of knocks your theory, about the asymmetric impact damage having anything to do with the collapse of that building, out of the box.

We also know that the number of damaged/severed columns was only about 15% and that the reserve strength of the columns in those buildings was quite large. The perimeter columns only had 20% of their capacity utilized and the core columns about 33%, for gravity loads, which was all that was on them on Sept. 11, 2001.

Your claim of 42 errors in my work is ludicrous.
