1. I use the term, "wheatchex" to refer to the prefabricated sets of three outer columns, three stories tall,

connected with spandrel plates as shown in Figure 1.

If the WTC was destroyed by a gravity collapse, what would engineers expect to see?

Figure 4. Loading Figure 5. Cross-section diagram of floor truss connections.

2. Either the truss supports hold or they don't. If they don't hold and there is pancaking of the floors, there

will not be column failure. If the floors pancake down, the columns will no longer be carrying a significant

load. If the truss supports hold and there is no pancaking ,and if the columns are overloaded and/or

tremendously weakened, there may be column buckling. Consider the case of buckling.

than it does perimeter columns of the WTC (wheatchex).

5. If the WTC "collapsed" from overload, columns would exhibit buckling failure. However, there is a lack

of buckled columns in the "rubble pile." For that matter, there is also a lack of a significant rubble pile.

No matter what hypothetical fire event is posited, the following cannot explain the "rolledup carpets."

6. A gravity collapse with or without heat won't cause this type of failure.

• Bombs won't cause this type of failure.

• A nuclear explosive won't cause this type of failure.

• Cutting torches won't cause this type of failure.

• Thermite can't cause this type of failure.

buckling, easily identified by kinks in the

Figure 69. Buckling occurs near the midpoint of an unsupported

length in a zone where the material is weakest. If buckling

initiates at a point, it cannot deform a straight beam into a smooth

arc of greater than a 180° bend.
