All your subterfuge proves is you have no evidence of steel core columns in the core area and that you are working to support the secret methods of mass murder by ad hominum attack.
this is from the man that cant show ONE picture of the concrete core under construction or ONE quote from anyone that worked on the building claiming its a concrete core.

"For a combination of historical, cultural and economic reasons, tall, concrete-core buildings dedicated to office use are unusual in New York, where builders prefer the wallboard-enclosed cores with steel frames that Mr. Robertson pioneered in the trade center."

"Engineers are still debating whether the Twin Towers' unique structure should be credited for surviving the initial crashes, or blamed for collapsing in the subsequent fires, or both. But the point is that it was unique, utilizing closely spaced columns connected to a steel core by relatively lightweight floor trusses. "

"Each of the towers, more than 200 ft. wide on each side, contained a central steel core surrounded by open office space. Eighteen-inch steel tubes ran vertically along the outside, providing much of the support for the building"

"The twin towers were the first supertall buildings designed without any masonry. Worried that the intense air pressure created by the building's high speed elevators might buckle conventional shafts, engineers designed a solution using a drywall system fixed to the reinforced steel core. "

"Like many high-rises built in the 1960s, the Twin Towers were constructed with their weight distributed between a hollow steel core (containing services like elevators) and steel columns around the perimeter, maximizing open floor space. Many believe the older high-rise design, in which steel columns are often encased in concrete, is more fire resistant.
“A lot of people have told me, ‘You should have used more concrete in the structure,’” said Robertson. However, his chart plotting the strength of steel vs. concrete at various temperatures showed that at the incendiary levels that raged in the towers, the two materials become similarly weak."

"Yamasaki has switched from concrete, his favorite medium, to steel because of the sheer height of the towers, and instead of having the weight of the structure carried by the frame and the elevator core, the great steel columns of the exterior walls will support it."
