It appears quite obvious that my opposition has no independently verified evidence of the steel core columns whereas I do have such evidence supporting the existence of the concrete core.
Clearly, Robertson is verified by Oxford, verifying Domel verified by the image of WTC 2 core, verifying the top of WTC 2 core falling onto WTC 3, the WTC 1 rebar, just after the WTC 1 west core wall is seen in an end view, then, the WTC 1 east shear wall toppling, consistent with interior box columns silhouetted on WTC 1 north core wall, consistent with ground zero showing the WTC 1 north concrete core base wall, 12 foot thick, all supported as clarification of the many confused statements that do mention concrete in the core including the latest revised NIST contracted analysis of free fall by Bazant et. al 6/21/2007, which actually provides an equivalent amount of high explosives needed to create the rate of fall they are attempting to justify with physics. It doesn't work, but at least they won't go down in history as totally supporting the deceptions.
So all they can do is try and change the subject.
clearly you are a fucking moron. (nice car, by the way).
not only do you lie and claim ronertson said something he never said, then you misrepresent oxford, but the two references you use contradict each other!! what a fucking idiot!!!!!
![lol :lol: :lol:](/styles/smilies/lol.gif)
oxford says "steel and concrete" while you lie and claim robertson says "concrete".
well guess what, deadbeat. ONE OF THEM MUST BE WRONG. its either concrete or its steel and concrete. they cant both be right.
and here is a very small portion of the evidence that proves the WTC had a STEEL 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. "
Newsweek. Newsweek.com
"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"
Time Magazine.TIME.com
"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."
Berkeley 04.17.2002 - World Trade Center remembered
"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."
