DISNFO: Hollow Towers Concrete Core
DISNFO CLAIM: The Towers were Hollow and had a Concrete Core
There are a few people that claim that the towers were hollow structures, made out of concrete or were even “missing floors”.
The Core Structure Of The World Trade Center Towers Was A Steel Reinforced, Cast Concrete, Tubular Core
Some people even claim there were no floors in the Towers at all.
9/11: Introducing the No Floors Theory
REBUTTAL TO HOLLOW CLAIM
This picture was taken near the end of Construction before tenants had moved in. The sun also plays a part as to why we see the light shining through.
If you look at this picture from the newyorker website. You will see that this picture was taken in 1972.

You can see from the crane on top of the South Tower and the smaller antenna on top of the North tower that construction had not been completed yet.
“The North Tower (1) was completed in December 1972 and the South Tower (2) was finished in July 1973.”
“The first tenants moved into the North Tower in December 1970; the South Tower accepted tenants in January 1972. When the World Trade Center twin towers were completed, the total costs to the Port Authority had reached $900 million. The ribbon cutting ceremony was on April 4, 1973.”
Typical Floor layout in the WTC
“The towers were designed as “tube in tube” structures, which provided tenants with open floor plans uninterrupted by columns or walls. Numerous, closely spaced perimeter columns provided much of the strength to the structure, along with gravity load shared with the steel box columns of the core. Above the tenth floor, there were 59 perimeter columns along each face of the building, and there were 47 heavier columns in the core. All of the elevators and stairwells were located in the core, leaving a large column-free space between the perimeter that was bridged by prefabricated floor trusses.”
Here are some examples of what appears to be the Sun shining through other buildings….
DISINFO: THE WTC CORE WAS MADE OF CONCRETE
The concrete core of the WTC
Even the BBC published an article two days after 9/11 saying the core was reinforced concrete.
How the World Trade Center fell
REBUTTAL TO CONCRETE CORE
Let’s hear from the people that designed them. They all say a steel core.
“Yamasaki and engineers John Skilling and Les Robertson worked closely, and the relationship between the towers’ design and structure was clear. Faced with the difficulties of building to unprecedented heights, the engineers employed an innovative structural model: a rigid “hollow tube” of closely spaced steel columns with floor trusses extended across to a central core. The columns, finished with a silver-colored aluminum alloy, were 18 3/4″ wide and set only 22″ apart, making the towers appear from afar to have no windows at all.”
The Center core was 87 by 135 feet (27 by 41m) and contained 47 steel columns running from the bedrock to the top of each tower. (NIST)
“Total center core size was 87 by 135 feet and contained 47 steel box columns (14 x 35” or 22 x 53”) running from the bedrock to the top of each tower. The lower cores steel was 4″ inches thick and it gradually decreased to 3/4″ at the top.”
Perimeter Columns: Each tower had 236 Steel perimeter box columns (14 x 14”) spaced 39” apart and joined together with steel spandrels.”
This is not a concrete box column.
DISINFO: “HOLLOW STEEL SHAFT”
Some people may even use the testimony made by John Farmer (9/11 Commissioner). But they fail to mention that John Farmer called the 9/11 Commission a “Half Baked Farce”.
“The outside of each tower was covered by a frame of 14-inch-wide steel columns; the centers of the steel columns were 40 inches apart. These exterior walls bore the majority of the weight of the building. “The interior core of the buildings was a hollow steel shaft, in which elevators and stairwells were grouped.” John Farmer (May 18, 2004 hearing)
“the interior core of the buildings was a Hollow steel shaft in which elevators and stairwells were grouped.” – John Farmer (9/11 Commission hearing #13, May 18th, 2004)
Exposing One Of The 9/11 Commission’s Blatant Lies
FEMA lead investigator Corley says WTC1 CORE initiation at 35:40 – unlike the NIST sagging truss theory – yet fails to explain exactly what caused the core failure.
“…because in scale, the perimeter columns were as thin and as flimsy as a sheet of paper….. which makes them very vulnerable to buckling….we can illustrate buckling with a piece of pasta…. and with very little pressure on the end, I can get this to buckle.” @19:40
@19:16 “Instead of heavy columns breaking up the interior, the Towers were essentially hollow tubes….like bamboo.”
REBUTTAL TO “HOLLOW STEEL SHAFT”
The Towers were not made of thin paper, bamboo or spaghetti. Discovery Channel is denying the massive center core and its strength.
WTC Complex: Over 350,000 Tons of steel (FEMA)
Center Core: 87 by 135 feet (27 by 41m) and contained 47 steel columns running from the bedrock to the top of each tower.
“Establishing the true nature of the core structures is of great importance given that the most widely read document on the World Trade Center attack — the 9/11 Commission Report — denies their very existence, claiming the towers’ cores were “hollow steel shaft[s]:”
CONCLUSION: DISINFO, MISLEADING, AND SERIOUSLY FLAWED INVESTIGATIVE JOURNALISM
