Core Box Columns: Types of Damage

Core Box Columns: Types of Damage

In order to appreciate the information captured in a bent or damaged piece of thick metal, one would have to understand just how many core box column sections seen in the WTC rubble appeared straight and in a miraculously undamaged condition.

This is a difficult point to emphasize to the reader because there is no one individual picture I can show to help you understand. You would need to look through many pictures to appreciate just how high a percentage of core box beam sections had no descernible damage, even after all the abuse to which they were subject.


I offer 4 separate albums of pictures that focus on the regions where core columns were plentiful. Please see the The North Tower Debris Field, The South Tower Debris Field, Debris in the Plaza Area and General Photos of the Debris photo albums in our photo archives.

The core box columns clearly had a phenomenal resiliency to being bent, twisted or even dented, even after all the abuse to which they were subject during the progressive collapse, or demolitions.

That is why the photos I show in this essay originally grabbed my attention.


The large, large majority of core box columns seen in the rubble were straight, showed no denting along their entire lengths and were severed at each end along their welds.

The columns shown in this essay are the rare exceptions

Every one of the following examples show box columns that appear as if they received at least one forceful blow from one of it’s sides, at or near the weld connection.
a

Examples 1 and 2


The upper beam seems to have been hit with a large force coming on sideways at the place marked B, at or near it’s corner.



Notice the darkened, rusted color around point B. The visible end of
this column seems to be broken at its original weld line, as you can tell by the small but distinct markings around it’s end.

Point B is about 4 feet from the original weld.


The beam marked A has some distinct curvature at it’s end. It is very important that we understand these distinctive features at the end of this beam section because, as you will see, this bending and ripping pattern is at the ends of a number of box beams found in the debris.


In the photos below we see a unique type of destruction to the end of a column. I've never seen another example like this.
a

a

Example 3

This is a strange example of a box beam where it seems as if the steel sides were actually blown outwards.

I’m guessing that the steel is about 1 to 2 inches thick.

There is obviously a big gouge taken out of the corner and the metal around that gouge appears to be pushed outwards.

Notice how the dimensions a, b and c all appear to be different. It seems that a>b>c.

I have found no other example of all sides of a box beam being pushed outwards. There are no access holes that I know of along the length of a column or any way I know to place a bomb inside a box column.



In the photos below, please remember that deformations in the core box columns were the exception, even after the extreme conditions to which they were subject. The end of this column seems as if it was laterally pushed, the weld breaking only after extreme resistance (hence the distortion).

Example 4

The above photos are of the same box beam taken from 3 different angles.

Here we have the same rip and bend pattern at the the box column section.

There is clear bending on the wide top side of the beam, too. And the entire beam section is bent, not just it’s end.

The beam seems to have received a powerful blow on it's long side side, The visible end seemed to “rip” away from the piece above. The “rip” is right where the original weld was.



The beam seems to have received a strong blow about 10 feet from it’s end, but we would need to see the whole beam to make a better guess.


Below we see one of many models which could explain such damage patterns.
a

One possibility

As shown in this illustration, an attack on the long side of the rectangular cross-section a few feet from the weld would explain quite a few of the photographs in this essay.

Thanks to "Moslem Engineer" for the 2 graphics.

Example 5

I judge the column shown above to be made of 2+ inch thick steel, which would place it lower in one of the towers.

Extreme force must have been applied. It is very rare to see a column of this thickness of steel to be deformed within the rubble.

a

Example 6

In the photo above we can see, yet again, the steel along one long end of a box column bent outward.

The column was split along the weld, and pushed to one side?


Below we see a column made with very thick metal showing 2 different types of deformations.
a

At one end we see a concave inward bending along the long sides of the end of the beam.

The beam, like most all the others, was split across it's original weld.

This metal is very thick. This type of inward bending is very rare among box columns of this thickness and requires extreme inward force.

We see the other end of the column below.
a

Example 7



The steel is between 2 to 3 inches thick. It is rare to see the metal actually split along the length of a column like this. The very ends of this column are split across the original welds like most all the others. But the metal break closest to the viewer is is right through the original casting on 3 of the 4 sides of column.

That metal is "ripped".



In the example below the metal seems to be....well.....blown away at the weld.
a

a

Example 8

The rectangular cross-sectional proportions suggest this is column is 601, 608, 901, or 908.

There is obvious metal distortion at the top end, right where we would expect a weld to be.
a

Examples 10 and 11

In box 1 we can see a bend with some metal actually ripped off of a corner. The end of the column is right where we would expect a weld to be.

Box 2 shows yet another massive horizontal blow at the corner of a beam.
a

a

Examples 12 and 13

There is an interesting inward indentation at the end of the beam in the lower picture.

In the upper picture 3 of the 4 sides of the end of the column appear cleanly broken along the original weld surfaces. But along the remaining side, the weld itself seemed to hold. The metal actually ripped just above the weld.



In our last cited example below we see metal distortion quite consistent with a sharp blow delivered laterally to the long side of the column just above the weld. The column was severed along mostly along the original weld connection with a piece of metal ripped away from the applied force.


a

Example 14


This column is probably to 607 or 902 to 907, or 701, 801, 708 or 807.

It is severed right along the original weld surface, like basically all of the examples mentioned.

There is obviously a big gouge taken out of the corner and the metal around that gouge appears to be pushed outwards.

A Note To Other People Looking For Evidence

All of the photos shown in this essay were gathered in a 3 week period in May, 2007. All of these images were taken from photos that have been publicly available for quite a while.

Since that three week period the photo albums on this web site have doubled or tripled in size. I have not scanned these newer photos for evidence of core box column distortion patterns and apparent bomb damage. This means there are probably many more examples available in the following 4 photo albums:

The North Tower Debris Field
The South Tower Debris Field
Debris in the Plaza Area
General Photos of the Debris

Anyone who wishes could look through these albums for more evidence of metallic distortion at the ends of core box columns consistent with bomb damage along the weld surfaces at each end of the columns. All you need is an image viewer with a zoom feature. You will want to zoom in as much as possible to see as many detailed features as the resolution of the photo will allow.

All photos from these albums can be accessed and downloaded in batches from the following link:

http://www.sharpprintinginc.com/911_old/Photo_archives/


Dear reader, please don't assume that the best evidence contained within these photos has been extracted and analyzed. I can assure you that they were not.

Please do not assume that "qualified professionals" or "experts" have already gone over these photos. This work has to be done by people like you and me.
