QUOTE (Paul @ Mar 4 2011, 09:40 AM)
Can you please show me these pictures where the ends of the columns appear to have been blasted? Can you provide any links plz?
And what do you mean by blasted? Do you mean explosively blasted? Also there was a picture on 911freeforums and i rember someone
pasted and showed me a picture back when i was a no planer dolt on 911movement.org run by killtown of a column where the ends of sort of box column where pointing outwards and i also saw a picture off a column on 911freeforums whick looked similar to the picture i had been show on 911movement.org and someone said even on 911freeforums as though it looks like the end of the columns has been blasted apart by explosives
kind of split apart i found these photo's very interesting and quiet compelling too bad the columns have been since recycled and sold for scrap
otherwise we would be able to test the suspect columns for explosive residue, if anyone knows these pictures i am talking about can please post
a link to pictures in question.
Cheers take care Paul S
These are all good questions on the PREPARATORY WEAKENING at WTC1 and WTC2.
I can't give you any links. I just have these three books.
The Hufstead book," Painful Questions" shows in Chapter 3, excellent drawings of the exterior column prefab construction and connections.
The John Botte book, "Aftermath, Unseen 9/11 photos by a NYC Cop", is essential with many photos of the exterior column ends in question.
FEMA "World Trade Center-Building Performance Study" FEMA 403 September 2002
In the WTC1 and WTC2 buildings, the 47 core column construction would be a free-standing building if there were no floor joists and no exterior columns. Similarly, the 236 column exterior frame constitutes a separate structure, free-standing, if there were no floor joists and no core structure. So the demolition is perhaps best understood by approaching it as the collapse of two separate structures in one building. Preparation is different for each structure and the detonation placement and sequence is different for each structure, with the perimeter collapse hiding the interior collapse.
My view is that there is evidence of unbolting of some of the end connections on the exterior prefab column sections. (For Island Pilot) There is no necessity to remove any ceiling panels to access these 6 bolt (lower floors) or 4 bolt (upper floor) connections. They are easy access at about 60 inches off the floor. Two-thirds of the staggered columns were continuous at each floor. Punch a hole in the 5/8" drywall and there you are. Easy access to the bolts as there are cutouts in the column wall facing the inside of the building.
From an examination of the photos in "Aftermath" with a magnifying glass, I don't see any "witness marks" of explosive charges or any slag which might adhere to the end plates if an oxy-acetylene cutting torch was used to cut the head off a bolt. My main point here is that if these joints had all the bolts in place at the time of collapse, we should see distortion in the end plates as the tension on the bolts tries to pull the head of the bolt and the hexnut through the plate. The bolts were 7/8"diameter and 120 thousand PSI tensile strength and the thickness of the endplates varied from the bottom to the top of the Tower. These connections should fail at the weld of the plate to the column if all 4 bolts are intact. In fact, a picture in "Aftermath" shows one such separation.
This topic is addressed in the FEMA " World Trade Center-Building Performance Study" Appendix B Structural Steel and Steel Connections. Page B-8. It is essential reading for those seriously interested in the subject. The analysis there does not stand up to close scrutiny along with so many other things in the Study. (I can give further infomation on this.)
I'll close with an anectdote. In one of the early 9/11 DVDs, Paul Rodriquez, the Stairwell Maintenance Supervisor, reported hearing what sounded like a jackhammer on a floor which he knew was unoccupied by tenants and he had the key but was afraid to go in; and he did not enter. The sound of a large air rachet wrench might be what he heard. He reported hearing something heavy rolling across the floor. Air compressor?
