Has Anyone Seen A Realistice Explanation For Free Fall Of The Towers?

That must be WTC 2, and the concrete core is there. WTC 2 had 2 hallways in each direction whereas WTC only had 1 hallway in one direction on every other floor.

Wrong, again, Chris. As I always ask and you never answer, please provide a hallway diagram that fits it the photos. Your diagram will need to be of multiple MOVING hallways on each floor. Remember, these are stills from VIDEO. The "hallways" move when the camera does! I think you've had enough time to provide that diagram. What? You don't remember that? Allow me to refresh your memory (This is for the benefit of Chris and newcomers. My apologies to others):

Notice that only 7 floors show light through. I know that only 7 floors weer allowed over the top of the concrete core.

No, Chris, the top photo shows 18 floors with light coming through at many spots on each floor. Unless you're claiming the concrete core was constructed starting at the top. Is that what you're claiming, Chris? Please respond.

Since you post in support of no concrete as the core, but never adequately support the steel core columns, it is beginning to look as though you suppor tno core what so ever, an AIR CORE.
Click to expand...
No, Chris, I've posted the core photos about a dozen times on this thread. Remember this one?

879044e76299ec2b2.jpg

Say, Chris? Why is it that you ask to see a photo of the core columns (as above) "above ground level?" As you know, there are many photos of the core columns from below ground level, taken during construction and during cleanup. What do you have against those photos? And why isn't your concrete core there? Are you claiming that the concrete core was only in the middle of the buildings, not at the bottom and top? That sure would be strange, wouldn't it, Chris?

You claim that a tower of concrete, thousands of tons worth reaching a height of about 700 feet, stood after the south tower collapse. Where is the photographic, audio, seismic or eyewitness accounts of those millions of pounds of concrete crashing down from 700 feet?

You've been asked these questions many times. You refuse to answer them. Again, I'm just pointing this out for the newcomers.

Now I see that you're emailing prominent "truthers" about this pressing issue and pointing them to two websites that tell the whole story of the concrete core. Lo and behold! They're your websites! Good luck with that program.

Please provide your diagram of the multiple moving hallways now. You've had a few months to put it together.

Finally, Chris, what is the recipe for Invisicrete?

The floors were attached to the interior box columns and perimeter box columns by the floor beams fastened to the columns. The Concrete Core brought rigidity and stability to the steel structure as it advanced.

So they had 7 floors of un-rigid and unstable steel structure until the concrete could catch up with them? Bwahahaha. No building inspector in the world would allow that.

Also the floor trusses were much tighter spacing than your supposed box columns. What were the trusses between columns attached too?

PS. people are confusing the design of the high speed elevator shaft which had a drywall board construction with the main Central core, which was designed as a movement arrester with out it the building would have made people sea sick from oscillation in the wind.

In most buildings with a central core this is true, however the World Trade Center was specifically designed to take lateral loads on the face of the building and NOT transfer those loads to the core. That is why they installed the visco-elastic dampers in the floor joists, to keep wind load from transferring to the core.

This was to reduce the number of columns needed in the core and increase rentable space. Also if you'll check the floor plans in the NIST report you'll see they called for covering the core in drywall (for aesthetic reasons, they were going to leave the columns exposed.)
 
Mr. Brown, why do you do what you do? What is to be gained by lies, insults, innuendo, prevarication, and other sundry tactics? Are you proud of your methods?

Why, Mr. Brown? Why?

Is it possible to nominate a body of work for the TLA? Regnad Kcin's kindly Doctor Marcus Welby in this string is bordering on priceless! (Although the veneer does seem to be slipping in this last one.)
 
What, All Those Posts And No Evidence Of Steel Core Columns?

Hmmm, ..... you distort what I said. The steel would flex with the loads of the kangaroo cranes.



The trusses were attached to floor beams and they can be seen here and
below the spire
 
Christophera, at least give yourself an avatar of a cute chick for god's sakes!

Childlike Empress got that right away.

The kangroo cranes were not attached to building steel. they had their own jacks. Makes it hard to dismantle if you attach them to building steel.

And flexing steel is un-rigid and unstable (hence the word "flex"). You don't attach floors to flexing steel, you attach them rigidly supported steel or (in other buildings) rigidly supported concrete. Your entire proposed building construction phasing is wrong, the building would've fallen over before they began.
 
Crane Platform Frequently Mistaken For DIAG. Braced Core Columns

The kangaroo cranes had their own platform, the heavily trussed assembly that fit inside the core and attached to the interio box columns. The entire platform and individual cranes could be jacked up and down.

Note there are no Massive Columns inside the core area. the steel that is there is support for elevator guide rails.

Crane platform and interior box columns ringing the core "Massive columns"

here an interior box column is seen outside the concrete core or the concrete shear wall to left of interior box column, the "spire".

Christophera, your mental problems are sad. Please seek professional help.

By the way, have you finished that diagram of the multiple moving diagonal hallways that run through each floor of your concrete core? You promised me that months ago. Please provide it now.

You didn't address the questions in this post. Please do so now. http://www.internationalskeptics.com/forums/showpost.php?p=1858464&postcount=2481

My diagram of hallways and interior walls of the WTC 1 steel reinforced concrete core stays as it is and is as finished as it will be.

Please provide some evidence of the steel core columns that is not mistinterpretations of construction photos or WYC report lies. Something like images from the demoliton that do not lie.

If there was a hefty concrete core within the WTC in addition to all those steel core columns, how was this landing gear able to go through straight through the centre of WTC1 and take out a perimeter column tree on the south side of the building?
