Merged Why WTC7 should not have collapsed

Try it yourself with a table with say 10 legs. Remove one leg and the table does not collapse. Try it with a table with only three legs and remove one leg. Nothing happens if you have secured the legs to the ground!

I'm curious whether you've scaled your experiment up to a table with a 47-story height.
 
Heiwa said:
As I understand it, primary structural part; vertical column 79 is assumed to fail and displaces downwards and connections of secondary structural parts to this column = horizontal beams are assumed to shear off. Not proven of course - it is just an assumption.

You forgot a rather important detail in NIST's analysis, that localized floor failures near the column left it free spanning up to 9 floors floor the 5th to the 14th floors. Where the failures did occur the floor members were already gone.

3D-beam structures with say 60 vertical columns as primary parts carrying the loads to the base and with horizontal beams as secondary parts with loads on them connected to the columns at regular intervals do not collapse, if you remove one column.

As per WTC 7's structural design everything above floor 5 was supported by three vertical trusses. Exterior load bearing members transferred loads to these trusses via cantilevered girders:

In other words that statement demonstrates that you haven't scrutinized the structural framing of WTC 7 much if at all.

Weak analogies are not valid here...

Heiwa; send that to NIST and post their answer please.

Heiwa do it! We need a laugh when they find someone with pure CT bias failed ideas! Throw in the kids on the bed stuff; skip the structures, you mess it up.

Heiwa, do it!

So you are telling me a 47 story skyscraper is similar to that of a table with ten legs...

For Godsake's will someone PLEASE put a rush on the FEMA death camps! The NWO has been taking way too long on that project.

Re your question ... yes.

BTW - when you removed one table leg, did global collapse follow?

What else do you worry about?
 
The table analogy is absurd. You are not talking about the same materials or forces.

Your arresting mechanism assumes only one action, thje collapse of the floors. You disregard the other floor slabs pushing against the vertical columns after the slabs on the other side have fallen. You have a lot of forces pushing unevenly in several directions. That was what Sunder repeated several times in the report, when he emphasized the asymetricality of the floors.
 
I've done my part. I submitted my comments on the possibilty that the sulphuric acid from the storage batteries caused the Swiss cheese steel.

How if we dropped a cinderblock from two miles.
 
So to sum up Heiwa's argument.

"I'm an engineer so I know what I'm talking about".

Heiwa:

Actually read the report and stop trying to convince people that did that you have any clue what your talking about. Go back to fooling children your BS does not work on rational adults.

Origami makes more sense.
 
there's no evidence that column # 79 failed. If the column had failed, we could identify the failure in the beam.
 
If Heiwa really is an Engineer, he job must be designing appliances for the Acme Company.

For those who don't want to fry their brains by taking Heiwa off ignore like I did, a simple summary of the OP is:

There is no such thing as progressive collapse, because friction, strain and energy absorption always arrests collapse progression.

We now return you to the physical universe.

Then please offer up your analysis of the collapse. NIST has provided a Typical floor plan detailing the column grid for each floor for your reference. Based on the observations of the collapse where in this typical plan layout did the collapse initiate? And can you elaborate on your conclusion?

"This is a forum for the scientific"
If you have anything to add to this discussion now would be a perfect opportunity for you.

Is it just me or is there a whole waiting from full of kooks just waiting for this thread to drop off page 1 so that they they can start their own "Why WTC7 should not have collapsed " thread?
Does JREF have like a pastel colored padded waiting room?
 
Heiwa is correct. The government is too incompetent to carry out valid scientific work. Only a socialist would think otherwise.

Heiwa? The guy who thinks you couldn't destroy the WTC if the top part had fallen from 2 miles up and hit it? The guy who forgets to include gravity in his calculations? The guy who couldn't even paraphrase the NIST theory correctly in the OP?
