Top Down Demolition.

Astute Perspicuous said:
Hey dude...it's NOT crush down...it's 6 floors coming down on 5 and you can see in the aftermath that the pile is still basically 4 stories tall so wrong again.

No... you can't.

The debris pile in the video is completely obscured by dust clouds.

You are either lying about having watched the video or lying about it's content.

The lower part is already partly destroyed (to initiate the controlled destruction) and what is left intact below is much smaller than the (bigger) upper, intact part dropping down. Clever French controlled demolition starting at the bottom. Looks like WTC 7!

The Turks tried to do something similarly (starting at bottom) recently but failed! Top part rolled away.

why do you lie?

Is it just part of the "twoof condition?"

do some BASIC research.

the lower part was NOT partly destroyed. The building was emptied like you do for CD. They then went in and WEAKENED 3 floors IN THE MIDDLE OF THE BUILDING (the part B you dolt). They PULLED the supports and PART A (which was the SAME SIZE as part C) then crushed down (just like Bazant suggested)

Now it would help a LOT if you even bothered for some BASIC research before spewing CRAPOLA. Reminds me a great deal of that thread you keep dodging... the Ronin point collapse...

Engineering degree? Remind me which country it is from, I want to make sure when I visit it I pay PARTICULAR attention to any bridges, buildings, or ships I get on... cuz after all "C's get degrees."

I love it when twoofs show their ignorance to the public.

REally? Classic controlled demolitions MAKE NOISE because the use explosives. Where is the NOISE from the explosions? Huh Heiwa?

Really? Didn't do your homework again did you? Spewing CRAPOLA w/out having any IDEA what it is. Balaz had the 3 middle floors weakened and then had the supports PULLED OUT. Gravity driven collapse.

How does having the support across 2 floors PULLED out = "classic controlled demolitions?"

According Bazant we start with a small upper part C and a big lower part A structural assembly. Then we drop C on A in order to destroy A. C is intact all the time of the famous 'crush down'. A is destroyed in steps; a set of columns and one floor of A are compressed compacted into a part B(azant) one after the other. When all of A has been compacted into the part B (B = 1/4A in height, i.e. the uniform density of A = 0.25 becomes uniform density of B = 1. Then 'crush down' is complete.

According Bazant then 'crush up' of C starts, i.e. C, with uniform density 0.25) becomes another part on top of B with density 1.

After crush down of A and crush up of C - both with uniform density 0.25 according Bazant - there remains a compacted box of rubble - part B - with uniform density 1.

As a Finale Grande of Bazant the rubble box of part B (it is abt 100 m high (!) as the tower (parts A + C) was initially abt 400 m high and was compressed to 100 m) spills out on ground around the foot print - for immediate re-cycling, etc, etc.

Only problem with this amazing fairy tale is that you cannot compress a structure - part A - with density 0.25 by another structure - part C - with same density 0.25 and produce a compacted rubble part B with density 1 that only consists of part A elements. It is NWO physics of the worst kind.

And to suggest that this compaction of B is done by gravity alone has no scientific foundation at all.

Well, I have heard a bunch of so-called, self proclaimed "debunkers" bring up that they have never seen a top down implosion.

Well, here is your chance. Wow, how close it does resemble something we saw 8 years and 15 days ago.

Have an excellent day.

P.S. Do you list "debunker" on your resumes and applications?

Yes, it resembles the towers quite a bit.

So we agree that if some storeys in the middle of a building are structurally compromized, it can lead to global collapse with large pieces of debris being ejected to distances comparable to the height of the destruction zone, and with large amounts of dust being blown for a considerable distance.

So now we are moving (finally). Now, we can observe in the video that no demolition charges are fired during the collapse, in fact it seems that no sizeable explosive charges are used at all. Instead, the building is weakened in another way. This is very useful as there are buildings nearby, and normal explosive charges would blow out hundreds of windows in the surrounding buildings.

The same was observed in the WTC towers: Similar collapse behaviour, no sounds or effects of large explosive charges.

So we can conlude that a WTC 1+2 style collapse can be initiated by the structural compromising of a few storeys in the middle of the building.

No need for discussing free-fall, toppling, arresting, ejecta, pulverizing, etc, etc. Those have all been shown, among other things by your video, to be normal features of a collapsing building, regardless of the initiating cause.

All we may still need to discuss is the possible modes in which the impacted storeys in the WTC towers could have been structurally compromised enough to initiate the collapse.

Thank you for your contribution!

Nice attempt at a DERAIL. We are now talking about the video listed, the Balaz V, demolitions. So the Part A, B and C are in Balaz V. Part A (the top) is EQUAL to the size of PART C (the bottom). Part B is "pulled" and creates the RUBBLE.

where does it arrest the fall? AT which floor does the arrest happen?

Do some basic research and get back to me. Did they weaken the lower floors? (hint, no)

Was it a "classic controlled demoltions?" (hint, no)

they weakened 3 floors in the MIDDLE. The top then CRUSHED DOWN the bottom which was the same size.

Come on twoof... do some research, you are supposed to be an ENGINEER...
 
1. We need cat pictures.
2. The building is not the slightest bit similar to the WTCs, so comparision is completely ridiculous.
3. The middle three floors have been prepped to come out, then the top half comes down and crushes the bottom half...so???
4. You are not able to see what remains after the demolition due to the dust cloud.
5. I will have a nice day, thanks to this bit of humor.
6. Keep trying pal...
7. I actually list "NWO operative" at the bottom of my resumes.

OH Heiwa... and other twoofs.

http://www.strimoo.com/video/12509995/Mort-d-un-batiment-MySpaceVideos.html

pay particular attention from 1:40 to 2:05
and 2:21 to 2:25

Good slow motion starts at 2:30 and goes until 2:50.

My french isn't the greatest, but it looks like it says soemthing about the subbasements...

(so yet again Heiwa, you show that you have done NO research into this collapse (like ronin point) and are just spewing garbage. Tsk tsk tsk. come ths unprepared to my classes and you would FAIL.)

I believe the word is... OWNED.

Is there a crush up at the end.. is the top crushed? Is that RUBBLE I see on the top of a GRAVITY DRIVEN COLLAPSE?

Oh my.... I think you owe them $1,000,000 Heiwa... because that definately met the Heiwa Challenge.
 
Hilarious. A twoofer attempts to post a video proving a "twoof" point but does the complete opposite. He actually proves exactly what Bazant is saying. [Heiwa mode]If you stack 12 pizza boxes up, then remove the three in the middle, crush down does not happen! But wait what happens in this video....perhaps pizza boxes don't mean a damn thing when it comes to buildings? NO WAY.[Heiwa mode]

Being the reasonable fellow that you are Heiwa, I'm sure that you'll re-evaluate your conclusion after watching the slow motion portion of the video below, yes?

There is really no getting around this one for Heiwa, or astute for that matter.
 
When I read threads like these I can only sit in stunned amazement at the messes truthers get themselves into.

Imagine being a lawyer and presenting "evidence" in court that proved your own client guilty.

:dl:

Folks like Astute Perspicuous and Heiwa should be thankful the TM hasn't achieved that "new investigation" we always hear about. This way their humiliations are confined largely to chat boards and not testimony highlights on CNN.

I'm shocked that someone who believes in such things also cannot do simple math. For someone to feel comfortable enough to lecture folks about a giant evil conspiracy using language like "8 years and 15 days ago" to make themselves look smart, then to double down and call names when their simple error is pointed out is amazing. Only youth can explain an arrogance / ignorance ratio so high as this.

Well, except for Heiwa :)

Instead explosives, they use hydraulic jacks that push the walls and columns of a single floor.

It's a demolition technique very common in France, called vèrinage.

Some examples:

Well, well, well.....this certainly adds to the 911 debate, doesn't it? :D

I'm amazed now one found this stuff sooner.

Apparently the concept of a top-down collapse due to local structral failure isn't quite so rare after all.

I wonder how long it will take the truthers to adopt the "hydraulic jack" demolition theory for the WTC.

I'm well aware of the date. It seems as though you are unable to do simple math. 8 years and 15 days means that 8 years plus 15 days, which would be 8/11/01. If you were referring to 9/11, that happened 8 years minus 15 days ago.

I note a comment on the youtube video in the OP from one "leftysergeant" some 4 months ago. Seems lefty was holding out on us!

Truthers will have to make it much more stupid. It will be super-nano hydraulic jacks powered by mini-nukes or something.
