    For those preparing to investigate demolition its important for everyone to familiarize themselves with the terms and requirements in demolition preschool keeping in mind that all properly executed demolitions result in a total "collapse" of the target structure.

    Every industry has its own slang and jargon and in the demolition world like trap shooting words like pull or shoot are used to initiate the release of a clay pigeon or initiate a demolition and words like vertical and footprint are used to distinguish the difference between simply tipping a structure over on its side or removing its support structure to attempt to get the bulk of the structural material to fall as vertical as possible when there is not enough room to topple it onto its side, which requires the least preparation and is the most cost effective method for destruction.

    The objective of building demolition that is toppled on its side is to remove the support structure from one side of the building, much in the same manner as chopping down a tree which will cause the structure to fall in the direction of the removed structure.

    Here is an example of a structure that has had its support removed on one side and it thus topples over on its side. (in this case a failed vertical demolition).


    [​IMG]


    you can see how the building just rolls right on over, sort of like a trougher.


    another intended and failed vertical demolition where the bulk of the material topples while the core is left standing.



    Another illustrating that crush down does not work with steel construction.

    [​IMG]


    another, only this time it is a collapse not by demolition but by natural causes and simple structural failure.

    [​IMG]

    we can see how it very slowly begins to give away and then completely falls over on its side damaging the building across the street.

    Demolishing a building by the toppling pr tipping method is the most simple and unsophisticated method by which to bring down old buildings and is also the most economical for labor and materials.

    Demolishing a building with the intent for a vertical drop is a little more tricky and requires considerably more resources as you will need to hire a structural engineer to choose the best places to strategically cut columns in a manner that causes grouped global or sequentially global or fully global simultaneous failure of several supports in groups or sequential groups or all supports in sequence to achieve grouped sequential or total simultaneous failure. So this can get a little tricky and requires a good deal of skill as we can see from the two failed demolitions above that substantial damage can be inflicted upon adjacent properties should any step in the process such as placement detonation or timing fail as seen in the following pictorial;

    [​IMG]

    examples of planned "vertical" demolition commonly known in the industry as dropping it in its own "footprint" are:


    [​IMG]


    another demonstration of near simultaneous removal of all supporting structure in for vertical drop.


    [​IMG]

    another

    [​IMG]




    and again demonstrating near perfect sequence timing;:


    [​IMG]





    so class who can describe for us the different requirements to plan a vertical in its own foot print demolition compared to the elements required to topple a structure on its side style demolition?

    It will take weeks to fully describe just how moronic this thread is.

    Not a one of the videos you showed us is in any way relevant to the collapse of WTC7.

    prove it

    this is only preschool

    nothing real difficult here.

    are you having problems already?

    Not a bit. You made the absurd claim, so the burden of proof is on you. Let's hear some proof that any of them are at all related even to each other.

    I am teaching basic demolition illustrating the different requirements between a vertical in its own footprint demolition and the requirements for simply tipping a building or structure over on its side.


    as you can see you are the one making claims.

    So PROVE IT!

    WTC7 was not a controlled demolition, and did not collapse into its own footprint.

    In the agregate four of us know about ten times what you do about CD. We just cannot see what you are trying to say here. So far, it smells like the run-off pond from a barn yard.

    now all you need do is prove it

    Read the NIST reports, as well as the follow ups by MIT and Oxford.

    If you can point out specific faults in their evidence and findings, do so.

    Kokomojojo trial lawyer
    Kokomojojo chemistry expert
    Kokomojojo digital imaging expert

    And now

    Kokomojojo demolition expert.

    And he must be an expert's expert because he's the only one in the world that would write this run on sentence:

    Though it's funny that the digital imaging expert and the demolition expert didn't recognize that this image is an animated FX shot for a movie called, He Was a Quiet Man.

    One clue might be that the parking lot is somewhere in the middle of the Hudson river judging by the WTC and the Trump building in the shot, But I'm no expert.

    Psst. They didn't even bother to remove the trees from battery park.

    We don't have time to recite the entire NIST report. It is accepted as factual by most rational human beings. If you have a problem with any of it, present you proofs. They will have to be pretty detailed and you will need to present clear alternate explanations rather than just the usual childish "nuh-uh" that we are used to hearing in 9/11 discussions.

    Bear in mind that you are trying to argue with people with professional experience in some of the applicable fields. In some cases, didsinformation as to the underlying principles of buildiong safety can lead to public harm, so do not expect a public safety professional to be at all forebearing if you engage in such hazardous conduct.

    You do realise this gif is a fake right? I mean come one, that looks more cartoon than Scooby Doo.

    Verinage demolition; demolition without explosives. This is achieved with hydraulics that push structural members out of alignment, allowing the top portion of a building to then demolish the structure below via gravity alone, without the use of explosives.

    FB, I would love to see the moment connections on that "building" to keep it together like that........hahaha

    Anyway, I, for one, am glad we have an expert like Koko handy to keep things straight.

    I think they refer to that on Civilization™ as "Future Technology".

    aka: a player to be named later.

    Don't be an idiot. Jello has been around for centuries.

    Military grade explosive nano jello, however...

    Does this 'nano jello' come in lime and cherry?

    Would you like to add something to this thread about demolition? Perhaps you could comment on Koko's use of movie special effects footage?

    Demolition...Okay..
    Demolition was obviously used to take down WTC7.

    Koko's use of footage...okay.
    His use of footage DOES demonstrate how easily said footage can be manipulated.

    Thanks again boss. "Report"....I got it. Thanks for your leadership.

    So you agree with Jojo's use of a cartoon to demonstrate reality?

    You and I have different understandings of the word "obvious." The WTC7 was not demolished using any demolition industry techniques. There is no evidence that the building was prepared for demolition. There was no evidence that the building was intentionally weakened prior to the collapse. There's no evidence that the building collapse was controlled. There's no evidence of explosives or demolition cuts in the steel at all.

    The only thing you find obvious is that the video footage looks kinda similar to a controlled collapse. Clearly anyone with Koko's self professed preschool level understanding of demolition would agree with you. Thankfully people with more than a preschooler's assessment of the event studied the collapse and have a better understanding of how the building failed.

    Does it? How does it do that? Do you know how long it took to create that footage? Do you know how many people worked on it? Do you know whether that footage actually depicts a valid structural model, or just some artist's impression of what would happen?
