Well in the UK, any proposals have to get a Building Warrant (or Buildings Regulations Approval, depending on where you are) in order to show compliance with statutory codes. Of course they're not the construction drawings, but they're still pretty detailed. These are then public documents, and can be FOIed in the normal manner.
Don't you Americans have a similar system? I should note, however, that in the UK there would be an FoI exemption for particularly security-sensitive sites. |

A scale model will not work, because the physical behavior is not invariant under scaling.
Imagine you are enlarged a factor 2, then your weight becomes 2^3=8 times more, but the area of your muscles and strength only enlarges by 2^2=4 ===> problem. You can however emulate/simulate ? a scale model if you use different densities/strengts/whatever and give it a different g value by accelerating it |

This was posted in the Loose Change thread. Is this what you were looking for?
http://news.uns.purdue.edu/UNS/html4...Sozen.WTC.html Maybe you could get in touch with the guys who made this computer model and ask where they got the plans for the WTC. |

Not directly related...
But have a look at this. I am utterly stunned. This guy has created an entire 3D computer model of the WTC complex. And I mean ENTIRE. He even has the escalators etc... it's truely incredible. Here's a picture of the wire frame to give you an idea of the detail. He appears to intend to do the underground stuff and everything. -Andrew |

I'd like to see it. What the hell...it would probably be interesting.

I will.
First, not any local collapse will lead to a global collapse. You need an entire floor to collapse, with several floors above it, and pretty much fail the whole floor at the same time (so the mass above that floor drops together as a live load). On 9/11 this was accomplished by: 1) The impact of a jet airliner, with an estimated energy yeild (from kinetic energy alone, not counting the ignition of jet fuel) equivalent to 4,000 to 6,000 lbs. of TNT. 2) Subsequent fires, which weakened the remaining support columns...columns that were already over-stressed due to the removal of many columns by event 1. By examining the structural properties of steel, and the average size of the support colums in the WTC, I've calculated that you'd need thousands of pounds of explosives to cut the supports sufficiently to cause collapse of a single floor. Just over 3,000 lbs. of C-4 as a matter of fact (over 4,000 lbs. of TNT). Although, technically, if you used shaped charges, had direct access to the steel core and exterior columns (meaning cutting into walls), and only took out just enough of the columns to have a good chance of collapse (instead of taking them all out) you could get it just below 1,000 lbs. of explosive, if you're lucky. More realistically you'd still need 1500 to 2000 lbs. Even more realistically you'd have to limit your placements to areas that could be concealed and accessed, which would mean non-optimal placement and would also limit the ability to use shaped cutting charges...so I'd revise that estimate to 2,000 lbs. as a ballpark figure. You'd need hundreds of tons to cut supports on all floors, or for a typical CD situation. Of course, I've actually done some of the calculation on this, using information that is not that difficult to obtain. A bit easier for me, as I've had some demolitions training and experience, but anyone can get the data. But, as with most of the "Truth Seekers", spending a few days getting in touch with people who know demolition, and finding the sizes of the columns, the equations governing charge sizes, and doing a bit of multiplication is too much work...the 3,000 who died isn't worth that to you, eh? |

Bolding mine.
Just a quick question... how hard is "tried very hard"? After all, you came on here bitching and moaning about the plans for goodness knows how long before we discovered you hadn't even tried to get them. Does "tried very hard" mean sending an e-mail? |

From Cinefex issue 107, page 16. Regarding the visual effects for the movie World Trade Center:

In Design News, Professor Abolhassen Astaneh-Asl was in New York days after the collapse to get information. He is a professor at UC-Berkeley in Structural Engineering. He collected perishable data, took photos and then proceeded to make computer models of the structure. He did have a grant from NSF to do this work and was able to obtain construction drawings and design documents from the Port Authority.
Specific to the docs, the article said:

So Truthseeker is partially correct in that not just anybody can request and receive those documents from the Port Authority. But they have been released to Professor Abolhassen Astaneh-Asl. Lurker |

Here is an interesting story on Mr Astaneh-Asl's theories about why the WTC buildings collapsed.
It seems his ideas are somewhat controversial as he seems to be suggesting that if they'd been built according to New York City Building Codes (they weren't) they would have stayed standing longer. (Incidentally, in this story he says he was sent a copy of the building plans by an official from FEMA.) |
