After spending weeks of or looking for picture of construction or plans of the Trade center I conclude that there aren't any, with the except of distant shot from a great distance. Doesn't the Fire Department usually relie on plans provided by the city of building in volve in a fire for evacquation. But all plans for the WTC have disappeared. I did find one picture of the floor system taken from the Noth tower looking down on the South tower. It appears to look like the 64 ft Truss's were hung off the small 36" Truss's. Now there must have been a beam or perhaps a Dbl or Triple truss at this point becase the 64' Truss was much biger,, I think I read that is was almost twice as big and the short ones. But everything was attached to that flimsy rim or steel that held the collumns together. Also and not to forget the nonexistance of spines for attaching the columns together. The columns were only bolted end to end and with 4 bolts. The interior cor is unknown but was much more substantial as it did house the stairs and elevators. I have also read that the steel the the base floors was provided by Japan because American Steel Manufactures could produce the gage required. I also just was a blurry cross section of the beam to clad and am not exactly sure of it's attachment except that it would have made me nervous to lean against the windows after seeing it. As the clad, with unknown attachment to the interior onlt touches the column on it's interior side witch was then covered with plaster. There is no scale given but basically the windows hand off the clad wich looks to have about 1/2" of air space between the column and the clad. I guss I am assuming theat the lateral shear would have to have been the floor but I don't thing that is possible. I have read a lot of independant engineers on the web who definitelt question the building integrety. Even to the fact that the panels were stagered in a stair step manner. The question that drings to mind is that both planes crashed into the buildings at an angle, and it would be interesting to know if it was the same angle as the steps to produce the most amount of damage. I think the other interesting thing to note is that WTC 7 was not built in the same manner and I sure can't see any reason for it to fall straight down into it foot print. Exccept for the recording or Larry Silverstein telling someone who called him on the phone that perhaps they should just pull the building and the seconds later the building did just that, collasps on itself. Now dropping a building on itself seems to take quite a bit of time to weaken it and set explosives. However it happens in just minutes. Which leads to the question, are tall building built with Demolitions incorporated into the building when it is built just for the purpose of building removal? Building 7 was built 10 times better than the 2 towers from what I have seen. I also don't go with the Collasps idea/ dream of FEMA's report, the domino theory. I have looked at the video of the collasps. When Tower 2 came down the top 50 stories broke off and started for the plaza and should have ended up there I believe, but at the last minute it seems to be sucked back into the buildings foot print and disappear. I thought it was interesting that everything seemed to be sucked back in like you were watching a movie being played backwards. It would seem to anyone that if you dropped the center cor what you saw would would have indeed produced what did happen. Now the North Tower, it would seems, if you want to drop a building all you have to do is set a fire on the top floor and wait for the steel to melt and then the whole building will come down. I don't under stand why when all the dust settled why there was no central cor standing for either building, just lots of the flimsey exterior loddey sections going up 20 to 50 stories, maybe that was the Japannes steel. I am just a carpenter and a designer, not a structional engineer but if I was building a house with the attachments I have seen I wouldn't have been able to get a permit.
