Structural Damage to the Financial District

Posted by michael on from the engineering-challenge dept.

An anonymous submitter sent in a couple of links to damage reports on the World Trade Center complex - a nifty 3D map of the center and surrounding areas showing which buildings have been damaged or destroyed, and a discussion of how exactly they're going to excavate the below-ground area of the complex considering that it is below sea level.

  1. Impact of falling buildings by MGKoch · · Score: 3, Informative

    On a somewhat related note, a German news channel stated today that the impact of the falling WTC was 1/25 of the power of a A-bomb. That's massively, if you take into consideration that the whole energie is unsealed within a place with one of the highest population densities in the world.

    There have been some 1500 workers at the scene constantly since Tuesday, and I believe they are working as fast as they can. You have to realize just how dangerous the rescue efforts are.

    Consider that the only survivors they found (last I heard) were rescue workers -- fire department, police, etc. These were people who arrived after the fact, but before the buildings collapsed. There is still danger of more collapses, especially when dealing with the rubble that is piled on top of the massive basements of the WTC towers. One false move and you could lose any remaining survivors down there.

    As for the subway, they did try, and it's hopeless at this point. I believe it was flooded or something to that affect, and possible the subway tunnel could collapse; there's simply too much risk in that route. I do know that they did consider that possibility, and came to the conclusion that it simply wasn't worth the risk.

    I can certainly understand your feelings on this, but believe me they are and have been trying to move as fast as they possibly can. It's just very dangerous, not to mention just how massive the destruction is...

    An article from today's NY Times has disturbing topographic images of the site generated using lidar.

  4. Foreign Deaths at the WTC by White+Shade · · Score: 3, Informative

    Is anyone aware of the fact that more British nationals died in the WTC than have in most, if not all, the IRA bombings in London (or the rest of the UK), ever?

    Tons of non-americans died in the WTC, a fact that i haven't heard mentioned on the news at all..
