WTC7 perimeter inward bowing

Postby achimspok » Fri Feb 05, 2010 1:22 pm

Tom F.K. aka "tfk" implied some WTC7 perimeter inward bowing was never discussed before.

The last official theory based on an unsupported column length of 5 floors causing column 79 to buckle. "Unsupported" means the loss of lateral connections. I still don't know how an unsupported column could pull or push e.g. floor slaps horizontally. Nevertheless, I see forward for the details by tfk.
