This is what every core column was standing on in the bedrock. There was no concrete anywhere in the towers except the floors. You would have to realize how heavy the buildings would be if there were concrete in every column from top to bottom. Or even some of the columns, for that matter. They had to use a special light-weight concrete mix for the floors to keep the weight down. If you haven't seen the following link, there's some good reading there: http://www.abovetopsecret.com/forum/thread208023/pg1 Yea. I didn't know about the light concrete floor mix. As the diagram shows the only parts that are reinforced are the parts where the core rests. I think this is specific for each base, but I'm not sure if the sky lab concourse have these features. I think the space between the steel and the perimeter of the column is drywall. I'll definitely read through the link. At first I thought the lower core had concrete casing however as some like Grit pointed this is unlikely for the upper levels. Edited by mynameis, Nov 22 2008, 01:55 AM.
