I thought all the reports stated that the towers had a "steel reinforced cast concrete core structure"? Wouldn't that mean that they were constructed with "steal reinforced concrete"?
Either way, the question I have posed is about the Willis (Sears) Tower Core Structure and it's importance in supporting the structure itself. With the WTC Towers used only as an example and nothing more.
ON a side note:
I have been searching till my fingers hurt for pictures of the Sears Tower core while under construction. I would love to be able to the elevator shafts because that stuff has always fascinated me! LOL! I have always been curious how that worked in a tower like this one. I know that sounds weird, but I love the engineering and design behind the tower almost as much as I love the tower itself!
