Thanks for your help, StrEIT. Concrete is one of my weaker subjects and I'm trying to get a handle on it. I'm having difficulty visualizing this problem as a column and not as a beam. The fact that it has 3 layers of reinforcing (looking at it in section) is throwing me off track.
Ok but why would the strain diagram be 0 at one end and 0.003 at the other? Would it not resemble a typical strain diagram with 0.003 at the top and fy/Es at the bottom?
I uploaded a sketch of the column that I am dealing with.http://files.engineering.com/getfile.aspx?folder=56bbb076-3a75-4cec-b075-bcc58cf9b515&file=column.jpg
What about finding the moment of inertia of the transformed section and dividing that by the product of the transformed area of the section and the c distance? I tried going this route but it's the c distance that is throwing me since this is an L shaped column and not a plain old rectangular...
