New Concrete Model

[jwaugh]

I developed a new concrete model for OpenSees based on Chang and Mander's 1994 concrete model. I gave the model out to some people at the NEES Annual Meeting, and it will be in the next release of OpenSees.

If you are using this model please post in here or send me a PM with your name and email so I know who is using it. Thanks
