Combined Steel and Concrete Moment Frame in STAAD.Pro V8i

Let me first say I am no Staad expert...but I'm trying to learn.

I have a wind frame that is concrete up to a certain height and steel up the roof.  Is it possible to model this and analyze the combined frame all at once in Staad?  If so could you please point in the direction of a tutorial or example? even just a Staad Editor file would be helpful.  Thanks.
