If you are interested in space frames, then you will want to have a look at some references regarding the direct stiffness method which is what the majority of all frame analysis programs are using (users have already posted links). It may also be useful to look at the flexibility method as you work up to the direct stiffness method. The flexibility method is easier for myself to understand, however I have written programs for analysis of 3D space frames in the past and I have always used the stiffness method as it is much easier to code in my view.
My recommendation:
1) Look at the principles of virtual work
2) Try examples of flexibility method (start with truss)
3) Try examples with stiffness method (try a portal frame or something)
I studied these topics before I started using any software and it helps a lot. Any one who uses software like frame analysis packages without first having at least some exposure to these methods is being pretty "optimistic" I would say.
Good Luck
