From least to largest span:

One way slab (15-30 typ)

One way joist system (20-30typ)

2 way slab

2 way waffle slab

The first 2 seem interchangeable?

  Carie,

  Not sure if this book is on your radar and perhaps you have it, but I strongly recommend that you get the Architect's Studio Companion for questions such as this one.  They have excellent tables in the front of each chapter - for example the Structural Systems chapter - that tell you in what situations certain structural systems are ideal to use.  Criteria such as "lowest initial cost" or "largest span without columns" or "shallowest members" - things like that.  I had questions like this on the ARE and read and reread these tables quite a few times as a part of my studying.  Same thing for MEP systems too - they tell you which are to ideal to use and when.  Highly recommend it.
