Structural Spans
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.
