Does anyone have any good recommendations for a technical book on building design. By building design I mean basic 1-2 story building construction using wood framing. I don't want to become an architect or anything, but I'm currently designing a dream shop. I doubt I'll ever get to build it, but it's fun to model some of my ideas in SketchUp. I'm trying to span a 30' long distance without having any center supports. I'm sure there are a bunch of ways of doing this, but since this is a mostly intellectual exercise it got me thinking about different architecture techniques and the ability to handle load for a given span, etc.... Again I'm not looking to become a professional, and I understand that any book I read will only give me a small percentage of the knowledge needed since there are so many variables, but I enjoy learning.
Thanks.
