Tim, why are your slabs so thick?
Do you use them as heat sinks or do you think you need that thickness for structural reasons?
Both, I am using them for thermal mass and to acheive the spans up 30' the Studio Companion seemed to indicate the need for a 12" thick slab. Am I reading it incorrectly (page 125)?
Tim,
Are you using a two-way reinforced flat slab or flat plate? I came up with a 10" slab using the two way flat slab at a 30' span. You could definately go a little thinner.
Tim, most of your dimensions are (or could be) below 30'. The 39' imension defenitely calls for one more column. Most concrete buidlings I was involved with (residential) used slabs slightly less thick than the thinnest indicated in that table. So, my bad, I didn't check the companion when making the comment, I fell back to reality.
