Progress Foundation-First Floor Framing Plan











The parking garage shall consist of 12" thick reinforced concrete foundation walls bearing on a 24" thick two-way flat plate. Interior columns shall be 18" diameter reinforced concrete columns. First floor framing shall consist of reinforced concrete beams up to a depth of 30" at the transfer beam locations. The first floor slab shall be a 12" thick two-way flat plate.

Lateral loads shall be resisted by a combination of rigid connections and reinforced concrete bearing walls that shall extend from parking deck slab to roof deck.

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.
