Joe, your plan I shard to read, but I think you are indicating a shear wall off of a cantilever. Hat doesn’t work. What do you provide for shear walls? I would expect (2) diagonal braces in the short direction and (2) moment frames in the entire long direction to allow for windows and doors to work on the elevations. Do you need fireproofing on 1 12/” deck with 3 ½” concrete? What rating are you expecting? In the real world you would probably increase the deck dimension to get a 2 hour rating without adding spray fire proofing. Rather than GWB I would recommend spray-on fire proofing for columns and beams. Check a UL book for details.
Joe, where are the columns? Turn them on. The back-span beam on a cantilever is typically the same size as the cantilever. If you have a W24 for your cantilever, the beam behind the column will be a W24 as well. This beam will be able to span more than 12’. The ideal column bay width to support a cantilever is about three times the length of the cantilever.
werner, i have an updated plan that i will post along with the rest of the final postings in the next several days, i will incorporate those comments as well as researching the ul details for the columns. the typical column size is a w8 or 10 except at the cantilever line, significantly larger (w18??). I guess the typical moment detail I am looking at using is a beam being bolted to a column (using stl angles) and having a stiffner plate (welded to column).
We currently live in a 1927 Craftsman house. Recently completed a total kitchen remodel, a complete gut to the studs and build out with our own two hands.
Our family consists of three cats: Shrimpy, Cocktail and Diesel.
My fiancee, Missy, also graduated in architecture from Ohio State. She recently passed the LEED AP exam and has several active green building projects through her firm, WD Partners.
An interesting quote from Renzo Piano during an interview with Archinect: "I think it important to note the difference between style and coherence. If you're talking coherence, I love it. If you're talking about style, then I start to wonder."
