NCARB Vignette - First Attempt!

[lalutt05]

Any comments are appreciated. I feel like I'm missing something, it didn't take long...

The thing that seems to be missing are the columns at the lower level. I don't see any columns carried down from the upper level and no columns to support the lower level beams.

Bearing walls not recommended. Use all steel.
N-S joists at entry is more efficient.

Also keep in mind - you don't have to be symmetrical in your columns. Columns in the corners of lower walls are a good measure too.

Coach,
Dorf says that joists should preferably span the smaller dimension of a roof bay. I get that spanning the joists NS over the entry is more efficient because it eliminates the beam at the East edge, but would adding a beam at the East edge and spanning the joists along the short span be a fatal flaw ?

Your quick response appreciated. Testing Thursday.

The advice is either incomplete or misguided. Yes, you always look at the short span first, but it is not always the best way to go.

Hard to know how much efficiency matters. On this particular problem, no, but if you start adding 3, 4, 5 extra beams? Quite possibly failing.
