I wish I could post my alternate vignette here, but I don't have the right image editing software right now. Still, I have some questions:
1. On framing an exterior porch, is it acceptable to frame it by simply extending the beams and joist system that frame the interior adjacent rooms? Would you need a beam at the exterior wall? For example, in the NCARB practice, let's say the common area was the same height as the covered entry. Assuming beam spans were acceptable (no overhangs), could you extend the north and south beams to frame the porch and use the same joist system to cover both spaces? Or would you need a beam running north/south between the common area and the covered entry? I ask this, because on this particular alternate vignette, it seems the most economical.
2. If columns are spaced at 35' on center, would the span of the beam be 36' or 35'? (For programs with a limit on the span of the beam.)
3. Can beams go in the Window Wall?
Thanks.
