[HOW TO APPROACH THE STRUCTURAL SYSTEMS VIGNETTE]
May 6, 2012
Now lets draw the joists and decking. Decking always run perpendicular to the joists. Both the joists and decking should be drawn to the centerline of the wall. This is important for all decking, joists and beams you draw in this vignette! The program states that you cannot cantilever beams, so sticking to this method avoids doing that.
Keep in mind that we use 48” o.c. joists because the program says the deck can support a span up to 4’-0” you can use 32” o.c. but that wouldn’t be as efficient as 48” o.c. joists.
