[HOW TO APPROACH THE STRUCTURAL SYSTEMS VIGNETTE]
May 6, 2012
Questions / Concepts (from areforum.org)
What is the maximum span of joists? 30'
What is the maximum span of beams? 40'
Where should I draw the columns, beams, bearing walls, joist boundaries, and decking boundaries? Draw all elements to the center lines of the base plan walls.
Should I use bearing walls and/or columns? All-column and beam solutions are recommended, because there are less rules to remember.
Should I include a beam underneath a clerestory window (if the lower roof joists run parallel to the clerestory)? Coach says, "yes." lug-nut says "no." Lengthy discussion here: http://www.areforum.org/forums/showthread.php?t=203291
If a rectangular decking section can span over multiple joist areas, should I draw the decking as one or two elements?
Either approach is OK.
Should I draw beams continuously, or stop and start the beam at intermediate columns? Either approach is OK. Drawing continuous beams is quicker.
Can joists and/or beams extend from an interior space to an exterior "covered entry" space? Coach says "yes"
Can I cantilever joists and/or beams?
No, per the vignette's program
