[HOW TO APPROACH THE STRUCTURAL SYSTEMS VIGNETTE]

So, we have 52’-8” between our drawn columns. Thinking ahead to the beam requirement, we need to take into consideration the spacing between beams. The consensus on areforum.org is that the maximum span between beams should be 40’-0”… which means to be efficient, we need to add one more column in between these columns…not two, but one.
With the column added to the north wall and the south wall, we have the appropriate spacing of columns. When spacing the columns on the upper level, take a look at the lower level to see if there are any corners that can be used for framing.
4. Next, let’s add the beam.
A commonly asked question is: Should I draw beams continuously, or stop and start the beam at intermediate columns? Either approach is OK. Drawing continuous beams is quicker. When we draw the beams, draw it in the centerline of the wall that it is being placed into.
