# [HOW TO APPROACH THE STRUCTURAL SYSTEMS VIGNETTE]

May 6, 2012

Using the principles discussed above, lets add joists, columns, beams and decking to the lower level.

Keeping in mind the spacing of the beams, add columns so they do not exceed 40’-0” in length, but without drawing too many columns.

By drawing the upper level first, we are able to see an overlay of the upper floor plan, which allows us to place the columns directly under (as seen in the red box)

# So we add the remaining columns and then draw the beam for both sides:

We have 3 beams within 15’-0” of each other! This is necessary because: The column on the left most within the red box is supporting a column from above (beams cannot transfer column loads) The middle column in the red box is supporting the column from above and the column to the right most in the red box needs to support the south east corner of the roof above the toilet room, seating area, kitchen and prep & stor. rooms.

6. Now let’s draw the decking and joists.
