MEMORANDUM
Item 1: Upper Exterior Balcony
The existing balcony is framed with four double 2 x 10 joists spaced 5 -feet on center,
and cantilevered 6 -feet from the south exterior wall, with a 13 -feet backspan. The rim is
a 2 x 10 plus 2 x 12 beam. Short 2 x 10 joists span from the rim back to the exterior wall,
spaced 16" +/- on center.
Conclusion
Based on a design Live Load 40 psf (match room served), and allowable stress values
for the Douglas Fir/Larch #2 material, the 2- 2 x 10 joists are found to be about 40%
overstressed.
Recommend
In order to meet allowable stress values, the 2- 2 x 10 joist cantilever can be cut back
from 6 -feet to 5 -feet.
