This article is the second of two (the
first ran in March '99), working
through the structure of a Garrison with
its characteristic second-story overhang.
The second-story joist must carry not
only the interior loads, but also the load
from the roof and the exterior wall on
the overhanging end (see Figure 1).
In the first article we calculated the
loads on the second-story joists. There
are four distinct loads:
• the interior dead load from the second
level structure
• the interior live load from people
and furniture in the upstairs space
• the dead load onto the outside end of
the joist from the roof and exterior
wall structure
• the live load from snow on
