FW: Discontinuous shear wall load path

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Sharad:
Paul had it right.
A code change proposal was approved for the 2002 IBC Supplement that clarifies
the code language.  The wording will be something like the following:

"Columns or other elements  subject to vertical reactions from discontinuous
walls or frames of structures having plan irregularity Type 4 of Table 1616.5.1
or vertical irregularity Type 4 of Table 1616.5.2 shall have the design strength
to resist special seismic load combinations of Section 1605.4.  The connections
from the discontinuous walls or frames to the supporting elements need not have
the design strength to resist the special seismic load combinations of Section
1605.4."

So your floor joists, their support connections, and their supporting post or
beams, including  the structural (not geometric) strength of the supporting
foundations should be designed using the special load combination.   By
"geometric" strength I mean the soil pressure and stability calcs used to size
the foundation pad.

regards,
Martin
