SEAOC seismology opinion regarding 10/Lw factor for calculating rho

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

During the Sept 29 seismology meeting, the committee voted to submit a code
change proposal for the 2001 IBC Supplement No. 1, with the following language:

"In light-frame construction, the value of the ratio of 10/Lw need not be taken
greater than 1.0."

Please note that this is just a proposal, which is subject to possible rejection
during upcoming ICC hearings.

Meeting minutes for the Sept. meeing will be posted to the web server following
the upcoming Dec 3/4 meeting (they exist only in draft form at this time).

For engineers who are currently engaged in light-frame structural design, SEAOC
can really only recommend that all engineers ALWAYS OBEY THE EXISTING BUILDING
CODE, AS ADOPTED BY THE LOCAL JURISDICTION.  It is public law, and we cannot
recommend any other action.

Wishing you all a great Thanksgiving
