Re: non-constrained embedded pole - 97 UBC 1806.8.2.1 "d" definition

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Scott,

I have always interpreted this as follows:  For cases where 1/2" of movement
is not permissible, the maximum would be 12 times the tabular value.  For
cases where 1/2" or greater movement is permissible, twice the tabular value
may be used to a maximum of 15 times the tabular value (otherwise you could
go to 24 times the tabular value).  I have no basis for this other than
opinion.
