RE: Boca Code Interpretation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The "and public parking garages" is not included in the Final Draft issue of
the 2000 IBC.  This was voted on by BOCA.  The IBC indicates no special
limitations on LL reduction for parking garages.

The final authority is the Building Official.  Give him a call, but you can
use the IBC as background for your request.

Could someone help me with a Boca Code interpretation?  We have a 4 level
parking deck in Virginia with live loads less than 100 psf.  We want to
reduce the live load for column design but we are not comfortable with the
Code's wording.  Section 1606.7.2.2 addresses live load of 100 psf or less
and includes public garages or open parking structures with exceptions in
the next subsection.

Section 1606.7.2.3 addresses live loads greater than 100 psf AND public
garages and open parking structures for the design of elements which support
more than one floor.

Does this mean that we can reduce the columns' live loads by 20%?
