Re: Deflection Criteria

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The devil is in the exceptions ;-)  From the 2003 IBC table 1604.3, note i, For cantilever members, l shall be taken as twice the length of the cantilever.  This note does not appear in the 2000 version, and so I suspect it is not in the UBC (though I don't have a UBC to verify).

As to the code section, the live load + dead load deflection is L/240. Can anybody out there get me a reason to justify I can use 2L/240 for a cantilever beam deflection? Is it specified somewhere in the UBC 97 building code or anywhere ? Any comments on this would be highly appreciated.
