RE: Rw for cantilevered columns

[Subject Prev][Subject Next][Thread Prev][Thread Next]
No guessing is required. Based on the 1996 Accumulated Supplement to the
1994 UBC, p. 82, Table 16-N is amended to include Cantilevered Column
Elements. Rw=3.

||cantilevered column systems in buildings and non-building
||structures.  While

||non-building structures.  Also, Rw=3 is approximately
||1.4*(R=2.2), which
||puts it in the right ballpark.

||What Rw (UBC 94) does people usually use for a free standing column
