Story Drift: 1994 UBC vs. 1997 UBC

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Can this be true?

"Flagpole" columns (i.e., inverted pendulums)
h=8 ft.
D=Delta
Ds=Delta sub s (service)
Dm=Delta sub m (maximum inelastic)

1994 UBC:
Ds < 0.005*h=0.48 in
Dm=Ds*3*Rw/8=0.48 * 3 * 3 / 8 = 0.54 in.

1997 UBC (1630.9.2)
Dm=0.7 * R * Ds < 0.025 * h
Ds < 0.025 * h / 0.7 * R = 0.025 * 8 * 12 / (0.7 * 2.2) = 1.56 in

Is it true that we can now design flagpoles (and steel frames for that
matter) for an allowable drift of three times than before or have I missed
something???
