RE: Shear Wall Deflection IBC vs. UBC

[Subject Prev][Subject Next][Thread Prev][Thread Next]

The "h/b" multiplier in last term of the equations seems to be correct in
the UBC. I am not sure why it was left out in the IBC. The h/b multiplier
uses simple geometry to correlate the vertical deflection of the holdwown to
the horizontal deflection at the top of the wall.

Has anyone noticed that the last term of the formula for the deflection of
wood shear walls in IBC is not the same as the one in the UBC? The formula
in SI units appears to be quite different also. Which one is correct?
