2012 IBC Wind Deflection Limits
2012 IBC Wind Deflection Limits
(OP)
I am designing to 2012 IBC for the first time (solar carport) and notice that the wind deflection limits in table 1604.3 remain unchanged.
But wind has changed to a strength level load so these deflection limits are now more restrictive.
I think this is a mistake and instead of "W" they should say 0.6W
Footnote f was changed by multiplying the previous 0.7 x 0.6 to equal 0.42 (but I would have left this alone and made the change I mention above).
What do people here think?

I don't have any particular qualms about this. I disagree that they should have ignored the footnote, since having one scaling factor in the table heading and another in the footer is a recipe for confusion.

I would use the service loads.
