RE: ASCE 07-2005 Unbalanced Snow

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

Look at the bright side, the academics are making your analysis more closely
reflect studies.  

Not to say I don't like the unbalanced load provisions the way it was and I
haven't seen change you've talked about yet, but when the wind is blowing
right, I have seen snow thicker near the downwind ridge and less near the
eaves.  On my house the wind blew all the snow off my roof except for the
about a foot on the downwind ridge during the last month.

ASCE 07 has changed the unbalanced snow load requirements yet again.  The
snow load profile places the maximum unbalanced load at the ridge.  As
someone who has spent a fair amount of time in snow country, I don't think I
have ever seen that load pattern.  The commentary indicates there are
"studies" available to document this pattern but doesn't cite any references.
Does anyone know those references or studies?
