Will the snow load drifting double up at corner ?
Will the snow load drifting double up at corner ?
(OP)
Hi Folks,
what I have is a sloped lower roof which is surrounded by higher roof area along the north and east side. I calculated the drift width and drift load which is 6 ft and 30 psf respectively. my question is will the drift load be doubled up at the north east corner ?
Thanks

Your judgement may require you to add some load if the steps are very high and the upper or lower roofs are long. But that is a judgement call not a code requirement.
I havn't reviewed the Washington state Structural Eng's Associations comments on snow for a while so they may also suggest bumping the load up.

Please can you tell me the section in ASCE 7 05 where I can find that the loading need not be doubled. Thanks
