snow drift and sliding loads
snow drift and sliding loads
(OP)
I am working on a roof design that has a 45 degree roof slope that suddenly changes to an almost flat roof (1/4" per foot). How can I determine the snow sliding and drifting requirements? The snow drift calcs in ASCE-7 are for a flat roof to flat roof with a step down, not a sloped roof with a drastic slope change.
