85% Reduction in Unbalanced Snow Load
85% Reduction in Unbalanced Snow Load
(OP)
We are doing a structural analysis of an existing fabric covered steel building (curved roof) and the original design calculations show a 85% reduction in the unbalanced snow load. We were wondering where in ASCE 7-05 this reduction is referenced.

The justification is that the figures given in the code are an absolute worst case scenario and unlikely to happen very often e.g. you have to have strong winds AND a full snow load on the rest of the roof for it to happen AND all the snow has to move.
