Load combinations? Cranes, live load & snow?
Load combinations? Cranes, live load & snow?
(OP)
I am adding hoist beams and cranes to the underside of a roof in an existing building, and am not sure about the loading combinations. I am using the National Building Code of Canada where live load is described as min loads, snow and cranes including impact. I don't think it is reasonable to use full live, snow and crane loads all at the same time. Is there a clause that allows me to reduce one or the other?

With EQ the strength design becomes probabilistic or service level with LL feduced even further.

Same provision was in Uniform Building Code UBC-97
