I've got a series of wood roof trusses ~5 years old and they show signs of minor splitting at their bottom chord splice locations. See picture below, bit hard to see.

How does ETABS handle the input of snow drift loading? I can't seem to find any options for it. I am dreading that I might have to input tapered loads individually on all my frame members.
On the same note, is there any way to assign, for instance, a...
