Snow loads on a trough roof (butterfly truss)
Snow loads on a trough roof (butterfly truss)
(OP)
I am reviewing the design for a structure with a slight inverted pitch (2.385 degrees) to the center. The width of the building is 294 feet. I am concerned about snow accumulation in the valley (6'-4" height difference). Since the slope is inverted, I am not sure the flat roof provision (less than 5 degrees) of ASCE 7-05 Sect. 7.3 pertains. Should this be evaluated as a sawtooth roof in Sect. 7.6.3 or is there another provision that applies?

I would check fOR drifting and saw tooth might be one way to go.
REMEMBER THIS - IT WILL LEAK - IT WILL ALWAYS LEAK!!!!!!
