Drift snow load

Drift snow load

Drift snow load

(OP)
I would like to ask if you have in the Structural plans note for flat roof truss  

snow load 46psf
drift load 106psf

what is the load added in Engineering as trapozoid load?

106-46=60psf or
106psf

if you have already added in the Engineering snow load 46psf.

Thank you!

RE: Drift snow load

Ask the author of the note.  I use drift load at the edge of a low roof with a step to a higher roof; tapering down to standard snow load a specified distance out from the step and continuing. (This would be the trapezoid with 46 as a minimum and 106 as a maximum).  If the roof distance is less than the taper distance, the minimum load is a truncated trapezoid , greater than the minimum.

RE: Drift snow load

If there is a drift load, I will show a diagram in the notes of the application of the load.  

If it gets too complicated, I will show a snow load plan diagram where the higher loaded areas are highlighted, with cross sections as necessary to clarify the presentation.
