Wind drift-Load combination-CSA14

[Sayed Mohamad]

Hi dear friends,
Would you please guide me through calculating the wind-drift according to CSA load combinations?
That is to say, What are the load combinations shall be used to obtain wind drift?
thanks for your time in advance,
mohamad

For me, I just do a straight 1.0W in each direction separately, and then a 0.75W in each direction concurrently. I do not check the drift in the vector addition direction, but just each orthagonal direction. Whether that is correct or not, who's to say. But it seems to work and seems to be on par with the others in our office and locally.
