Wind pressure values shall be taken as determined in Components & Cladding. For those structures where snow drift loads are required, see Exception 1 in the referenced code. In combinations 4 and 6, Snow Load shall be takenas the design snow load pu and shall exclude drift surcharge load. In combination 3, Snow Load shall be taken as the totalsnow load including drift surcharge. <br />Page 11 of 111
