This section will look at the snow loadcases when the headcode is set to AISC.
The snow loadcases that are set up will depend on the head code that is being worked to.
Note: All loads and lengths of loads are assumed to act on a horizontal projection of the roof surface.
Once set up these loadcases are standard loadcases so you can include them in combinations in the normal manner.
In the Snow wizard... you specify the Snow Loadcases to be set up from the following list:
-
Minimum Snow Load - for low sloped roofs
-
Balanced Snow load - uniform snow load and rain on snow load
-
Unbalanced Snow Load - the number of cases required being chosen to reflect the number of wind directions considered
-
Drift Snow Load
-
Rain on Snow Surcharge
