How To: Combine Snow and Wind Loads
How To: Combine Snow and Wind Loads
(OP)
I work at a curtain wall glazing company, and I am currently working on a spreadsheet to compute combined snow/wind loads. Looking at the NBCC, using table 4.1.3.2 in division B part 4, I'm having a hard time understanding how to combine the loads I am presented with. To better understand my problem, I'l give a quick example.
there is an angled skylight, spanning 15m by 20m. The angle of the skylight is 16deg. For simplicity, the windload found is 50psf, and the snowload found is 20psf.
Now my question is, how would I combine these two loads using the NBCC as a rference to acheive a signle distributed load for analysis? Any reply will be helpfull. Thanks.

RE: How To: Combine Snow and Wind Loads
You can use following Load Combinations, if there is no live load:
1. 1.5(Snow) + 0.4(Wind)+ 1.25(dead)
2. 0.5(Snow) + 1.4(Wind) + 1.25(dead)
