Re: Canopy Roof Wind Load

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If you take a closer look at the Figure 6-6, you'll notice that there is no
line in the table for a roof of zero degrees.  That's because you should add
10 degrees to the roof pitch, then enter the table.  So, for a roof of 0
degrees, enter the table at 10 degrees.

For your 10 degree roof, enter the table at the 20 degree line, and I think
you'll see a significant difference.
