I am analyzing a roof mounted solar panel array with the panels being supported by a racking system and the racking system is mechanically attached to the roof. They system stands about 2 feet (at the low side) off of a flat roof and is tilted at 30 degrees. I am analyzing the racking system as a MWFRS using ASCE 7-05 Figure 18-A and am comfortable with this wind loading.
The question that I keep asking myself is "Do I design the attachment to the roof using MWFRS loads or do I use Component & Cladding loads and if I use the C & C loads, what figure would I use?" I am leaning towards using MWFRS loads based on the information in attached article, but am still struggling with this. And if I am going to use C & C loads in this case, would I treat that entire array as the "component" and use Fig 6-11B?
Any thoughts on this would be greatly appreciated. Thanks!
