Wind loading on irregular roof
Wind loading on irregular roof
(OP)
Hi,
I am often faced with the problem of developing wind loads using ASCE 7 for irregular shaped roofs. It seems strange that ASCE has no fixed procedure to deal with irregularities when these are more common than regular roofs in real life.
Please refer to my attachment for the specific case I'm referring to. I'm using chapter 30, Fig 30.5-1 in ASCE 7-10 to determine wind loading on flush mounted solar panels on this roof (as indicated in red in the drawing). I have a couple of questions:
1) Am I using the correct Wind method in ASCE to size the attachment for the solar panels
2) Using ASCE 7-10, Fig 30.5-1, how can I determine

a) Mean roof height h: Would this be the mean roof height for every single part of the roof? Including the protruding tower at the end? Or would it only include the sloping part highlighted in red?
b) To determine the "Least horizontal Dimension, again should I use the entire building or just the part where the panels occur? This can also be problematic for other, more irregular buildings. This would include L-shaped Hip/Gable roof buildings, for example
