RE: Live load under mechanical and solar units at roofs

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Actually, I didn’t know that was part of the code to begin with.  What section in the old code contains that provision?  Oh, and beer ALWAYS helps.

Subject: Live load under mechanical and solar units at roofs


In the old code, I was able to find a section that stated that we can ignore the roof live loads under mechanical units.  I was trying to find this in the new code, but I could not locate it.  Does anyone know if this is still true and where in the code is it stated.  Also, does anyone know if this applies to live loads under solar collectors.  It is a Friday and I am tired of looking at the code.  Maybe a glass of beer will help me.
