OK, lets say you have 40'x40'x60' tall building.  On the top of building you have parapet that is 30'x20'x15' tall.

So, when I design the components and cladding on the parapet, what is a?  (10% of least horizontal dimension).  Is it the 40' or 20'?

P.S. Why is that all of the examples are always simple blocks when in reality it is not sad.   

Never, but never question engineer's judgement

RE: wind design

The 10% least horizontal dimension, as I understand it, is with respect to the building. So this would apply to the 4 ft from the edge of the building. If the 30' parapet is centered on the building, then the 10% would not apply to the parapet.

RE: wind design

Assuming your "parapet" is actually a screen wall (I gather that from your description, since a typical parapet would not be 15' tall), then I would use the 40' dimension.

yes a screen wall, but I have to design it like a parapet.

If you continue on in that section it also gives minimums, so any way 10% of 20 ft is 2 ft. 10% of 40 ft is 4 ft, and as stated in that section the minimum is 3ft. I would use 4ft for a (40ft length) and move on.
