Wind loads on parapet walls
Wind loads on parapet walls
(OP)
If there is a nonpourous (concrete or masonry) parapet wall, separated from the building below by a concrete roof, why would the GCpi be added or subtracted to GCp? The commentary in ASCE-7 reads "using the value of GCpi for an enclosed building may be appropriate". They hedge with "may", but the GCpi is in equation 6-24.
Just not seeing it. Maybe someone could enlighten us.

Basically you multiply your wind load at the top of the parapet by 2.5 and design for that.

I agree that these values are still high, and above about 7' in height I would be inclined to use solid sign type loads instead as I do not think the wind tunnel testing included parapets above that height.
