Parapet?

Parapet?

Parapet?

(OP)
This is a new facade for mall. It projects about 15' above the roof deck. The EOR provided this detail. Would you consider this a parapet for wind loading or due to its height, would it be considered some other type of structure? (like a freestanding sign). The wind loads end up being pretty huge on it if treated like a parapet. I am only doing the C&C calcs. on the individual members. The EOR is handling the MWFRS on the mall (don't really know how he will get that to work out)

Thanks.

RE: Parapet?

From having seen similar construction going on near my house, I would consider it a parapet for wind (and snow) loading calculations.

You could say it's a parapet, but it looks more like a mansard to me with the vertical extension below the roofline.

@Mike;

How is that treated in ASCE 7-10 under C&C? I do not see any design info for mansards.

RE: Parapet?

It's a parapet. You would treat a mansard as a sloped roof.
