Wind Load on Roof Wall
Wind Load on Roof Wall
(OP)
Hello,
I have a building in which there are rooftop structures that are enclosed by a 14ft high wall on all four sides. The wall is going to be supported off of vertical members with kicker braces going back to points on the roof. The mean roof elevation is around 22ft. In reading ASCE 7-05 it seems like the appropriate method for analysis is to consider it a solid freestanding wall and set h = the height of the top of the wall and to consider the ground surface as actually the roof elevation as there is no wind passing below the wall. However, it is on a roof, so I'm unsure as to whether or not this would be considered a rooftop structure. I would think "rooftop structure" mostly refers to penthouses, or other equipment in which there are typically four walls and a roof.
Any thoughts from the community?
Thank you.

There is nothing exciting about either wind or seismic. It is SDC A and 90mph wind exposure B. Lateral support for building is masonry shear walls and gravity support is steel columns.
