Vegetation Screen Loading?
Vegetation Screen Loading?
(OP)
I have been asked by a client to design some attachments for a "vegetation screens" to a building. Problem is, I have no idea what to design these screens for. The project in question is located in the north east US and I imagine it can high wind loads as well as ice loads. I have some literature from a manufacturer located in CA that gives some anchorage loads, but I don't believe they apply in my instance as my screens are supported 100% by the building. Does anyone have any experience with these?

The link has an engineering report that addresses many of the things your asking about. Also, as they point out, don't forget to account for irrigation piping and heads - if they're used.

That report is interesting, but it does not address this specific case as my system is a trellis system such that the plants will grow up the side of the building, so irrigation and piping will be kept to a minimum at the base of the trellis. I also find it odd that the report doesn't address ice build up on the system as that would add weight to the system that needs to be supported.

Vi=PI*td*As
td=design ice thickness
As= surface area of one side of a flat plate or the projected area of complex shapes.
So for a flat plate of 168 square feet and an design thickness of 1.57 inches I am end up with a Vi=69 ft^3. Or 55.2 ft^3 for a vertical plate (what we have here).
My question is in regards to PI. If my shape is flat what do you include PI in the equation?
