Applying Wind Load to a Continous Stud
Applying Wind Load to a Continous Stud
(OP)
If you have a stud (say wood or CFS) that is continuous past the roof level to form the parapet, how are you applying the wind pressure?
The stud is analyzed as an overhang cantilever. Do you apply wind load to then entire stud. Or do you check 3 cases - apply load to the entire length, just the cantilever, just the span. Does your answer change for deflection?
What if the stud was continuous over 3 stories? Are you checking alternate spans or applying a uniform load to the entire stud?
Thanks?

I don't think loading the wall and parapet simultaneously significantly changes the curvature of the stud at the roof level compared to loading the parapet alone. While codes are based on maximum displacement (L/xxx), the curvature of the cladding is what counts. If I am happy with the deflection but need to reduces the L/xxx to satisfy a picky plan checker, I will check the deflection with the wall and parapet simultaneously loaded.
I assume this is only non-bearing walls since most bearing wall systems are platform framed (no continuous studs). If it happens to be a bearing wall, the continuously loaded member may reduce the P-Delta affects.
