Interior Wall Out-Of-Plane Load
Interior Wall Out-Of-Plane Load
(OP)
I have a residential shower with the two surrounding walls stopping a few feet short of the ceiling. The walls do not attach to each other and one end of each wall is attached to an exterior wall. As such, one end of each wall is unbraced. I want to cantilever a 3 1/2x3 1/2" steel or engineered wood post up from the floor system below by sandwiching it between some joists (all new construction). When designing the cantilevered posts and subsequent moments in the joists, what would be a reasonable loading to apply to the post. If I simply use 5 psf on the shower wall, I only get a 35 lb. reaction at the top of the post. Does this seem like a reasonable design load? I could imagine some antics in the shower that might require higher design loads :>

You could use a handrail assumption and use a 200# or 50plf but this will make it rather large. the steel is probably excessive since your base will be so flexible and Engr. Post i worry about the environment. I am guessing there is no way to have a transverse girt at the top of your cantilever to make your walls Simple Spanning??
RE: Interior Wall Out-Of-Plane Load
The girt would interfere with the aesthetic as the Arch wants the walls unattached over the shower entry.
50 plf at guardrail height would translate into about a 50 lb point load at the top of the post as would a 200 lb point load at guardrail height (each wall is 4' long x 7' high). I think I will go with that. Looks like a 4x4 PSL post has too much defection. I guess HSS will be req'd

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

If two little old ladies are using the showers, that may be a tad excessive.
