Interior Masonry Wall Bracing in PEMB
Interior Masonry Wall Bracing in PEMB
(OP)
Hello,
I have a partial height (15') masonry wall that I am kicking/bracing perpendicular to a Z-Purlin(s) in a low-seismic region.
In order to keep the roof deflection / or any expansions from producing a force at the top of the wall, does anyone have any ideas for a medium-duty connection detail for both the top of the wall and at the roof.
Will also span a cross member to engage an additional adjacent purlin for the loading.
Thanks for any feedback in advance.

It is tricky in how to use any slip connections, but at the same time being able to resist horizontal loading on the wall.
Thanks again everyone,

OH MY GOD, THIS WAS A DISASTER. They added my brace loads, to their (wrongly calculated) wall out of plane forces. This in turn created huge anchorage loads. They complained about the brace incessantly. They never got it right, so one day when I was out of town, one of my guys got talked into removing the brace and having the wall span to the top of the building. I ripped him a new orifice, but the damage was done.
It's amazing that when the sales guys show up, they can do anything, but when you try it yourself, it's like re-inventing fire.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I hope this helps!

I think you are overstating the lack of stability of Z-purlins laterally. They do have bridging which braces the purlins together, and this bridging should connect to a stiffer element at the eave or ridge. After all, the purlins have to be stable enough to allow safe installation of the roofing. Even concealed fastener roof systems provide some stability to the purlins, otherwise the purlins could move rather than the roofing.

And would including a bond beam at mid-height of the wall enable it to span further between braces.
Thanks again all!
