Interior CMU Wall
Interior CMU Wall
(OP)
I have an interior 8" thick cmu wall used only for division purposes (non load bearing). The wall spans 5.80m. (between the top of concrete slab below to bottom of concrete slab above). It is connected to the concrete slab below with dowels.
For pressure out of plane I considered the following:
1. W = 10 psf minimum wind load for interior walls.
2. W = 0.40 x SDS x I x Wc for seismic.
My design tells me that I should connect the cmu wall at the top to the slab above using dowels, and with this simply supported condition, I should use #3 @ 16" o.c. as flexural steel. I am also using a 8" x 12" beam at mid height of the wall and a 8" x 12" beam at the top of the wall. I'm also prescribing 8" x 8"columns at 5m. o.c.
Am I missing anything?

for non load bearing walls, it is good practice to provide room for the floor above to move without loading the wall, ie a slip joint. depending of the type of structure this may be more or less critical.

A bond beam (usually 8" high)at the top of the wall seems sufficient, more practical and preserves the modularity of the height unless there is a special height requirement.

RE: Interior CMU Wall
For interior nonstructural partitions 13.3 is applicable. The force will depend on the location of the partition(z) in relation to the overall height of the structure(h). In a high-rise building, the force on the partition on the upper floors will be much higher than the partition on the ground floor.
