So I've got a project where I designed a 2-wythe brick wall with a grouted collar joint (total 10" thick). The design also called for horizontal joint reinforcing to connect the 2-wythes together, spaced at 16" oc. As luck would have it the contractor did not fill the collar joint nor did he install the joint reinforcing.
I'm thinking of using those retrofit wall ties (Simpson Heli-Tie, etc.) to hold the wythes together and make this wall act like a composite section. Does anyone have any resource/references for calculating the section properties of the wall assembly with no grout/mortar in the collar joint? The ties will have to resist the shear to force composite action so I think I could just use the material/section properties of the ties to check strength on that. Any other ideas?
