There was a time in Structural Engineering designs where Block Walls were erected and the top three cores of CMU were below a bearing member were left open by stuffing the cores below it with paper or a piece of tar paper was slipped in the block cell to close it off, and then the cores three high were filled with grout and a layer of brick was installed over the CMU to provide a seat for the support of steel bar joists. This is when attacthment was not required for steel support. Then it changed to brick over CMU directly under steel anchor plates to provide lateral attacthment and increase bearing capacities on top of the CMU. CMU bricks were commonly used and also red solid core clay bricks were used for this purpose. Hollow core bricks were never used for this purpose.
Marcel, I have seen the same thing in older buildings up here fwiw,

We’ve got a downtown full of brick bearing walls.

You got that right Larry;
My Company is right now finishing a Re-hab for Bowdoin College in Brunswick, Maine where we totally took out all four floors and the roof system on a building that is 120 years old. The only thing standing and reused was the brick walls which consisted of four bricks thick at the bottom to two bricks thick at the roof line. SOLID BRICK. Mortar, well, you know, they old stuff made with lime. ha. ha.
