control joint in CMU wall
control joint in CMU wall
(OP)
Normally, at control joint in a cmu wall, specifically control joint a cross a bond beam, it's called out that horizontal reinforcement to be discontinued and dowel into and grease one end. This is most commonly occur at openings. But, at the diaphragm level, the bond beam is attached to a continuous angle. The angle is than used to transfer cord force.
If the angle is spaning continuously across the control joint, would this inhibit the control joint?

The bond beam at the window level, assuming there exist a control joint here, starting the end of the window level bond beam running vertically up to the roof (diaphragm). You would run the reinforcing steel in the bond beam continuously across the control joint at the window level and at the roof level? Also, you would rake out the exterior mortar and caulk it?
The situation I'm trying to describe has a continuous angle spaning across the top of joist seats. the joists are pocked into the CMU wall. The continous angle is anchored into the CMU wall to transfer shear. If the continous angle span across the control joint and the bond beam, this would inhibit the control joint and incompatible with the bond beam at the window level since the bond beam at the window level has no continuous angle across the control joint. How can I eleviate this problem? Thank you for your respond.
