We have the beam designed. Torsion was considered the ties are closed type. I am looking to see if there are concrete references that may have new data or procedures.
Joints at loadbearing masonry/reinf concrete interface: To accomodate differential movement between dissimilar materials, its standard practice to cut a joint in the cement render at the position of the masonry/concrete interface. I have a project where the Architect is vehemently opposed to the joint for aesthetic reasons. I'm investigating reinforcing the render accros the joint. By providing a bond-breaker (to increase the area over which the render can move) for a distance (say 5") on both sides of the joint and reinforcing the render for another 5" beyond, I'm reasoning that the slab/masonry movement will result only in a series of micro-cracks in the render rather than a big uncontrolled crack. Anyone have any experience on this?
