I am having a crisis with a flat slab design that I am working on. Shear Stud Rails (my preferred solution) are proving inadequate to withstand the punching shear caused by the high axial loads and unbalanced moments. I have seen other engineering drawings that use I-beams as shearheads. I am unconvinced that these are ductile enough to do the job properly. In this case seismic is not an issue.
In my design code (CSA 23.3, I am Canadian!) the following reference is made: The design of shearheads shall be based on the concepts in the ACI Committee 318 Building Code Requirements for Reinforced Concrete (ACI 318M-89) and Commentary (ACI 318 RM-89)pp351.
I don't know much about the ACI. I also hate when codes refer to other codes when they shouldn't. But that's beside the point.
Question: Has anyone ever used shearheads made of I-beams, and what was the design procedure. The above ACI reference, does anyone know what this is, and how I might make use of it?
