Since it does seem to be "standard practice", I was hoping to find an alternate load path or theory that justifies this approach, being that it does seem to perform adequately. And yes, I think failure of the carbon fiber wythe connector (or more likely the...

    Precast sandwich panels: composite design during lifting/handling

    I'm designing precast prestressed sandwich panels with carbon fiber wythe connectors such that the panels will behave as "partially composite." The few design examples I have found determine the level of composite action based on the in-service condition (simple span) and corresponding shear...
