What procedure do I use to calculate the horizontal shear transfer with the composite Girder-Slab System?
Chapter 4 of the “PCI Manual for the Design of Hollow Core Slabs”, Second Edition is a standard reference that engineers use to calculate horizontal shear transfer elements, i.e. collectors, chords, and drag struts. When considering the connection at the D-Beam, typically, the hollow core shear strength is less than the grouted beam’s shear strength.
