Applications and Design for Horizonal Shear and Shear Friction in Concrete Structures

In concrete members, shear friction is considered for any interface between two concretes cast at different times, between dissimilar materials, as well as for any existing or potential crack. For composite concrete flexural members, a shear interface is created when fresh concrete is placed against hardened concrete. Design for both shear friction and horizontal shear requires careful consideration for the transfer of forces across the interface. This webinar will discuss relevant provisions for the design of these interfaces in concrete structures. The discussion will also include an overview of changes from ACI 318-19 to ACI 318-25 along with requirements in the new ACI 319-25 for precast concrete structures.
