I design embeded connection in the column using Hilti Profis, I have shear force for gravity load, The connection is failed (concrete edge filaue in direction Y, eventhough I do not have in Y direction any force (perpendicular to the column edge).
The force if parrell to the column center line.
Hi Kangryeol,
Section 17.7.2.1 within the ACI 318-19 Chapter 17 anchoring-to-concrete provisions requires analyzing edges perpendicular to the direction of the shear force (17.7.2.1a or 17.7.2.1b) as well as edges parallel to the direction of the shear force (17.7.2.1c). Section 17.7.2.1c states that edges parallel to the direction of the shear force are permitted to be twice the value determined from either equation 17.7.2.1a or 17.7.2.1b as well as taking the modification factor for edge effect, Ψed,V, equal to 1.0.
The PROFIS Engineering software represents the provisions of Section 17.7.2.1c through the modification factor Ψparallel,V. For edges perpendicular to the direction of the shear force, Ψparallel,V = 1.0. For edges parallel to the direction of the shear force, Ψparallel,V = 2.0. For more information, please see page 200 of the PROFIS Engineering Design Guide.
