VSk = 8.625 [kN] dV = 0.7382 [mm]
dNV = 0.7922 [mm]

Comments: Tension displacements are valid with half of the required installation torque moment for uncracked concrete! Shear displacements
are valid without friction between the concrete and the anchor plate! The gap due to the drilled hole and clearance hole tolerances are not
included in this calculation!

The acceptable anchor displacements depend on the fastened construction and must be defined by the designer!

7 Warnings
• The anchor design methods in PROFIS Engineering require rigid anchor plates per current regulations (AS 5216:2021, ETAG 001/Annex C,
EOTA TR029 etc.). This means load re-distribution on the anchors due to elastic deformations of the anchor plate are not considered - the
anchor plate is assumed to be sufficiently stiff, in order not to be deformed when subjected to the design loading. PROFIS Engineering
calculates the minimum required anchor plate thickness with CBFEM to limit the stress of the anchor plate based on the assumptions
explained above. The proof if the rigid anchor plate assumption is valid is not carried out by PROFIS Engineering. Input data and results
must be checked for agreement with the existing conditions and for plausibility!
• The equations presented in this report are based on metric units. When inputs are displayed in imperial units, the user should be aware that
the equations remain in their metric format.
• Design is only valid if hole is filled to remove clearance, clearance as per EN 1992-4 Table 6.1
• Checking the transfer of loads into the base material is required in accordance with EN 1992-4, Annex A!
• The design is only valid if the clearance hole in the fixture is not larger than the value given in Table 6.1 of EN 1992-4! For larger diameters
of the clearance hole see section 6.2.2 of EN 1992-4!
• The accessory list in this report is for the information of the user only. In any case, the instructions for use provided with the product have to
be followed to ensure a proper installation.
• For the determination of the y re,v (concrete edge failure) the minimum concrete cover defined in the design settings is used as the concrete
cover of the edge reinforcement.
• Please note that this design utilizes user defined material safety factor values that differ from the default values recommended in EN1992-4.
Partial Safety factor value: gc = 1.500
• Load transfer from supplementary reinforcement to the structural member shall be verified by the responsible structural engineer.
• With supplementary reinforcement and post-installed anchors, please ensure that in the jobsite the rebars are not drilled through.
• The characteristic bond resistances depend on the return period (service life in years): 50

Fastening meets the design criteria!
