The document provides an analysis of anchor forces for a proposed anchor system in Vietnam. It analyzes 21 anchors attached to a 1,500mm x 950mm x 9mm steel plate embedded in cracked concrete. The maximum tension force is 46.651 kN which satisfies the concrete breakout strength capacity of 271.623 kN. The steel strength, pullout, and concrete cone capacities are also sufficient to resist the highest anchor loading of 4.535 kN. Therefore, all anchor capacities exceed the design loads and the anchor system is approved.

6 Displacements (highest loaded anchor)


Short term loading:
NSk = 3.359 [kN] dN = 0.033 [mm]
VSk = 1.693 [kN] dV = 0.068 [mm]
dNV = 0.076 [mm]
Long term loading:
NSk = 3.359 [kN] dN = 0.053 [mm]
VSk = 1.693 [kN] dV = 0.102 [mm]
dNV = 0.115 [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 Anchor require rigid anchor plates per current regulations (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 Anchor calculates the minimum
required anchor plate thickness with FEM 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 Anchor. Input data and results must be checked for agreement with the
existing conditions and for plausibility! 
• Checking the transfer of loads into the base material is required in accordance with EOTA TR 029, Section 7!
• The design is only valid if the clearance hole in the fixture is not larger than the value given in Table 4.1 of EOTA TR029! For larger
diameters of the clearance hole see Chapter 1.1. of EOTA TR029!
• Your design has selected filled holes. Please ensure that there is a proper method to fill the annular gap between the fixture and HIT-RE 500
V3 + Rebar 16mm, and contact Hilti in case of any questions.
• 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.
• Characteristic bond resistances depend on short- and long-term temperatures.
• The design method SOFA assumes that no hole clearance between the anchors and the fixture is present. This can be achieved by filling
the gap with mortar of sufficient compressive strength (e.g. by using the HILTI Seismic/Filling set) or by other suitable means
• The compliance with current standards (e.g. EC3) is the responsibility of the user
• An SLS-check is not performed for SOFA and has to be provided by the user!
• The characteristic bond resistances depend on the return period (service life in years): 50

Fastening meets the design criteria!
