Design Assumptions

1. ETA Values: The ETA values for EOTA TR029 were used in all calculations. 2. Design Standard: The design is based on AS 5216:2021, which is identical to EOTA TR029. The only difference is that AS 5216:2021 uses cylinder concrete strength (f'c) instead of the cube concrete strength specified in EOTA TR029. 3. Anchor Configuration: While the number of anchors is taken as 2 for spacing geometric effect calculations, the resistance is always calculated for a single anchor. 4. Reinforcement: No dense reinforcement is considered in these calculations. 5. Installation Conditions: Category 2 – installation in dry or wet concrete or in flooded hole. 6. Temperature Range: -40°C to +70°C. 7. Seismic Design: No seismic categories are included in this calculation. 8. Splitting and Blow-out Resistance: These resistances are not calculated. The calculation will highlight when these resistances are required. 9. Complex Geometry Cases: Use Sika AnchorFix® Calculation Software for multiple edge distances or for combinations of edge distance and spacing scenarios.

Validation

Results are well aligned with Sika AnchorFix® Calculation Software. The difference in Concrete Cone Resistance is due to the conversion from cube concrete strength in EOTA TR029 to cylinder strength in AS 5216:2021.
