How do you design for Fatigue with Stand-Off and Grout? I keep getting this error message: The current fatigue regulation (EN1992-4 EOTA TR061) does not cover stand-off applications.
Thank you for your question, you are right that within Profis Engineering a fatigue verification cannot be performed in case of a stand-off installation with or without grouting. This is due to the fact that the relevant anchor design guidelines and the qualification process do not cover such an application. To be more precise, such an arrangement is excluded therefore in such cases any solution provided by HILTI would not be covered by the approval and guidelines. I would suggest contacting your local HILTI office for further assistance and also if possible to consider the possibility of reducing the grout thickness maybe increase the plate thickness to compensate?
