Unfortunately Hilti does not have a comparison of seismic requirements between the US and Europe.

Hamidreza,

Since the ETA and ACI are two different design standards, there is not a correlation that can be made between the ACI Seismic Design Categories (SDC A-F) and ETA Seismic Concepts (C1 & C2 Class I - IV), as well as the fact that the ETA Seismic Concepts will vary between countries.  For design purposes, many designers will either use ACI/ICC-ES data or ETAG/ETA data in order to verify the anchor capacity. 

Let us know if you have any additional questions.

Regards,

Bryan
