Hi, I'm doing a performance analysis, in the report, as in the photo, why does the Earthquake ground motion level show DD-3 instead of DD-2, why does it show like this, can we do it as DD-2? How can we do it?[/ quote] Hi, DD-3 information is printed because it is required for Relative Floor Shift Control DD-2 Earthquake Ground motion level information is given at the top and in the TBDY 2018 Earthquake Parameters Report.
