The "Earthquake" frame serves to input earthquake parameters. Directions of input earthquake effects are displayed on the desktop.
If not provided by measurements, the coefficients kh and kv can be calculated following the approach adopted from EN 1998-5.
Analysis of earth pressures while accounting for an earthquake is described in the theoretical part of the help in the chapter "Influence earthquake".
The earth pressure increment from the earthquake can be considered over the entire length of the structure, or its effect can be limited to a certain depth.
