Drift in raw output & baseline correction
I am finding the output from Strata has significant drift in the displacement time history – and even when baseline correction is selected the final time history continues to show drift. To remove I need to do a band-pass filter in Seismosignal which changes the phase of the motion & making comparison between models problematic in the time-domain.
I wonder if there is a cause of this in the numerical algorithm? I do not get the same drift in EERA or Deepsoil v5.1 (MKZ model).
