- See Section 2.323.
- Response parameter is pseudo-acceleration for 5% damping.
- Data become scarce for T > 2s due to cut-off frequencies used and, therefore, do not derive equations for
longer periods. Limit of 0.03s is based on Nyquist (sampling rates are generally ≥ 100Hz) and high-cut
filtering used (generally > 30Hz). Note that this conservative choice is based on the study of Douglas and
