Parametry odpowiedzi modalnej można ustawić w module dodatkowym RF‑DYNAM Pro - Equivalent Loads w zakładce Spektrum odpowiedzi. In the Code Parameters table → Type of Spectrum → Modal Response Parameters, the default is set to "No Modification". This setting can be seen in Figure 1.
Changing this to "Force Related" in the drop-down window will divide the response spectra by Ie/R based on Sect. 12.9.1.2 [1]. Additionally, in the Code Parameters table > Coefficients, the Seismic Importance Factor (Ie) and the Response Modification Factor (R) can further be set.
