Hello to everyone

I want to make seismic calculation in a code which is not included in the code list in PVElite, So i´m entering the seismis spectrum in the option Res. Spectrum but i have a doubt: the program ask for a combination method but the code that i´m actually using does not contemplate a combination of modes for static calculation, but only for dynamic calculation. My question is does PVElite make dynamic calculation? There any recommendation about literature in the selection of the method?
Thanks for yours answers
