How can determine the Seismic Coefficients Ss & S1 for a structure, if the seismic map in the form of peak ground acceleration PGA?

Old seismic codes provide seismic map with peak ground acceleration (PGA) values with a 10% probability of exceedance in 50 years. The new codes provide the Seismic Coefficients (Ss) & (S1)....
