BKS = Building Use Class
DTS = Earthquake Design Class
DD-2 = Earthquake ground motion level with 10% probability of exceedance in 50 years (recurrence period 475 years)
S DS = Short period design spectral acceleration coefficient
3.2. EARTHQUAKE DESIGN CLASSES
Based on Building Use Classes defined in 3.1.1 and Short Period Design Spectral Acceleration Coefficient defined in 126.96.36.199 for earthquake ground motion level DD-2 , Earthquake Design Classes to be taken as basis in design under earthquake effect in this Regulation (DTS) will be determined according to Table 3.2 .
