It is determined automatically according to Table 3.2 , depending on the S DS parameters defined in for Building Use Class and DD - 2 .


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

While the Design Based on Strength (DGT) approach is applied, the short-period design spectral acceleration coefficient defined in for Building Use Classes (BKS) and DD-2 in accordance with Article 3.2 of the TBDY is determined according to Table 3.2 , based on S DS parameters . Earthquake Design Class (DTS) is determined.

TBDY 2018 Analysis Setup Wizard , Building Use Class (BKS) and S DS by using parameters Earthquake Design Class (DTS) automatically determines.
