BYS = Building height class
DTS = Earthquake design class
DD-1 = Earthquake ground motion level
DD-2 with a probability of exceedance of 2% (recurrence period 2475 years) in 50 years = earthquake ground with a probability of exceeding 10% in 50 years (recurrence period 475 years) earthquake ground motion level
DD-3 = the probability of exceedance in 50 years is 50% (recurrence period 72 years)
DD-4 = earthquake ground motion level with 68% probability of exceedance in 50 years (recurrence period 43 years)
SH = Limited Damage
KH = Controlled Damage
MM = Before Migration
3.5.2. Evaluation / Design Approaches to be Applied
18.104.22.168 - Scopes of application of Design Based Resistance (DOT) approach given in Section 4 and Evaluation and Design Based on Change (ŞGDT) approach given in Section 5 are given in Table 3.4 and Table 3.5 .
22.214.171.124 - Preliminary design of fully post- tensioned pre-fabricated buildings defined in Chapter 8 will be made with the DGT approach, and the final design will be done with the ŞGDT approach according to 8.4.3 .
126.96.36.199 - The design of masonry, timber and light steel buildings not specified in Table 3.4 will be made with the Design Based on Strength (DGT) approach according to Chapter 4 .
