Info
  • The relevant earthquake level specified in TBDY 2018 is selected by the user according to the design according to the strength or the design according to the deformation

Infotip
  • According to TBDY 2018 - 3.5.1 - Table 3.4 (a), DD-2 selection is required for Normal Performance Target and Earthquake Ground Motion Level and Performance Level are determined automatically.

...

Within the scope of TBDY 2018, four different earthquake ground motion levels are defined below.

...

There is approximately 1.5 times the difference between each earthquake level. Different earthquake levels are defined to be used in the 'Performance Assessment and Design ' section, which was not available in DBYBHY 2007 and was added as a new assessment and design approach with TBDY 2018 for the first time . In accordance with the philosophy of 'Performance-Based Evaluation and Design' , design is not made with a single earthquake level, it is necessary to make calculations and designs for different earthquake levels.
