For A22 (BYS)> = 4 condition is not met.
The Complete Message:
For A22 structural system type, Building Height Class (BYS)> = 4 condition is not met in (X / Y) direction.
In TBDY 2018 Table 4.1, Building Height Class (BYS)> = 4 limit is set for A22 structural system. The program gives a warning because the building carrier system A22 is selected and the BYS> = 4 condition is not met.

Building Height Class | Building Height Ranges Defined According to Building Height Classes and Earthquake Design Classes [m] | ||
DTS = 1, 1a, 2, 2a | DTS = 3, 3a | DTS = 4, 4a | |
BYS = 1 | HN > 70 | HN > 91 | HN >105 |
BYS = 2 | 56 <HN ≤ 70 | 70 <HN ≤ 91 | 91<HN ≤105 |
BYS = 3 | 42 <HN ≤ 56 | 56 <HN ≤ 70 | 56 <HN ≤ 91 |
BYS = 4 | 28 <HN ≤ 42 | 42 <HN ≤ 56 | |
BYS = 5 | 17.5 <HN ≤ 28 | 28 <HN ≤ 42 | |
BYS = 6 | 10.5 <HN ≤17.5 | 17.5 <HN ≤ 28 | |
BYS = 7 | 7 <HN ≤10.5 | 10.5 <HN ≤17.5 | |
BYS = 8 | H N ≤ 7 | H N ≤10.5 | |
Solution:
If Building (BYS) = 3 , it can be used for carrier system types A11, A12, A13, A14, A15 . The selection of the carrier system type can be changed with the Analysis Settings / TBDY 2018 Earthquake Code wizard by changing the appropriate carrier system, ductility level.
If Building (BYS) = 2 , it can be used for carrier system types A12, A13, A14, A15 . The choice of carrier system type can be changed with the Analysis Settings / TBDY 2018 Earthquake Code wizard by going to the appropriate carrier system changes.
If the building BYS = 1 , the buildings specified in the article 3.3.2.2 of TBDY 2018 will be classified as high-rise buildings according to Section 13, according to the condition , the building should be designed according to the principles given in Section 13 of TBDY.
