This message is created by specifying the element name and floor on which it is located at the beginning of the report.
For example,
SBR001 BASE STORY Steel Brace ductility check failure.
Ductility control in steel brace design with high ductility level is carried out by taking into account buckling conditions according to TBDY 2018, Design, Calculation and Construction Principles of Steel Structures (GKT and YDKT), AISC 360-16 (ASD and LRFD) or EN 1993-1-1 regulations.
In TBDY 2018, it was stated that the slenderness ratio should not exceed the limit value of KL/i ≤ 200 for braces with high ductility level and limited ductility level.
Possible Solutions:
A brace system can be created in such a way that the lengths of the braces whose names and floors are given are shortened. As the element size decreases, the slenderness value will decrease.
The cross-section size of the brace member can be increased.
