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 Slenderness check failure.
Slenderness control under the influence of axial force, tensile force and axial pressure force in steel brace design 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 It is done by taking into account the buckling conditions.
In TBDY 2018 and ÇYTHYE 2016, it is stated that the slenderness ratio of brace members should not exceed the limit value of KL/i ≤ 200.
In ÇYTHYE 2016 Chapter 7, it is stated that the slenderness ratio of elements under the influence of axial tensile force should not exceed the limit value of KL/i ≤ 300.
ideCAD Structural automatically controls the slenderness ratio according to axial tension and pressure conditions.
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.
