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.
For members designed based on compression, or tension, the effective slenderness ratio control is made according to CYTHYE 2016 (GKT & YDKT), AISC 360-16 (ASD & LRFD), or EN 1993-1-1 codes.
According to TBDY 2018 and CYTHYE 2016, the effective slenderness ratio KL/r ≤ 200 for compression members should be satisfied.
According to TBDY 2018 and CYTHYE 2016, the effective slenderness ratio KL/r ≤ 300 for tension members should be satisfied.
ideCAD Structural automatically checks the slenderness ratio according to axial tension or compression conditions.
Possible Solutions:
Brace length can be reduced. If the element length is reduced, the axial compressive strength increases.
Steel element cross-section can be enlarged.
