Study on SCFs distribution for CFST KK-joints with internal ring stiffeners under bending moment

Puntos clave

• SCFs distribution is crucial for understanding the performance of CFST KK-joints under bending moments, ensuring structural integrity.
• Maximum SCFs reached 1.5 times baseline values, highlighting variations based on the presence of internal ring stiffeners.
• Analysis using stiffness analysis methods elucidates how internal stiffeners affect SCFs in CFST structures under loading conditions.
• The findings may enable improved design approaches for CFST KK-joints, though verification in real-world scenarios is needed.
