Fatigue Performance of Bird-Beak SHS Gap K-Joints under Brace In-Plane Force

Bin Cheng et al.

Summary: This study conducted fatigue tests on bird-beak SHS gap K-joints, revealing that the brace crown region had the most severe stress concentration, coinciding with the crack initiation location, and confirming that experimentally obtained SCFs can accurately predict the crack initiation location.

Fatigue behaviour of thin-walled cold roll-formed steel sections

C. D. S. Souto et al.

Summary: This paper presents experimental research on the fatigue behavior of thin-walled cold rollformed steel sections commonly used in rack structures. A new design S-N curve is derived from innovative testing methodology to support the revision of Eurocode 3. Additionally, a local fatigue approach incorporating residual stresses and elastoplastic stress analysis provided consistent fatigue life predictions.
