A numerical study and proposed design rules for stress concentration factors of stainless steel hybrid tubular K-joints

•A FE investigation on SCFs of stainless steel CHS-to-SHS and SHS-to-CHS K-joints was conducted.•An extensive parametric study comprising 324 FEMs was conducted.•CIDECT Design Guidelines were not suitable for predicting the SCFs of the hybrid K-joints.•The proposed design equations could accurately...
