Stress Analysis and Fatigue Test on Partially Overlapped CHS K-Joints

Abstract: This paper presents the experimental studies of two partially overlapped CHS K-joints specimens (Specimens S1 and S2) with through brace subjected to basic and combined loads. The stress analysis of the joints revealed the maximum stress concentration factor (SCF) to be located on the brace side. Then, the maximum SCF was compared with existing Efthymiou's formulae. It is observed that the Efthymiou's formulae are over-conservative in in-plane bending load case (IPB), but in axial load case (AX) are not conser… Show more

“…Similarly, IPB1 and IPB2 are, respectively, the corresponding inplane bending (IPB) loads applied at the ends of the through and the overlap braces. It should be noted that the directions of the IPB1 and IPB2 load cases are selected such that maximum SCF shall be induced at the weld toe along the brace-chord intersection curve [10]. For the corresponding gapped joints, due to symmetry, only the AX1 and IPB1 load cases were applied at the end of one of the brace.…”

“…However, as they were found to be not conservative for the AX loading case [10,17,26], they were not adopted in this study. In order to obtain reliable SCF for partially overlapped CHS Kjoints, a special automatic mesh generation procedure developed by Nguyen et al [17,27,28] was employed to create well graded 3D solid finite element meshes including welding details (Fig.…”

“…Furthermore, having compared the results of overlapped and gapped CHS K-joints, Gibstein [30] Efthymiou and Durkin [29] had published some formulae but they were not adopted in the EC3 [27]. Furthermore, not many full scale testing results related to the SCF and the HSS values for partially overlapped CHS K-joints were reported [64][65][66][67][68][69].…”
