“…The FE model matched well with the experimental results. Sitong et al [30] proved that the proposed analytical model could accurately predict the distributed load of every ring stiffener at the tube-gusset joint with errors never exceeding 5%. In the 4…”

“…Compared with fatigue analysis, the influence of welds on the accuracy of static analysis is relatively small [2,33,34]. Qu et al [26] and Sitong et al [30] used the shell281 element to model the tube-gusset joints in their research but did not establish a weld model. The accuracy of the FE model was evaluated by comparing its results with the test results, including the failure mode, strain-load relationship, and load-displacement curve.…”

“…Comparisons between the mechanical properties of the KK-type and K-type joints were also presented [29]. Sitong et al [30] investigated an analytical model for the load distribution in multiple-ringstiffened tube-gusset joints, whereas Chen et al [31] studied the application of ring plates in tubular joints. In general, 1/4 ring plates are primarily used in K-type or KK-type joints, and full-ring plates are generally used in X-type joints.…”

This study aims to investigate the effect of the ring plate on the mechanical performance of X-type tube-gusset joints. The failure modes, ultimate strengths, and failure mechanisms of X-joints with ring plates were investigated through experiments and finite element analyses. The results indicated that the ring plate and the chord within the effective range of the ring plate constituted the primary bearing structure of the X-joint. Increases in the ring plate thickness and width increased the ultimate strength of the X-joint. By considering the forces of the braces as a superposition of the bending moment and the force acting on the gusset of the X-joint, a simplified calculation method for the ultimate strength of X-joints was established. The derivation process was validated and refined through experiments and finite element analyses. Finally, a safe and reliable formula was derived for evaluating the ultimate strength of X-joints.
