Experiment and Finite Element Analysis on the Ultimate Strength of Ring-Stiffened Tube-Gusset Joints
Abstract Adding ring-stiffeners is an effective strategy for strengthening CHS tubular joints. However, research on the capacity of ring-stiffened CHS tube-gusset joints remains limited. In this study, we performed experimental and numerical analyses to derive static strength equations for this joint. For convenience, we simplified the complex joint model into a ring plate to CHS joint, which consisted of a CHS tube and a ring-stiffener. First, we tested five specimens to obtain failure mode and ultimate strength. Second, a finite element model was established and validated by the experimental results. Then, we used the verified numerical method to simulate the behavior of the ring plate to CHS joint. A wide range of geometric parameters was considered, and the relevant design guide was assessed. Finally, nonlinear analysis was performed, and a design formula was proposed. Good agreement was achieved between the proposed design formula and the results of experimental and numerical analyses.
