Laminated bamboo is engineered as a substitute for timber for building structures. Just as in steel structures, structural elements such as beams and columns require connecting elements. Glued-in rod (girod) is one of the connecting techniques that are being developed. The addition of a channel bracket at the glued-in rod connection is done to simplify the work method when applied to multistory building. This study aims to determine the bending behavior of the glued-in rod-channel connection. The connection flexural behavior in terms of strength, stiffness, ductility, and the type of failure. The numerical method used in this research is the finite element method. The variations used in this study are connection configurations (4 girods and 6 girods), and steel diameters (6mm; 8mm; and 10mm). From the results of the finite element analysis, the connection strength will be validated with the relevant theory. The results showed that the strength and stiffness of the 6-girod configuration was higher than that of the 4-girod configuration. The maximum strength for the 6-girod configuration with diameters of 6mm, 8mm, and 10mm are 4.22kNm, 6.45kNm, 11.85kNm, respectively. While the stiffness values for the 6-girod configuration with diameters of 6mm, 8mm, and 10mm are 154.0kNm/rad, 167.1kNm/rad, 178.7kNm/rad, respectively. Connections with a diameter of 6mm and 8mm have met the ductility requirements of SNI 1729:2020 with a ductility index of 2.38 for 6mm diameter and 4 girods, 2.06 for 6mm diameter and 6 girods, 1.63 for 8mm diameter and 4 girods, and 1.25 for 8mm diameter and 6 girods. All types of connections are classified as simple connections and non-seismic connections. The type of failure in the connection using 6mm and 8mm diameter is a steel rod fracture, while service ability failure occurs for the 10mm diameter. © 2023 American Institute of Physics Inc..
