Research status of glued-in rods connections in wood structures

Glued-in rods connections are widely used as a post-anchoring reinforcement technique in timber structures. The rods are inserted into boreholes with adhesive and then cured to form a whole with high strength, stiffness, and aesthetic properties. Although the glued-in-bar connections have been applied successfully, there are still some problems in the research of these connections in wood structures. There is still no unified standard for glued-in connections in wood structures. In this paper, the state of the art in glued-in-rod connections in wood structures is presented, the main influencing factors, failure modes glued-in rod, and the design methods of glued-in rod con-nections are summarized. The study provides a reference to bonded bar connections and the de-velopment of recommended design methods glued-in rod.
