The woody structural elements represent a significant portion of old works and historical buildings,and the need for retrofit and strengthening them increases.Glued-in rods are an efficient way of providing stiff,high-capacity connections in timber structures.Those flexible joint systems have the advantages of high load transition,appropriate behavior in case of fire,easy application combined with a high level of prefabrication for fast installation.Besides,the aesthetic appearance of the finished joint also plays an important role.Many experiments were undertaken on this subject in Europe,but a common database about the designing instructions of glued-in rods was never encouraged.This paper aims at summarizing the different factors that can affect repairs made with glued-in rods and their influence on said repairs. 展开更多
