Fastening in Timber Structures: Performance Assessment of Glued-in Rod Connections

The use of biobased materials as timber, known for their carbon sink potential, marks a change in the construction field. In this way, the glued-in rod connection (GiR) is emerging because of its high mechanical properties and esthetic. However, the lack of standards makes its use confidential. This work aims to have a better understanding of the use and design of the GiR connection in France. A state of the art and an analysis of the professional uses were conducted to enlighten the research and practical aspects of this fastening. Relevant case studies were studied to analyze the standard design methods. The outputs underline the current monopolistic expertise of one manufacturer. Even though the opening of new markets for GiR thanks to the entry in the new version of Eurocode 5, the high cost and the specific expertise may curb their development.
