Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


The use of self-tapping screws is a state-of-the-art practice in fastener and reinforcement technologies for timber structures. The high axial stiffness and load-carrying capacity of self-tapping screws, together with their easy handling, make them one of the most economical choices for applications in both fastener and reinforcement domains. This chapter focuses on mechanical models for timber members reinforced with self-tapping screws and the material properties of self-tapping screws and screwed-in threaded rods. Furthermore, the behaviour of reinforced timber members under shrinkage is discussed.
