Self-tapping screws as reinforcement for timber structures

, 2009
Modern self-tapping and continuously-threaded woodscrews enable new methods for strengthening and joining timber and glulam construction elements. As these screws have a high axial strength and an excellent continuous bond to the wood they can be used similar to steel reinforcement in concrete construction.

Modeling of torque for screw insertion process [PDF]

, 2006
A self-tapping screw is a high-strength one-piece fastener that is driven into preformed holes. We analyze and improve a mathematical model of the self-tapping screw insertion process so that it can be used in manufacturing processes at the Bose ...

Influence of screw angle and position on the extraction dynamics of Cross-Laminated Timber: an empirical analysis and comparative modeling study

Journal of Asian Architecture and Building Engineering
The design of dowel-type fastener connections is crucial for the structural integrity of Cross-Laminated Timber (CLT) systems, with individual fastener anchorage capacity as a key factor. This study investigates the withdrawal performance of Self-Tapping

BOLTED TIMBER JOINTS WITH SELF-TAPPING SCREWS

Revista EIA, 2007
The use of self-tapping screws with continuous threads in the joint area as a reinforcement to avoid splitting of timber members is studied. A theoretical model is developed to calculate the stress distribution around a pin-loaded hole in a timber joint, to predict brittle failure modes in bolted connections and to calculate the load in the reinforcing

Reinforcement of Timber Dowel-Type Connections Using Self-Tapping Screws and the Influence of Thread Configurations [PDF]

The application of self-tapping screws as reinforcement on glulam connections has been proven effective. However, the implication of different thread configurations on the effectiveness of reinforcement remains unknown.
