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

Mechanical Properties of Glulam Moment-Resisting Joints Reinforced by Inclined Self-Tapping Screws
BioResourcesSelf-tapping screws (STS) are an effective fastener to enhance wooden moment-resisting joints. However, the effects of the arrangement and insertion angle of STS on the mechanical properties of wooden joints are less studied.

Design concept for CLT - reinforced with self-tapping screws
, 2013 Concentrated loads on Cross Laminated Timber elements (CLT) in areas of point supports or load applications cause high local shear stresses. Inclined self -tapping screws with continuous threads have turned out to be an effective reinforcement. As neither the German design standard DIN 1052 [2] nor technical approvals cover this construction method a ...
