Abstract
ECHAVARRIA, César. BOLTED TIMBER JOINTS WITH SELF-TAPPING SCREWS. Rev.EIA.Esc.Ing.Antioq [online]. 2007, n.8, pp.37-47. ISSN 1794-1237.
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 screws. Laboratory experiments on reinforced and non-reinforced timber joints with 15,9-mm bolts have shown good agreement with the model predictions.
Keywords : timber joints; brittle failure mode; reinforcement perpendicular-to-grain; analytical model.
