Round Timber Bolted Joints Reinforced with Self-Drilling Screws

Whole timber construction: A state of the art review

“…Posttensioning was used by Al-Khattat (2008) to achieve glue-free seated pipe connections. Spatial truss systems for whole timber have also been applied in tower structures (Huybers, 2002, Batchelar, 2012, Klajmonová and Lokaj, 2015. Batchelar (2012) demonstrated the use of hollow-core round timbers as structural elements in spatial trusses for telecommunications towers.…”

Large-diameter single dowel joint: finite element modelling of a reinforced joint

“…By increasing shear strength and tensile strength perpendicular to the grain in the connection area, reinforcements may reduce connection dimensions and increase load-bearing capacity and/or ductility of the joint. Many reinforcement techniques for such connections have already been proposed, such as glued-on wood-based panels (Blass and Schälde 2011), fibreglass (Soltis, Ross and Windorski 1998;Chen 1999), nail plates (Hockey, Lam and Prion 2000;Mastschuch 2000), threaded rods and glued-in-rods (Quenneville and Mohammad 2000;Steiger et al 2015), textiles (Haller and Birk 2006) or self-tapping screws (Hansen 2002;Bejtka and Blass 2005;Kobel 2011;Lathuillière, Bléron, Descamps and Bocquet 2015;Klajmonova and Lokaj 2015).…”
