چکیده
Cross-laminated timber (CLT) is increasingly being used in lateral load resisting systems of multi-storey buildings. Conventional in-plane CLT shear walls can be transformed into core-wall structures with enhanced strength and stiffness when the individual are connected orthogonally. In this paper, experimental studies presented on orthogonal joints self-tapping screws (STS) installed mixed angles, i.e. different installation angles between STS axis plane surface. A total 59 joint specimens were tested 9 configurations to derive relevant performance parameters from monotonic cyclic tests. The five-layer seven-layer panels by ?8 mm or ?12 STS. Different ratios inclined at 90° surface investigated determine an optimum ratio for performance. It was found that a one every two ensured significant increase ductility displacement capacity approximately three times compared only minimum moderate achieved all test series where primary failure mode withdrawal. contributed both also contained average overstrength 1.7 most configurations. Existing analytical models adequate estimating but inadequate estimate stiffness.

Bolted Timber Joints with Self-tapping Screws
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 reinforc...

The use of self-tapping screws with continuous threads as a reinforcement to avoid splitting of members in connections with dowel-type fasteners was studied in two projects carried out at the Universities of Nottingham and Karlsruhe. The reinforced specimens showed a very ductile failure mode whereas the non-reinforced specimens failed in a brittle way. Although the reinforced specimens also sh...
