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...
متن کاملExperiments on dowel-type timber connections
Dowel-type connections are commonly used in timber engineering for a large range of structural applications. The current generation of design rules is largely based on empiricism and testing and lacks in many parts a stringent mechanical foundation. This often blocks an optimized use of the connections, which is essential for the design of economically efficient structures. Moreover, it severel...
متن کاملSelf-tapping Screws as Reinforcement Perpendicular to the Grain in Timber Connections
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...
متن کاملStrain and Damage Sensing Property of Self-compacting Concrete Reinforced with Carbon Fibers
Present paper investigated the strain and damage sensing property on concrete cubes embedded with carbon fibers. Concrete cubes of dimension 150 mm have been casted with different concentration of carbon fibers to study the strain and damage sensing property under cyclic loading that can be further used for health monitoring as non-destructive testing (NDT) approach. All the specimens were test...
متن کاملLoad-carrying behaviour of steel-to-timber dowel connections
This paper details tests on steel-wood-steel connections with thin dowels carried out at the University of British Columbia in Vancouver, Canada. Connections configurations were selected in such a way that the influence of the main parameters such as dowel slenderness ratio, dowel strength, fastener spacing and end distance and the number of dowels could be studied. An important issue of the pa...
