failure in timber structures occurs mainly in crucial points such as joints areas. therefore, the idea of using composite sheets in timber joints has been intro-duced as a method in order to increase the strength and ductility behaviour of timber joints. this research aims to study the behaviour of bolted joints in poplar and pine woods, which are reinforced by two types of gfrp sheets. a singl...

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...

In contrast to nailed connections, little research has been done on bolted connections using a reversed cyclic loading scheme, although cyclic loading provides important information about energy absorption and damping properties, which is essential when analyzing seismic performance. Dowrick (1986) noted that the hysteretic characteristics for the primary connection of a subassembly govern its ...

Abstract The management of axial forces is an important issue when a joining method that takes into account the generated by tightening bolts applied to bolted joints wooden structure during construction. This study focuses on elastic interactions in which force adjacent changes as result sequential each bolt multiple affecting deformation around other bolts. To this end, experiments are conduc...

In this research, the effects of torque tightening on the stress distribution in double lap simple bolted and hybrid (bolted-bonded) joints have been investigated numerically. In order to determine the bolt clamping force value due to tightening torque in simple bolted and hybrid joints, which is necessary in numerical simulation, an experimental approach has been proposed. To do so, two kinds ...

As a renewable building material with low embodied energy characteristics, wood has gained more and more attention in the green and sustainable building industry. In terms of material resource and physical properties, scrimber composite not only makes full use of fast-growing wood species, but also has better mechanical performance and less inherent variability than natural wood material. In th...
