ABSTRACT

The stiffness of the glued-in rod is a highly important property since most timber structures are statically indeterminate structures. Hence, stiffness of connections in timber frames has a large influence on the static scheme of the structure, and therefore on the distribution of stresses within the timber truss. Being able to predict stiffness of glued-in rods interventions can avoid damaging changes in the static scheme of historical trusses which could induce cracks and damage the whole structure. The comparison concerns the stiffness and the strength of the glued-in rods. From a stiffness point of view, the model can also predict quite accurately the behaviour of the modelled glued-in rods. A glued-in rod, or bonded-in rod, is a bar glued into a piece of wood, which is used as a connector in new structures, a repair in old damaged buildings or a piece of reinforcement in existing structural members.
