Requirements On Ductility In Timber Structures

The aim of this paper is to give a first approach of a mechanical model, to predict the behavior of semi-rigid joints in timber structures with the focus on the bearing capacity and the rotation capacity. Experiments have been conducted to identify the load-deflection behavior of selected dowel arrangements and to verify the mechanical model. In a second step the model has been simplified to give an approach for the practical application. In addition the attention is given to the material scattering of timber. A computer model has been developed to determine the variation of the beam end rotations caused by the scattering of the modulus of elasticity. To ensure that a ductile behavior of the joint takes place before a brittle member fails, …
