Important results from the project

For enhancing our understanding of hardwood joints in timber structures, computational models for dowel-type fasteners in hardwood were developed and experimental investigations have been performed. The experimental data gave insight into the behavior under combined loading in two directions, which allowed to model the deformation and load carrying capacity of connections. Based on the models, the project proposes design equations for engineers designing hardwood joints.

Expected long term effects

Numerical models and experimental data for the prediction of the behavior of hardwood joints have been developed. The models and analytical design equations derived from a parameter study support engineers in the design of joints in structures and allow to consider nonlinear effects on the joints’ deformation and strength properties. Design models as well as characterization of material properties are prerequisites for an increased use of engineered hardwood products in the construction.

Approach and implementation

The project was a collaboration between Karlsruhe Institute of Technology (coordinator), TU Graz, LERMAB and Linnaeus University, within the ForestValue project hardwood_joint. There were regular meetings between the project partners, including industry representatives, as well as scientific exchange within and between work packages and the project partners, which led to joint publications and the implementation of research findings.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
