Finger joints subjected to tensile forces

Summary

In the first part of this paper, the main results from a series of experiments focusing on the tensile performance of finger joints are presented. Three specimens made of plywood and three specimens made of OSB were tested to evaluate their capacity and stiffness. The main failure mode observed in the plywood specimens was the delamination at the contact interface. The main failure mode in the OSB specimen was the bending/tensile failure on the external part of the joint. In the second part, analytical calculations are reported to estimate the failure load observed in the experiment.
