Abstract: The joints connecting vertical and
horizontal elements are the ˇ°weak linkˇ± in structural systems assembled from
wood panels. If they are too weak, local failures may occur, resulting in
performance that is significantly below expectations. If they are too resistant,
the joints may be unable to dissipate energy during vibrations, thus possibly
initiating a fast progressive failure. This paper re-processes and re-elaborates
the results of shaking table tests previously carried out by the author and
other co-workers. The goal is to assess the feasibility of a joint which is able
to dissipate energy during vibration, without degrading the connection
performance.
