Abstract

The aim of this article is to demonstrate the potential of using shape memory alloy (SMA) as a dowel in timber connection to provide a recenterable effect and higher energy dissipation capacity. Two dowel-type timber connections were fabricated for double shear tests under cyclic loadings. The results not only showed that the timber connection with SMA dowel has a good recentering effect, but also has a higher energy dissipation capacity that will outperform the steel-doweled connection in the long term and constant vibration in structures. This article also calls for the need to investigate how this system can be used in conjunction with normal steel dowels and to develop a stronger SMA to satisfy the strength and stiffness requirements of timber connections.
