CLT (Cross-Laminated Timber) panels represent one of the most used technologies for wooden structures. The design and the details of panel-to-panel connections represent an aspect of utmost importance to understand the overall behavior of timber structures subject to lateral loads, such as seismic loads. For these reasons, new solutions for connections have been -and continue to be- proposed in the last years. In this framing of research, this paper proposes a new type of dissipative steel connection for timber structures. As an alternative to traditional solutions, such as hold-down and angle brackets, this connection is conceived to be easy to fabricate and to be installed, allowing, moreover, the use of a small number of connectors. Different joint-panel model combinations are presented, and numerical analyses are carried out to study the behavior of CLT panels equipped with the proposed connection under lateral load. The performed FEM analyses lead to the identification of two innovative optimized solutions of connections, recently patented by the authors, which will be prototyped in the next future.

Abstract
CLT (Cross-Laminated Timber) panels represent one of the most used technologies for wooden structures. The design and the details of panel-to-panel connections represent an aspect of utmost importance to understand the overall behavior of timber structures subject to lateral loads, such as seismic loads. For these reasons, new solutions for connections have been -and continue to be- proposed in the last years. In this framing of research, this paper proposes a new type of dissipative steel connection for timber structures. As an alternative to traditional solutions, such as hold-down and angle brackets, this connection is conceived to be easy to fabricate and to be installed, allowing, moreover, the use of a small number of connectors. Different joint-panel model combinations are presented, and numerical analyses are carried out to study the behavior of CLT panels equipped with the proposed connection under lateral load. The performed FEM analyses lead to the identification of two innovative optimized solutions of connections, recently patented by the authors, which will be prototyped in the next future.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
