The structural performance of Taller Timber Buildings (TTBs) heavily depends on the efficiency and reliability of connections, which play a crucial role in transferring loads, ensuring stability, and enhancing energy dissipation under dynamic actions such as seismic and wind loads. Traditional timber connections, while effective for low-rise structures, face significant limitations in TTB applications due to increased mechanical demands, potential brittle failure mechanisms and reduced energy dissipation capacity. To overcome these challenges, High-Performance Connections (HPCs) have been developed to enhance strength, stiffness, ductility and cyclic resistance. This study reviews HPC solutions across different structural systems, including timber-framed, panelized and hybrid structures. Various advanced connection techniques, such as self-centering post-tensioned joints, friction-based dissipative devices and hybrid steel-timber interfaces are analyzed to assess their mechanical properties and effectiveness in improving structural resilience. Additionally, the study discusses the key challenges associated with the adoption of HPCs, including standardization, seismic performance, long-term durability and constructability. The study contributes to advancing the design and implementation of HPCs, promoting the widespread adoption of timber as a viable material for sustainable high-rise construction.

Abstract
The structural performance of Taller Timber Buildings (TTBs) heavily depends on the efficiency and reliability of connections, which play a crucial role in transferring loads, ensuring stability, and enhancing energy dissipation under dynamic actions such as seismic and wind loads. Traditional timber connections, while effective for low-rise structures, face significant limitations in TTB applications due to increased mechanical demands, potential brittle failure mechanisms and reduced energy dissipation capacity. To overcome these challenges, High-Performance Connections (HPCs) have been developed to enhance strength, stiffness, ductility and cyclic resistance. This study reviews HPC solutions across different structural systems, including timber-framed, panelized and hybrid structures. Various advanced connection techniques, such as self-centering post-tensioned joints, friction-based dissipative devices and hybrid steel-timber interfaces are analyzed to assess their mechanical properties and effectiveness in improving structural resilience. Additionally, the study discusses the key challenges associated with the adoption of HPCs, including standardization, seismic performance, long-term durability and constructability. The study contributes to advancing the design and implementation of HPCs, promoting the widespread adoption of timber as a viable material for sustainable high-rise construction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
