Development of Resilient Seismic Solutions for Timber Structures in New Zealand Using Innovative Connections
There is increasing public pressure for damage avoidance structural systems using new engineered wood products, especially cross-laminated timber (CLT), in countries with high levels of seismic activity, such as New Zealand, to minimise the destruction after severe earthquakes with no post-event maintenance. This study presents damage avoidance lateral load-resisting systems (LLRSs) using rocking timber panels and the innovative resilient slip friction joint (RSFJ) technology. RSFJs can be used as hold-downs or as ductile links between adjacent walls or between the walls and boundary columns. These joints are capable of providing a self-centring behaviour (the main deficiency of conventional friction joints) in addition to a high rate of energy dissipation, all in one compact package. In addition, a novel type of shear-transferring device is introduced to be used as the shear key for rocking structural members. The proposed concepts are described and verified by large-scale experimental tests and numerical simulations. The results confirm that the introduced systems can be considered as the new generation of resilient LLRSs for timber construction.
