Abstract
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.
