Abstract
ABSTRACT This paper reports the seismic performance of two ‘rocking’ internal plasterboard partition wall specimens comprising dual-slot tracks (DST) with a) sacrificial L-trim (SLT) joints and b) boxed end-studs and standard plastered joints investigated under quasi-static cyclic drift demands. The top gap between the top DST and the wall allows it to rock up to the desired level of inter-story drift. The SLT joints between adjacent plasterboard panels failed after the top gap in the DST was exhausted. The plaster cracks in the joints between the in-plane and out-of-plane plasterboard panels occurred early at 0.20% drift. However, the ‘rocking’ specimen with boxed end-studs exhibited a comparable seismic resilience to partition walls with horizontal seismic gap widths along the partition wall indicating that these gaps can be significantly reduced when the wall is allowed to rock using the DST details for the same inter-story drift capacities.
