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.
