It is now widely recognized that the performance of non-structural elements is crucial to the performance of building systems during earthquakes.

Field surveys and experimental studies have shown that light steel or timber framed plasterboard partition walls are particularly vulnerable.

The objective of this study is to investigate the seismic performance of a novel seismic gap partition system with angled return walls under quasi-static cyclic

loading applied obliquely and to investigate the benefits of using acrylic gap-filler in the seismic gaps.
