Abstract:
Six single-storey unbonded post-tensioned concrete masonry (PCM) walls were tested on a single dimension shake table at North Carolina State University. The principal intent of this study was to validate the use of PCM for residential construction, before the first PCM house is built in New Zealand. Three rectangular walls were tested to demonstrate the seismic performance of post-tensioned rocking walls, followed by walls containing a door and window opening and a shrinkage control joint. A detailed account of wall construction, test setup, testing procedure and test results are provided in this paper.
