Department of Civil & Environmental Engineering, The University of Auckland, Private Bag 92019, Auckland, New Zealand, E-mail: j.ingham@auckland.ac.nz Abstract In order to investigate the seismic behaviour of typical New Zealand unreinforced masonry (URM) walls when subjected to out-of-plane loading, a research project was undertaken which included international collaboration between The University of Auckland, University of Adelaide and University of British Columbia in Canada. Aspects of this research project are discussed, beginning with details of the characterisation of typical New Zealand URM walls that are vulnerable to out-of-plane loading. Results of out-of-plane testing performed at the University of Auckland are presented. The testing included out-of-plane uniform static loading on a full-scale URM wall with a slenderness ratio (h/t) of 16 that had several different levels of pre-compression applied. The wall, with a height and width of 3500 mm and 1200 mm respectively, was simply supported at top and bottom and free at both ends, and behaved in an ideal one-way bending condition.
