ABSTRACT
Most of the research considering out-of-plane seismic assessment of URM walls has been conducted using laboratory-based studies with artificial boundary conditions. Thus, in-situ testing is required to provide data with which to validate the accuracy of laboratory-based studies of out-of-plane walls. An in-situ testing program was developed by performing airbag tests on 2 non-load bearing partition walls of the William Weir Wing of Weir House in the city of Wellington, New Zealand. The 3 storey building was constructed in 1932 and is comprised of reinforced concrete perimeter walls with cement plaster and terracotta masonry interior facing with unreinforced terracotta masonry partition walls. One wall was tested in the as-built condition and the second wall was retrofitted with Carbon Fibre Reinforced Polymers (CFRP) using the Near Surface Mounting (NSM) technique. The pseudo-static tests were performed on the surface of the 1-leaf clay brick terracotta masonry walls by applying uniform pressure. The test walls, having dimensions of 3600 mm by 4100 mm, were supported at four sides and acted in a two-way bending mode. The test procedure and measured strength and stiffness properties of the two walls are presented.
