- Description
- Historical unreinforced masonry (URM) buildings in Australia are vulnerable to damage during earthquakes. This was highlighted by the 1989 Newcastle earthquake, which caused extensive damage in older URM construction, despite being of only moderate magnitude (M5.6). Based on the importance of the historical URM buildings, this study was conducted to investigate the global in-plane behavior of the old URM walls by placing emphasis on both the pier and spandrel geometry, whereas previous testing considered only the performance of the piers. Experimental pseudo-static cyclic in-plane testing of walls which represent old Australian unreinforced masonry construction was conducted to assess the in-plane shear behavior by investigating the shear strength, failure behavior, ductility and displacement capacity. The ongoing testing program consists of eight full-scale perforated wall specimens with arched openings. The walls are 2630 mm long, 2400 mm high with a two-leaf thickness of 230 mm using American or common bond. Two different geometries are considered by varying the spandrel depth and two levels of vertical pre-compression stress were selected. In this paper, the results are presented for those walls already tested, consisting of the first four walls (shallow spandrel geometry) of the eight-wall experimental program. The test results show a significant effect of the pre-compression load on the load-displacement behavior and the failure mode of the walls. Also, the results show that for the same configuration of the walls, the failure mode varied between specimens.
