N2 - This paper discusses the recently conducted shake-table tests of an unreinforced masonry building retrofitted according to current standards and practice in the US. The test structure, designed to represent existing structures, was a single-story double-wythe URM building with a 6.9 m by 2.6 m plan view and height of 3.7 m. It included openings, a timber roof diaphragm, and a parapet. The retrofit system included postinstalled anchors and steel strong backs. The retrofitted building system was instrumented with an array of 170 sensors, and it was subjected to a sequence of bi-directional ground motions of increasing intensity. The structure was able to resist, without any visible damage, the ground motions up to the design level earthquake. However, the structure was severely damaged in the following test that corresponded to a ground motion between the design level and the maximum considered earthquake. The design details of the retrofit design are discussed in the paper which also provides insight into the behaviour and brittle failure mechanism of the test structure.
