The dynamic behavior of an unreinforced masonry wall is investigated through a shaking table test of two specimens. In order to represent a non-engineering one-story house, the first specimen consists of a Cshaped structure with masonry walls connected only at their ends. The second specimen is built to represent an upper story, so the C wall is connected at the top by a wooden diaphragm floor, and a weight is suspended onto it. The test results show each specimen exhibits different behaviors. In the first specimen, an out-of-plane failure mode governs. In the second specimen, a shear failure mode governs.
