The paper describes the preliminary phase of an experimental investigation into the behaviour of reinforced masonry shear wall elements subjected to high speed cyclic loading. The three specimens tested in the preliminary phase were full scale wall panels about 4 meters square, each consisting of two piers connected by a top and bottom spandrel; each panel was made from a different material. The results of the tests on the three specimens are presented in the form of dynamic force deflection relationships. The test equipment designed for the program is described in detail, and the next phase of the test program is outlined.
