The resistance of a structure against an earthquake is related to its ability to absorb the seismic input energy. The development of devices for dissipating the seismically induced energy on the structure is a subject that is receiving large attention in the field of earthquake engineering. One example of these devices is the steel plate with slits. In this paper, the ultimate energy absorption capacity of slit plates subjected to shearing deformations is investigated experimentally. The parameters involved on the tests are the aspect ratio of the struts that form the plate (B/H), the material (mild steel, high strength steel) and the loading pattern. The hysteretic curves are decomposed into the skeleton part and the Bauschinger part. The ultimate energy absorption capacity is the sum of the energy dissipated on the skeleton and that on the Bauschinger part. As a result, it is shown that the energy attained by the skeleton part can be analytically predicted and that attained by the Bauschinger part can be estimated empirically.
