Probably the simplest devices are based on yielding and hysteresis of metallic elements. This paper presents experimental work on a recently proposed mild steel shear panel hysteretic device. Its stability, low-cycle fatigue life and dissipative capacity are explored. Thermal imaging is used to view the energy flow through a cyclic test to destruction. Hysteretic capacity and low-cycle fatigue life are determined through a series of cyclic tests at constant strain amplitude. Finally, the performance of the device under repeated seismic loading is evaluated using the real-time hybrid technique, in which the test on the device is coupled to a numerical simulation of a surrounding structure. The device is shown to have great potential as a seismic energy absorber. Suggestions are made to improve the device through the use of alternative materials in place of steel.
