Study of Properties of Mixed Steel Yielding-Friction Energy Dissipators

In this paper, a new idea of energy dissipator design that different energydissipating mechanisms can be utilized comprehensively in the same kind of energy dissipatorsis put forward. Based on this idea, the mixed steel yielding-friction energy dissipator(MSYFED) is invented by the authors . The property experiment of MSYFED and the comparativeexperiment of MSYFEDs, steel circular ring energy dissipator and friction element under lowcyclic reversed loading are conducted. The working and energy dissipating behaviors areinvestigated and the restoring model of MSYFEDs are set up. The experimental results show that MSYFEDs can dissipate a great deal of energy by yielding of steel circular ring and fric-tion of steel or steel and bronze. The working and hysteretic behaviors are stable and thecapacities of load bearing and energy dissipating can be easily adjusted. MSYFEDs arecompact in shape, small in volume, simple in construction and cheep in cost. It can be in-stalled. removed and replaced conveniently and easily. Its application prospect appears to behighly promising.
