The authors have proposed new concept of split-tee connections at bottom flanges of beam ends, which work as beam-end elasto-plastic dampers. They are composed of small buckling-restrained axial members, and their cumulative deformation capacities or energy dissipating capacities are one of the most important indexes for such members' performance, because they are used under very high strained cyclic loadings. In this paper, cyclic loading tests are carried out for beam-end dampers, and their performances against low-cycle fatigue are examined. Their cumulative deformation capacity under random inputs are also evaluated with the proposed method and compared with those of buckling restrained braces.
