In the past study, authors have conducted the fatigue performance tests of the buckling-restrained braces using high-performance type and the basic-type specimens, and discussed the fatigue performance in the large plastic-strain amplitude.
In this paper, the fatigue performance tests of the buckling-restrained braces are carried out in the small-plastic strain amplitude. The linear relations from the small plastic-strain amplitude to large plastic-strain amplitudes of the buckling-restrained braces have been shown on a logarithmic scale from the test results. The fatigue performance of the buckling-restrained braces is able to be evaluated on the basis of these relations.
