Authors have devised a seismic response control brace composed of an ordinary axial force member as intermediate member and two the axial hysteresis dampers at its both ends, which is available for industrial frame structures having longer diagonal braces. In the former paper Part 1, the buckling restraint conditions of the brace with the dampers were formulated by developing the beam-column theory. In this paper Part 2, loading tests on six types of the whole brace models are carried out, and the adequacy of the buckling restraint condition theory is verified. And then the cyclic loading tests on the axial hysteresis damper, which consists of the cruciform steel core and the rectangular buckling restraint tube are carried out, so that the accumulative plastic deformation capacity as well the cyclic hysteresis load and deformation relation is discussed.
