In order to examine hysteresis behavior of the brace-type frictional damper, cyclic loading test were carried out. The brace-type friction damper consists of a brace part and a friction damper part to prevent buckling occurring in the brace structure. In the test of the amplitude input waveform, the friction dampers showed stable hysteresis behavior from the 1-cycle to the last 15-cycle, and sufficient energy dissipation occurred. It has been shown that a constant level of frictional strength is secured during three times of the cyclic loading test in the incremental amplitude input waveform and the brace type friction damper can be reused only by replacing the friction material after the earthquake.
