To evaluate the displacement dependency of metallic damper which has straight type steel strut, cyclic tests are conducted with the target displacement variables on constant velocity. Form this, width to height ratio of strut is 0.079. From the strength and energy dissipation capacity comparison, cyclic test results are short of the static test results. Therefore more detailed design which are considering target structure period and dynamic characteristics is needed.
