This research presents two methods to prevent local buckling from circular tube brace and then verify their performance capacity through a cyclic loading test. As control methods on local buckling, one is to restrict local buckling as attaching cover plate at range of buckling. And the another is to exclude danger of buckling as inserting contraction device with rod and spring at the center of brace. The purpose of this research is to develop structural device for restriction of local buckling or for exclusion of its. And we investigate appliance of suggested methods through an experiment. We also estimate the improvement of performance capacity in a quantitative respect.
