Abstract

Abstract

The double-T-shaped innovative buckling-restrained brace is a new kind of energy-dissipation brace，so the factors affecting its performance are to be numerous． In order to study the influence of the buckling-restrained mechanism，the buckling restraining ratio， defined as the ratio of Euler load of the outer buckling-restrained mechanism to the yielding load of the steel core，width to thickness ratio of the steel core，the incising mode of the steel core etc lon the energy-dissipation capability of the brace，low cyclic loading tests were conducted on six reduced scale brace specimens． The destruction modality， the hysteretic behavior， energy-dissipation， the displacement ductibility，the rigidity degeneration etc of the innovative brace were studied． The test study demonstrates that the joint of the buckling-restrained mechanism and the steel core of this innovative brace is reliable，and the influence of the buckling-restrained mechanism and the buckling restraining ratio is obvious among all the examined factors，and then the brace with rational composition has a full hysteretic loop， stable energy-dissipation behavior， better displacement ductibility，slower rigidity degeneration．
