Buckling-restrained braces with replaceable fuses:an experimental investigation
This paper develops a new type of Buckling-Restrained Brace(BRB)with replaceable steel angle fuses.The proposed BRB provides the ease of post-earthquake examination on fuse damages,the convenient and prompt replacement of damaged fuses and the re-use of the buckling restraining elements while maintaining the other positive features of ordinary BRBs.To explore seismic behavior of the proposed BRB,several specimens were tested.The test parameters varied in these specimens included fuse design,debonding material and loading protocol.Test results show that the proposed BRB can exhibit stable hysteretic behavior up to fairly high fuse strain levels.Failure modes of the specimens were found to be ruptures of the angle fuses as expected.The compression strength adjustment factors and the cumulative plastic deformations of the specimens satisfy the requirements specified by AISC 341-16.Moreover,the research showed that fuse replacement is convenient and prompt.The repaired specimens behaved satisfactorily in the following test.
