The authers reported on the testing of some buckling-restrained braces that use different buckling restraining methods, and also discussed their performance evaluation. In consideration of the advantages and drawbacks of the results from testing and manufacturing, a new type of buckling-restrained brace is conceived through the use of new manufacturing methods. A partial frame model of the structure with the buckling-restrained brace is used as the test equipment, and static cyclic loading testing is conducted by applying increasing loads alternately in positive and negative directions. The cumulative ductility factor, the energy absorption rate, and the final facture characteristics of the newly buckling-restrained braces are analyzed.
