However, several shortcomings of the traditional BRB need to be improved such as complex procedures, bad precision, too many fabricating interfaces of different materials and time consuming during the manufacturing processes. The processes in the manufacture of the traditional BRB can not assure whether the debonding material has been stuck or pasted well on the steel core and the concrete used to prevent steel core from buckling need time to develop its strength. Therefore, the fabricating quality of the traditional BRB is not easy to control and time consuming. In addition, there is no support for the steel tube in the traditional BRB to preventing sliding down during earthquakes. Furthermore, the glue material between the steel core and the debonding material will damage at high temperature and will cause sliding of the steel tube and lose its function. In this study, a multi-curved buckling restrained brace, MC-BRB, is proposed to correct abovementioned disadvantages of the traditional BRB. The component test and shaking table test of a full-scale steel structure with multi-curved buckling restrained braces were carried out to investigate its behavior and the capability for seismic mitigation. The experimental results illustrate that the MC-BRB possesses the stable mechanical behavior under cyclic loadings and provides good protection for structures from earthquake damage.
