ABSTRACT

Self-centering Friction Damping Brace (SFDB) and performed tests accordingly. Miller et al. (2011) connected stranded SMA wires to ordinary cables to provide the restoring force, utilized them in the mild steel energy-dissipative buckling-restrained brace with three-layer steel pipes to make a new type of the Self-Centering Buckling-Restrained Brace (SC-BRB), and conducted pseudo-static testing on a large-scaled specimen thereof. Liu et al (2012) placed an energy-dissipative mild steel into the above-mentioned specimen and below gaps between inner and outer steel pipes of equal length, allowed pre-stressed strands to pass through the inner and outer steel pipes and fixed them on both ends of the steel pipes to create a novel type of SelfCentering Buckling-Restrained Brace (SCBRB), and then tested its seismic performance via pseudostatic testing. Chen et  al. (2014) proposed three kinds of large sizes of the self-centering brace based on SMA bars or plates, and gave the brief description to the construction. The author (2016) summarizes the advantages and disadvantages of currently research about the re-centering function brace, and points out the key problems needed to study in the future.
