But the seismic performance of precast concrete frames, especially with dry connections, remains a challenging issue. On the other hand, Buckling-Restrained Brace (BRB) is a special type of brace with global buckling inhibited by an appropriate restraining system, which implies a compression hysteretic behavior similar to the response exhibited under tension. Therefore, we focus on the employment of BRBs in the precast pre-stressed concrete frames. In this paper, experimental studies on a new bamboo-shape buckling-restrained brace (BBRB) are being conducted. BBRB specimens show stable and symmetric hysteretic behavior, whose cumulative plastic deformation exceeds the requirements specified in the AISC. The length of the slub mainly affects the end rotation of the segment. The longer slub provides smaller end rotation, making the segment more stable. The length of the segment served as energy dissipation part should be controlled in an appropriate range because too long segment can lead to the increase of local deformation of the segment and the decrease of low-cycle behavior.
