介绍了近年来各国学者提出的几种装配式防屈曲支撑形式；在此基础上，阐述了内核构件与外围约束构件的相互作用机理，外围约束构件刚度折减等装配式防屈曲支撑设计理论问题；讨论了保证外围约束构件整体工作对螺栓强度和螺栓间距的要求；最后对防屈曲支撑框架节点性能的研究现状进行了总结。

英文摘要：

Several types of assembled buckling-restrained brace （ABRB） proposed in recent years were introduced. Then, the design theories of ABRB, such as the complicated interaction mechanism between the inner core and outer restraining components, as well as the stiffness reduction of outer restraining components were reviewed. Design requirements on the strength and distance of bolts were discussed in detail. Finally, the research achievements on the behaviors of joints in buckling-restrained brace frame （BRBF） were summarized.
