摘　　要：针对防屈曲支撑整体稳定和局部稳定性条件,结合钢结构稳定理论对防屈曲支撑整体稳定性和芯材的局部稳定性进行了理论分析和推导,提出了相应的计算公式,并进一步提出了防屈曲支撑芯材的屈服段与约束试件之间的局部挤压力计算公式。结合所建议的计算公式,可以对防屈曲支撑整体稳定性和芯材局部稳定进行验算和分析。To study the global and local stability of buckling restrained braces（ BRBs）,based on the theory of stability of steel structure,the theoretical analysis and derivation of the global and local stability of BRBs were conducted and the calculation formula was put forward. Furthermore,the calculation formula of local extrusion force between the yielding segment of core steel and the constraint component was proposed. The calculation and analysis of the global and local stability of BRBs can be achieved according to the suggested calculation formula.
