［摘要］对采用金属屈服阻尼器进行框架结构等效线性化分析中阻尼器变形的取值进行了讨论。通过理论分析和有限元实例，验证了梁的弯曲变形对阻尼器变形的影响，推导了可在工程中采用的阻尼器位移折减系数取值简化计算方法。最后通过一个6层框架结构的减震分析，验证了所提出的位移折减系数取值方法的准确性和实用性。

Abstract:The value of the deformation of the damper in the equivalent linearization analysis of frame structure with metallic yield damper was discussed. Through theoretical analysis and finite element analysis, the influence of the bending deformation of the beam on the deformation of the damper was verified, and a simplified calculation method for the displacement reduction factor of damper in the engineering was derived. Finally, the accuracy and practicability of the proposed displacement reduction coefficient calculation method were verified by energy dissipation analysis of a 6-story frame structure.

Keywords:metallic damper; damper deformation; FEM analysis; elasto-plastic  time-history analysis
