［摘要］對采用金屬屈服阻尼器進行框架結(jié)構(gòu)等效線性化分析中阻尼器變形的取值進行了討論。通過理論分析和有限元實例，驗證了梁的彎曲變形對阻尼器變形的影響，推導了可在工程中采用的阻尼器位移折減系數(shù)取值簡化計算方法。最后通過一個6層框架結(jié)構(gòu)的減震分析，驗證了所提出的位移折減系數(shù)取值方法的準確性和實用性。

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
