The influence of yielding displacement of friction energy dissipating devices on suppressive effectiveness of structure vibration

摩擦耗能支撑减震技术是一种行之有效的减震措施,本文利用ANSYS分析了耗能器屈服位移对结构减震效果的影响,得出对于本文算例耗能器屈服位移取为结构层屈服位移的0.18～0.45时,减震效果最好。

Friction energy dissipating bracing is the kind of efficient system on vibration - suppressing of buildings. In this paper, the influence of yielding displacement of friction energy dissipating devices on suppressive effectiveness of structure vibration is studied by ANSYS finite element program. The vibration-suppressing effect is much better when yielding displacement of the dissipater is from 0.18 to 0.45 as that of the structure layer.
