摘要
研究了带有金属阻尼器及其与粘滞流体阻尼器串并联组合平面框架体系。分别采用Bouc-Wen模型和粘滞阻尼模型模拟金属和粘性流体阻尼器的滞回特性,建立耗能体系的动力分析方法。数值分析表明,阻尼器采用并联组合方式对位移和加速度的减振效果要优于串联组合方式。
The effects of reducing seismic response of two-combination energy dissipation system, which arranged a viscous fluid damper and a metallic damper in series and in parallel, were investigated in the paper. The hysteretic characteristics of the two dampers were described by viscous damping modal and Bouc-Wen differential model respectively, and then the dynamic analysis method of energy dissipation frame system was established, Numerical analysis showed that dampers in parallel could obtain better vibration reduction effect in displacement and acceleration response than those in series.
