Seismic reduction and control analysis of frame structure with viscous fluid dampers

为研究框架结构装设黏滞流体阻尼器减震效果,以某钢筋混凝土框架结构为背景,考虑采用装设黏滞流体阻尼器的减震控制方法,输入地震波进行时程分析,同时对比减震结构和非减震结构的抗震性能。分析结果表明,与非减震结构相比,装设黏滞流体阻尼器的结构减震效果明显,阻尼器在不同工况下滞回曲线均匀饱满,呈现典型非线性速度阻尼器特征,分析结果对于黏滞流体阻尼器的应用与推广具有一定的参考价值。

In order to study the effect of seismic reduction of frame structures with viscous fluid dampers,with a reinforced concrete frame structure as the background,consider using a vibration control method with viscous fluid dampers,seismic waves are input to the structure for time history analysis,the seismic performance comparison of damping structure and non damping structure. The analysis results show that,compared with the non damping structure,structure damping effect of a viscous fluid damper,damper under different working conditions of hysteretic curve of full uniform,showing the typical characteristics of damper nonlinear velocity,the results have some reference value for the application and promotion of viscous fluid dampers.
