摘要
对设置两种新型摩擦阻尼器(T形芯板摩擦阻尼器和拟粘滞摩擦阻尼器)和粘滞阻尼器的单自由度结构及多层实际工程结构进行了时程分析研究。结果表明,一方面三种阻尼器都能有效地控制结构的反应,另一方面T形芯板摩擦阻尼器的位移控制效果略好于拟粘滞摩擦阻尼器,但是后者的加速度控制效果好于前者。
Seismic performance of the SDOD and MDOF structures incorporating two types of frictional dampers and viscous damper are studied by using time history analysis method. The analysis results show that all three types of dampers can control response of structure efficiently, and T-shaped core plate frictional dampers(TFDs) possess better displacement control effects than pseudo-viscous frictional dampers(PVFDs), but, PVFDs have better acceleration control effects than TFDs.
