摘要
采用大型有限元程序ANSYS分析了Pall型摩擦阻尼器(PFD)的滞回性能,证明了Pall摩擦阻尼器和改进的Pall摩擦阻尼器—T形芯板摩擦阻尼器(TFD)的力学特性是相同的.采用AN-SYS程序对安装Pall型摩擦阻尼器的钢框架和钢筋混凝土框架进行了有限元分析,分析结果表明安装Pall型摩擦阻尼器能有效提高结构的刚度,并且大大提高框架的耗能能力.
Abstract：Force analyses using the commercially available ANSYS program show that the resisting forces generated by the T-shaped core plate frictional damper （TFD） and Pall frictional damper （PFD） are i- dentical with identical frictional forces considering geometric nonlinearity. The steel frame and concrete frame with Pall-typed frictional dampers are analyzed by ANSYS program. The analysis results show that the energy dissipation capacity of structures with Pall dampers is enhanced significantly.
