| 摘 要： | 首次提出了Pall型摩擦阻尼器适用于不规则框架新型安装方式,按常规将阻尼器放置在框架中心。以等腰梯形框架结构为例,考虑几何非线性对安装Pall型摩擦阻尼器的不同坡度的该框架进行了详细的有限元分析,采用ANSYS程序对该Pall型摩擦阻尼器的滞回特性和力学特性进行了详细的分析。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,但这种新型安装方式的Pall型摩擦阻尼器与原Pall摩擦阻尼器的耗能能力有差距,提出了该安装方式的适用范围,在此基础上,提出了适合梯形框架的一种新型安装方式。

| Abstract: | In this paper a new type of application for the Pall-typed friction damper is put forward for the first time.The different slope of the isosceles trapezoid steel framework with the Pall-typed friction damper are analyzed by finite element analysis method in detail using the ANSYS program considering geometric nonlinearity,and this Pall-typed friction damper hysteresis characteristics and mechanical properties are analyzed.The results show that the installation of Pall-typed friction dampers can effectively increase the stiffness of the structure and enhance greatly the energy dissipation of the frame.But the new application of Pall-typed friction dampers have the different energy dissipation with the original Pall dampers,then put forward to the scope of application for this installation mode and another installation of Pall-typed friction damper for trapezoid frame. |
