摘    要:对选用的两种摩擦力(库仑摩擦力、指数函数摩擦力)分别编程计算单质点的地震响应,运用newmark方法推导了库仑摩擦力下单质点地震响应的计算公式。对计算结果进行分析,得出质量比、摩擦系数对隔震效果的影响,并给出在文章假定的结构参数下,滑移面摩擦系数的取值范围。

关 键 词:摩擦系数 库仑摩擦力 指数函数摩擦力

Abstract:For the two selected friction (Coulomb friction and exponent function friction), the seismic response of single mass was computed by respective program . The seismic response calculation formula of single mass was deducted by the newmark method when regarding the friction as Coulomb friction. Analyze the calculated results,the mass ratio of single mass to sliding block and friction coefficient's effect on the seismic isolation is got.According to the supposed structural parameter in the paper, the range of sliding plane's friction coefficient is also obtained.
Keywords:friction coefficient  Coulomb friction  exponent function friction
