摘　　要：本文根据双板型摩擦阻尼器的结构特点,分析了该摩擦阻尼器的工作特性,建立了使用该摩擦阻尼器的结构动力方程,并从实际结构各层摩擦阻尼器的初始滑移值出发,计算讨论了由结构层间位移的不同导致的摩擦阻尼器的耗能差异,由此得出摩擦阻尼器初始滑移值对结构响应的影响特性,从而进一步探讨了初始滑移值与实际结构各层摩擦阻尼器滞回特性和地震时程响应之间的关系,提出了如何改变摩擦阻尼器的初始滑移值以使各层摩擦阻尼器耗能最佳的解决方案。Based on the characteristic of double board friction damper, the peculiarity of it is analyzed and the dynamic equation is also established. Furthermore, according to the initial slippage of the friction damper, the energy dissipation discrepancy owing to the storey displacement is emphasized, which educes the response specialty of the friction damper due to the initial slippage. Eventually, the correlation among initial slippage, hysteretic properties and time history response is exhaustively discussed and the method which attains the prime energy dissipation is ultimately gained.
