带有耗能器的基底滑动结构隔震效果研究

对带有基底滑动隔震系统及耗能器系统的结构进行了研究，建立了三种情况下的数学模型，推导了有关公式，并编制了相应的计算程序，研究了一座四层建筑物在ＥｌＣｅｎｔｒｏ地震波作用下的位移响应，加速度响应、层间剪力响应等，考虑了不同摩擦系数、不同加速度峰值及附加耗能器不同参数时对结构隔震效果的影响。并与相应的线生结构进行了比较，通过计算分析，得出结构隔震和耗能的有关结论。

Study on the Effect of Vibration Isolation of Base Sliding Structures with the Absorber

The system of base sliding structures with an absorber is presented. Models for three cases,i.e.,normal structures, base sliding structures and base sliding sturctures with an absorber have been established, some formulas are derived, and a corresponding program is compiled. Displacement responses, acceleration responses and responses of shear between two storeys of a four storey building excited by El centro waves are studied, the influence on the vibration isolation effect of different friction factors, acceleration peak and parameters of the absorber are considered, and the results are comparied with the result of the linear elastic structures. After synthetical analysis, some conclusions about vibration isolation of structures and the absorber are drawn.
