摘　　要：定义了能量变化率指标,以简谐激励作用下的滑移隔震结构为例,探讨了摩擦系数对滑移隔震结构能量变化率指标的影响,通过对这些能量指标的研究,分析了系统的相对输入能量和绝对输入能量的差异性随摩擦系数的变化规律,为后续研究提供理论依据。Indexes of rate of the energy change are defined in this paper, a discussion is made on the influence of the friction coefficient on these indexes of sliding base isolated structure subject to harmonic excitations. Based on the study of these energy indexes, the change rule of the differences between the relative energy input and the absolute energy input of the system with friction coefficient are analyzed, thus, the theoretical basis for further study has been set up.
