摘　　要：本文通过两类四种百余个耗能器(其中摩擦类型的两种,普遍摩擦型和Pall摩擦型;软钢屈服类型的两种:X钢板和三角钢板屈服型)的静力反复加载和低周疲劳试验,进一步了解这些耗能器的滞回特性和疲劳性能。其次,通过分别安装上述四种耗能器的单层剪切型钢框架模型在输入地震动分别为ElCentro、Taft和天津记录等五十余种工况下的振动台试验,较全面地揭示了这些耗能器的减振效果。最后,在试验的基础上较好地建立了上述四种耗能器的恢复力计算模型和参数确定方法,从而为进一步分析这些耗能器对多层或高层框架结构的减振效果提供了基础。In this paper,one hundred or more energy dissipators,which are divided into friction and mild steel yielding types including normal friction and Pall friction energy dissipators and X shape and triangular steel plate yielding energy dissipators are tested by the static recycle loading and fatigue experiment and their hysteretic and low cycle fatigue properties are further studied and made a comparison. Then,the effects of above four kinds of energy dissipators on reducing vibration of one story shear-type steel frame respectively under El Centre,Taft and Tianjin earthquakes are investigated and made a comparison by shaking table tests. Based on the experimental results the restoring force models of above four kinds of energy dissipators are established and the parameters in the models are determined.
