摘　　要：我国黏弹性阻尼器在生产和应用过程中均需要进行抗震疲劳性能检验。我国现行的消能阻尼器标准中均对黏弹性阻尼器的抗震疲劳性能检验方法进行了规定。对现行标准中相关的试验加载制度和性能评价方法进行了汇总和比较,并基于此,对四种黏弹性阻尼器进行了抗震疲劳性能试验和性能参数分析。结果表明,基于不同标准得到的阻尼器力学性能参数的变化率不同,是否满足15%限值的结论也不相同。The seismic fatigue performances of viscoelastic dampers(VEDs)are needed to be tested in production and application.The test methods of seismic fatigue performances for VEDs are specified in the current national standards for energy dissipation dampers.In this paper,the test loading protocols and the performance evaluation methods in present standards are summarized and compared,and based on this,four kinds of VEDs were tested and their mechanical parameters were analyzed.The results show that,based on different standards,variation rates for each mechanical parameter are different,and the conclusions whether the 15%limit is satisfied are also inconsistent.
