我国黏弹性阻尼器抗震疲劳性能检验标准研究
National Standard Research for Seismic Fatigue Performance Test of Viscoelastic Dampers
摘要
Abstract
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.关键词
