| 摘 要： | 介绍了粘弹性阻尼器的设计过程,推导了基于振型分解反应谱法粘弹性阻尼器的设计方法;检验了此方法的精确度及使用范围;分析了随粘弹性阻尼器附加刚度的增加,附加阻尼比的变化规律;给出了粘弹性阻尼器储存刚度与层刚度的合理比值范围.根据粘弹性阻尼器的力学特性,对一设置粘弹性阻尼器的钢框架进行ANSYS模拟,并对纯框架结构和安装粘弹性阻尼器的框架结构在罕遇地震下的响应进行对比分析.结果表明：设置粘弹性阻尼器后,结构的地震响应明显降低.

| Abstract: | A design process and the design method for viscoelastic dampers(VEDS) were in troduced on the basis of response spectrum method.Its accuracy and application range were tested.The law of change of additional damping ratio was studied with the increase of additional stiffness,and the reasonable range of the ratio between storage stiffness of viscoelastic damper and storey stiffness was given.According to mechanical property of VEDS,a steel frame with VEDS was simulated.The responses of the structure without V... |
