摘 要: 根据粘弹性阻尼器的特点,给出了装设粘弹性阻尼器消能减震结构等价阻尼比的简化计算公式;结合我国抗震设计规范,提出了考虑高阶振型影响的粘弹性阻尼器消能减震结构体系的能力谱分析法,并对一8层钢筋混凝土消能减震框架结构在设防中震作用下进行了计算分析,结果表明采用该方法分析粘弹性阻尼器消能减震结构体系是可行的、有效的。 According to the characteristic of viscoelastic dampers, simplified formulae of equivalent viscous damping ratio for structures with viscoelastic dampers are presented. In terms of seismic design code, the capacity spectrum method taking into account high modes is put forward for analyzing reinforced concrete structures with viscoelastic dampers. Finally, a eight-story reinforced concrete frame with viscoelastic dampers is analyzed. The results indicate that this method is viable and effective.
