摘要
粘弹性阻尼器是抗震被动控制中一种十分有效的耗能减震装置。本文推导了粘弹性阻尼器和斜支撑的组合层间单元刚度矩阵，并建立了在罕遇地震作用下，设置粘弹性阻尼器斜支撑的钢筋混凝土框架结构非线性地震反应时程分析的方法。
Viscoelastic damper is a kind of efficient device for suppressing vibration anddissipating energy. In this paper, the calculation methods of viscoelastic damper controllingnonlinear earthquake responses of multistory frame structures are investigated. The stiffness matrix of the elements composed of viscoelastic damper and steel brace is established. The methodfor calculating nonlinear responses of the multi-story frame structure including viscoelasticdamper under intensity of seldom occurred earthquake is developed.
