摘要
Ved(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。推导了粘弹性阻尼器和人字型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 ,设置粘弹性阻尼器人字型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 of suppressing vibration and dissipating energy. In story frame structures are investigated. The stiffness matrix of element composed of viscoelastic damper and Λ shape steel brace is established. The method of nonlinear responses of the multi- story frame structure this paper, the calculation methods of viscoelastic damper controlling nonlinear earthquake responses of multi-installed viscoelastic damper under intensity of seldom occurred earthquake is developed.
