摘要
探讨了采用铅芯橡胶的基础隔震、上部实施ＡＭＤ控制的混合控制系统的随机反应，利用Ｙ．Ｋ．Ｗｅｎ提出的滞回模型描述橡胶的非线性变形，用算例阐明了隔震器参数和ＡＭＤ参数对结构的随机反应的影响，时程分析表明混合控制系统优于隔震系统或主动控制系统．
Stochastic analysis of hybrid control system which is composed of steel plate reinforced rubber pads and an Active Mass Damper (AMD) is explored. Numerical model proposed by Y. K. Wen is used to approximate the nonlinear deformation of rubber isolators. Numerical examples are worked out to demonstrate the influence of parameters of isolator and AMD on stochastic response of structures. Results of time history analyses have shown the advantage of hybrid control system over isolation system or active control system.
