摘　　要：采用在结构水平双向设置 TLCD半主动控制装置的方法 ,对偏心结构在多维地震作用下的振动控制问题进行了研究。首先论述了基于 Takagi-Sugeno模型的模糊神经网络的基本理论 ,然后介绍结构 -TLCD扭转耦联控制系统微分方程及其状态空间求解方法 ,最后在建立起半主动控制策略的基础上 ,利用基于 Takagi-Sugeno模型的模糊神经网络 ,根据控制准则调整 TLCD的开孔率 ,实现对结构的半主动控制。数值结果表明 。A control approach to the irregular building excited by multi-dimensional earthquake ground motions is presented by using semi-active tuned liquid column damper (TLCD). The theory of fuzzy neural network (FNN) based on the Takagi-Sugeno model is firstly discussed. And then, the numerical model of a multi-story irregular structure-TLCD system is given and its equation of motion is derived. The semi-active control strategy is established and implemented by FNN. The numerical examples show that it is an effective method proposed for controlling the translational response and rotational response of the irregular buildings.
