摘　　要：研究平动PTMD(translation passive tuned mass dampers)和转动PTMD(rotational passive tunedmass dampers)的参数变化对剪切型结构地震反应的影响。并采用MATLAB中的SIMULINK工具箱进行动态仿真,得出受控结构的动态反应,将两种控制方法应用到某十层建筑上,计算分析的数值结果表明两者用于控制顶层相对位移和绝对加速度都是比较有效的。The effects of parameters of translation PTMD （passive tuned mass dampers） and rotational PTMD on earthquake responses of shear structures are discussed in this paper. Dynamic simulation is carried on through the SIMULINK toolbox in MATLAB to get pie is applied to a 10 -story building. Numerical the dynamic responses of the controlled structure. An examresults show that both translation PTMD and rotational PT- MD can control top floor relative displacement and top floor absolute acceleration efficiently.
