中文摘要
      用作动器将相距很近的两结构连为一体,并对其中一个结构施加隔震,形成一种新的结构体系—组合隔震结构体系.推导了其振动及控制方程,假定地震动输入为白噪声,运用随机最优控制原理,分析研究了组合结构振动控制性能及隔震度、阻尼及场地等参数的影响.研究结果表明:经过优化控制参数,组合隔震结构振动控制体系能对结构地震响应进行有效控制,并且控制成本降低.
英文摘要
      Two building structures neighboring each other are linked with actuators,and one of them is isolated,then a new pattern of structure,a combination of isolated structures,is formed.The vibration and control equations of this new system are derived in this paper.Regarding the input of earthquake as a white noise and using the principle of random optimal control,features of vibration control and effect of parameters such as isolation degree,damping and ground site are analyzed.The conclusions indicate that vibration-control system of combined structures can bring the seismic responses of structures under effective control by optimizing the control parameters of structure,and the cost of control can be reduced.
