本文应用随机最优控制理论提出了用基底滞后隔震层把大震烈度下多层剪切型结构的地震反应控制在弹性范围内的设计计算方法.文中在建立了基底设置隔震层建筑结构计算模型的基础上,确定了它随机地震反应最优控制的评价函数和可靠性约束;并在应用最优控制论导得基底等价线性耗能器的最优反馈增益的前提下,最终得到了把大震烈度下结构地震反应控制在弹性范围内的基底滞后隔震层最优设计参数的计算公式.
In this paper, a stochastic optimal control theory is proposed to design a method for controlling the seismic response of a multi-layered shear structure under large earthquake intensity in the elastic range using a base-lag seismic isolation layer. On the basis of the calculation model, the evaluation function and reliability constraints of its optimal control for random seismic responses are determined; and under the premise of applying the optimal control theory to derive the optimal feedback gain of the base-equivalent linear energy consumer, it is finally obtained. The calculation formula of the optimal design parameters for the base-lag isolation layer with the structural seismic response under large earthquake intensity controlled in the elastic range.
