本文采用混合控制方法对滞回非线性建筑结构的抗震控制进行研究，给出优化控制 算法，并对其充要条件进行论证。其中，被动控制采用基底橡胶支撑，主动控制采用主动质 量阻尼器（ＡＴＭＤ），结构非线性恢复力采用Ｗｅｎ模型形式。算例计算结果表明，建筑结构的 混合控制方法的效果明显优于被动控制方法。另外，文中所用控制策略同样也适合于其它组 成形式的混合控制，如主动作动器和摩擦型基底隔离组成的混合控制等。
In this paper, the hybrid control method is used to study the aseismic control of hysteretic nonlinear structures. The optimal control algorithm is given and the necessary and sufficient conditions are demonstrated. Among them, the passive control adopts the base rubber support, the active control adopts the active mass damper (ATMD), and the nonlinear restoring force of the structure adopts the Wen model form. The calculation results of the example show that the hybrid control method of building structure is obviously better than the passive control method. In addition, the control strategy used in this paper is also suitable for hybrid control of other components, such as hybrid control consisting of active actuator and friction substrate isolation.
