摘要

应用瞬态最优控制理论,在考虑上部结构刚度与阻尼的条件下,建立了基底摩擦力大小的计算方法,并对滑移隔震结构的半主动控制方法进行了研究.对实例计算结果的分析表明,半主动控制下的滑移隔震结构不但具有较好的隔震效果,而且能有效地减小基底的最大滑移量及残余位移.
Considering the super structure as elastomer, the semiactive control of sliding structure is studied by using instantaneous optimal control method. Numerical results show that the sliding structure using semi-active control not only has good vibration isolation effect, but also has less maximum slippage and less residual base displacement.
