摘要
研究了时变结构的自振特性和动力反应 ,建立了随机时变结构的自振和动力反应方程。考虑荷载为 Markov随机过程模型 ,提出了基于该模型的随机时变结构动力可靠度分析方法。
Natural vibration and dynamic response on time dependent structure are analyzed, the equations of natural vibration and dynamic response are set up. Considering load as Marcov model the dynamic reliability analysis method is given in this paper.
