摘要

在分析了当前结构动力可靠度领域里存在的一些基本问题之后,研究了结构动力反应过程的相关性及动力失效的相关性.从条件概率的基本概念入手实现了动力相关性问题的转化,提出了结构动力反应过程"完全相关形式"的唯一性(一致性),并给出了该性质的证明.应用此性质解决了目前难于解决的体系动力可靠度中的关键性问题———动力相关性问题,建立了求解结构体系动力可靠度更精确的方法———动力PNET方法(称为DPNET法).
Based on analyzing some existing problems in the field of structural reliability under dynamic action, the correlativity in the process of structure dynamic response and the correlativity of structure dynamic failure are studied. The problem about correlativity of dynamic failure of structure is transformed based on analyzing the basic concept of condition probability, and the uniqueness of "complete correlation form" is brought forward and proved. For these, the problem about systematic reliability under dynamic action that can not be easily dealt with at present is solved, at the same time, a kind of more accurate method, dynamic PNET method(called DPNET method), for calculating the systematic structural reliability under dynamic action is founded.
