本文给出了一种结构系统余度的度量定义。基于结构系统机构化失效概念和相当可靠性指数,本文提出了对受损结构安全性评估的半概率方法。所示算例表明了本方法的有效性。
This paper gives a definition of the metric of structural system redundancy. Based on the concept of institutionalized system failure and the relative reliability index, a semi-probabilistic method for evaluating the safety of damaged structures is proposed. The example shown shows the effectiveness of this method.
