摘要
本文基于β-分解，引入人工智能概念，对空间刚架结构进行系统可靠性分析．在进行主要失效途径识别时，来用人工智能中启发式搜索的思路，建立临界失效概率的概念，改进了β-分解法中的经验性，从而减少了计算时间.使用本文提出的方法，对船舶结构等算例作了计算，表明本文所提出的方法及方法的实施都是有效而且合理的．
By introducing the concept of artificial intelligence technique (AI), the β-unzippingmethod is updated and used in structure system reliability analysis for space frame. In thispaper, the idea of heuristic search in the solving problem with AI is employed. The critical failure probability is introduced as the approach value to identify the dorninant failurepath. Typical ship structures are analysed to verify the efflciency of the proposed method.
