| 摘 要： | 在悬索结构构件可靠度的基础上,以可靠度指标为失效模式识别的约界依据,通过对体系可靠度主要失效模式识别的3种计算方法的比较分析,生成较为精简的失效树,计算分析悬索结构的体系可靠度.分析表明:修正的β约界法在保证计算结果正确性的前提下,可以较大程度地精简失效树;悬索结构包含两个失效阶段的体系可靠度比包含一个失效阶段的体系可...

| Abstract: | Based on component failure of suspended structure, the reliability index is used as bounded basis for failure modes recognition, the system reliability of suspended structure is obtained by a more streamlined failure tree through comparative analysis of three methods of main failure modes recognition, and the following conclusions are received: 1)the amendment of β boundary law can be a greater degree of streamlining the failure tree to ensure accuracy of results. 2)the system reliability of the suspended structure consists of two invalidation phases is lower than the system reliability of the suspended structure consists of one invalidation phase. |
