摘要
对考虑模糊性时的结构强度可靠性理论进行了初步研究。分析了结构安全这一事件的模糊性的来源和模糊性对结构强度可靠性的影响,建立了结构安全这一模糊事件的隶属函数的一般表达式,提出了结构强度模糊可靠度的计算方法,并以简支梁为例对其模糊可靠度进行了分析计算。
This papcr presents an initial invcstigation on reliability theory of structural strength in-volved with fuzziness.The source of fuzziness in stiuctural safety and the influence resulted frcm fuzzlness on sthectural strength rallability are analysed.the membership function expression of structural safety is establisbed.the calculation methods of fuzzy reliability of structural strength are also presente,and as an example,the fuzzy reliability of frecly supported beam is calculated.
