摘要
本文通过引入模糊随机变量的确定率和广义可靠性指标,将工程结构的模糊随机可靠度与模糊随机信息的数字特征联系起来,提出了计算模糊随机可靠度的简化实用方法——验算点法,其计算工作量与普通可靠度计算的验算点大致相当。
In this paper, a new concept of definite proportion of random fuzzy variables is introduced and the generalized reliability index is defined. Thus the random fuzzy reliability of engineering structures can be related with numerical characteristics of various uncertain information. Then a simple and useful method for random fuzz-y reliability of structures, the design point method, is presented. The amount of calculation work of this method is nearly the same as that required for the conventional reliability calculation.
