Notes:
An approximate analytical method is presented to analyze reliability for the structurewith fuzzy-random uncertainty in basic variables. On the basis of equivalent transformation fromfuzzy possibility distribution (FPD) to random probability distribution (RPD), this contributionexpands first order and second moment method (FOSM) for random reliability to that forfuzzy-random reliability. The expanded FOSM is illustrated by the way of the fuzzy-random lowfatigue life reliability analysis about an aeronautical engine disk affected by fuzzy-randomuncertainty. Comparison between the FOSM and the numerical simulation for the fuzzy-randomreliability demonstrates the precision of the presented computational model
