Abstract

A method in estimating the conservative reliability by calculating algebraic sum of damage is proposed. The conditions that this method could be used to get the conservative estimation is calculated for several distributions. Combined with application examples, the feasibility and rationality of this method are validated by comparing the results of this method and Monte-Carlo simulation.
