Study on Structural Reliability Analysis Method Based on Chance Theory

Many factors influence structural reliability in practice engineering. Some can be measured to obtain lots of data, but others are difficult acquire statistical data. In view this situation, a new analysis method is proposed using chance theory, which composed probability theory and uncertainty reflect random cognitive simultaneously. The performance function mechanical element defined, when it uncertain variable, the distribution established. Then calculated failure measures for put forward. Furthermore, considering series system parallel system, proposed, measure determined by theoretical proof. results provide approach analyzing under circumstance lack
