| Abstract: | An investment-benefit model was developed that helps to minimize the costs of failure prevention in engineering.Based on the theory of the weakest failure modes of structural systems,the structural system reliability design was approached using the optimization and control method.It showed that structural system reliability can be optimized and controlled by optimizing the weakest failure modes.The main factors influencing failure were defined by interrelationships in the rules of reliability,the index vect... |
