Summary

Structural reliability is treated as a stochastic problem, and first as a single stochastic process model. The problem can be interpreted as one in which the transition probability changes with elapsed time. Weibull, logarithmic normal, and dual exponential distribution functions can be derived as special cases. On the other hand it is shown that in some cases a model of successive stochastic processes may be more suitable. Also, for practical purposes in structural reliability, a method is proposed to estimate the failure life in the range of very small probability of failure. Furthermore, comparison is made with the reliability engineering approach for machines or devices, and human beings.
