ResumoThe classical first- and second order reliability methods as applied to complex systems are reviewed. They are justified and improved by new concepts of asymptotic analysis. Various asymptotically exact formulae are presented for the probability of simple failure domains and unions and intersections of such failure domains occuring in the reliability analysis of structural or other technical systems. Essentially, the computations are reduced to a problem of non-linear multi-constraint optimization and some simple algebraic manipulations. Two examples are presented which also show the effect of various simplifications.
