The structural reliability recommended in Eurocodes and other international documents vary within a broad range, while the regard to the failure consequences and style working life is mentioned only very vaguely. In some cases the target reliability indexes are indicated for one or two reference periods like 1 to 5-0 years, however no explicit link to the planning working life is typically provided. This text attempts to clarify the connection between the target reliability levels, failure consequences, the planning working life and therefore the discount rate. The theoretical study supported probabilistic optimization is supplemented by recommendations useful for code makers and required by practicing engineers. It appears that the optimum reliability indices depend totally on the ratio of the value of structural failure to the value per unit of structural parameter, and fewer significantly on the planning working life and on the discount rate.
