Target Reliability for Engineering Structures
Original language description
The target reliability levels recommended in national and international documents vary within a broad range, while the reference to the cost of construction and failure consequences is mentioned only very vaguely. In some documents the target reliability index β is indicated for one or two reference periods (1 year and 50 years) without providing an appropriate link to the design working life. This contribution attempts to clarify the relationship between the target reliability levels, structural costs, failure consequences, reference period, the design working life and the discount rate. The theoretical study based on probabilistic optimization is supplemented by recommendations useful for code developers and practicing engineers. It appears that the optimal reliability level depends primarily on the construction costs, failure costs and relative cost for improving structural safety, and less significantly on the discount rate and the time to failure. In design based on the partial factor method, it is recommended that the characteristic values of the basic variables be defined independently of the design working life; to specify the design values on the bases of optimal reliability index; and to derive the partial factors from the specified design values and defined characteristic values.
