Annotation: Considered are advantages and disadvantages of the standard approach, when the level of structural reliability is estimated qualitatively only. The increasing role of probability models in the pipeline design is underlined. Relationship between safety factor and standard reliability is determined.

 

Key words: standard design method, probability-and-standard- method, bearing capacity of the structure, safety factor, structural reliability.
