The theory of structural reliability becomes a powerful scientific tool used for the development of new standards, and alternatively for the direct verification of new and existing structures. It is demonstrated that recently revised national and international standards for structural design including ISO standards and Eurocodes are already based on probabilistic concepts, mathematical statistics and on the theory of structural reliability. The background documents of Joint Committee on Structural Safety (JCSS) constitute a common basis for defining design rules relevant to the construction, use and verification of wide majority of buildings and civil engineering works. The key role in the design of new and particularly in assessment of existing structures is played by the target reliability level and the concept of reliability differentiation. Further, the scientific bases formed by the First Order Reliability Methods (FORM) provide effective methods for probabilistic code calibration based on the concept of limit states in conjunction with the partial factors methods. Foreseen future development and revisions of the present structural codes presuppose systematic use of the probabilistic theory of structural reliability.
