Codified criteria for reliability differentiation and risk informed decisions inherent in standards and especially in the Eurocodes are critically reviewed. WebWhat is Reliability class Eurocode? The basic elements of reliability as stated in section 2.2 of the Eurocode are safety, serviceability and durability.
