ISO 22111:2019 PDF Download

ISO 22111:2019 sets out the general principles and requirements for structural design and procedures. It follows a semi-probabilistic approach that aligns with the principles for structural reliability outlined in ISO 2394. The standard focuses on structures for which there is adequate knowledge and experience in design and construction practices to ensure target levels of reliability, considering the nature and consequences of structural failure. Situations falling outside these limitations are covered by ISO 2394.

The standard includes semi-probabilistic limit states approaches, which have been validated to achieve sufficient and consistent levels of structural reliability. These methods are used to assess the performance of structures and determine design measures. ISO 22111 relies on standardized procedures for the characterization of the load-bearing capacity of structures within its scope. It also emphasizes the need for sufficient information on uncertainties associated with design variables and models to derive semi-probabilistic design measures for verifying structural reliability in accordance with this standard and other related design standards.
