EN ISO 13823 General Principles for the Design of Structures for Endurance

Developed by the International Organization for Standardization (ISO), the EN ISO 13823 standard specifies general principles and recommends procedures for verifying the durability of structures exposed to known or foreseeable environmental influences, including mechanical actions that cause material degradation leading to performance failure.

EN ISO 13823 General Principles for the Design of Structures for Endurance

It is necessary to ensure reliability of performance throughout the design service life of the structure. Fatigue failure due to cyclic stress is not covered by this International Standard. ISO 2394 can be consulted for failures caused by fatigue.

The initial aim of developing this International Standard is to improve the design and evaluation of structures for durability by incorporating the principles of building science into the practice of structural engineering. These principles are now taught in engineering courses in many countries. To this end, these principles are already structured.
It is achieved by incorporating the boundary-state method used in engineering practice and defined in ISO 2394, and using a common, user-friendly terminology for physical phenomena.

Recently there have been advances in the mathematical modeling of mechanisms that cause material deterioration and failure. There is a need to harmonize the practical use of these models using the limit state method and a common terminology.

The second purpose of developing this International Standard is to provide a framework for the development of mathematical models to predict the service life of the components of the structure. Such models are currently being developed, for example, for concrete slabs subjected to chloride diffusion from de-icing salts. These models are material dependent and are therefore being developed by other ISO/TCs. The purpose of this International Standard is all analytical, the same as currently used for the verification and design of structures for the actions of gravity, wind, snow and earthquakes.
is to ensure that the models are included in the limit state method.

While this International Standard does not address design procedures for durability, it provides a solid foundation by defining a process that starts from the periphery of the structure, followed by mechanisms that translate into environmental actions on component materials that cause action effects such as damage. This cause-effect process needs to be taken into account when developing methods for estimating service life.

This International Standard is intended to be used in parallel with ISO 15686 (all parts) in service life planning for buildings and construction assets. The service life estimate for structures based on experience and testing is contained in ISO 15686 (all parts). Service life prediction of structures based on durability modeling in addition to experience and testing using conceptual and mathematical models is described in this International Standard.

This International Standard is intended to use general principles in the verification and design of structures and components for durability, for evaluation of existing structures as well as for new structures when minimum service life is required. The considered components include non-structural components that may affect the durability of the structure.

General principles include planning of maintenance, repair and replacement measures, fault investigations, etc., as well as the design phase. It also applies to However, additional considerations may apply to existing structures.

For existing structures, the procedures and criteria in this International Standard may be modified to take into account the results of inspection and testing related to changes in workmanship, maintenance conditions and durability of materials. In addition, lower target confidence levels can be used for existing structures if they can be justified.
