The International Organization for Standardization (ISO) published a standard targeted at helping engineers, builders and regulators to design structures that are safe and resistant to failure due to environmental and mechanical stresses, and to material degradation.
ISO 13823:2008 - General principles on the design of structures for durability specifies general principles and recommends procedures for the verification of the durability of structures subject to known or foreseeable environmental actions, including mechanical actions, causing material degradation leading to failure of performance.
This international standard seeks to:
- Improve the evaluation and design of structures for durability by the incorporation of building science principles into structural engineering practice.
- Provide a framework for the development of mathematical models to predict the service life of components of the structure.
"The general principles in the verification and design of structures and components for durability in this international standard should be used whenever a minimum service life is required, for new structures as well as for the assessment of existing structures," said A.M. Brandt, chair of ISO/Technical Committee (TC) 98 - Bases for design of structures.
ISO 13823:2008 covers the following:
- Basic concept for verifying durability.
- Durability requirements.
- Design life of a structure and its components.
- Predicted service life.
- Strategies for durability design.
According to ISO, this international standard does not directly address sustainability for structures. Most considerations of sustainability, such as the choice of material as it affects waste and energy consumption, are outside its scope.
