This International Standard constitutes a risk- and reliability-informed foundation for decision makingconcerning design and assessment of structures both for the purpose of code making and in the contextof specific projects.The principles presented in this International Standard cover the majority of buildings, infrastructure,and civil engineering works, whatever the nature of their application and use or combination of thematerials used1). The application of this International Standard will require specific adaptation anddetailing in special cases where there are potentially extreme consequences of failure2).This International Standard is intended to serve as a basis for those committees responsible for the taskof preparing international standards, national standards, or codes of practice in accordance with givenobjectives and context in a particular country.The present International Standard describes how the principles of risk and reliability can be utilized tosupport decisions related to the design and assessment of structures and systems involving structuresover their service life. Three different but related levels of approach are facilitated, namely, a riskinformed,a reliability-based, and a semi-probabilistic approach.The general principles are applicable to the design of complete structures (buildings, bridges, industrialstructures, etc.), the structural elements and joints making up the structures and the foundations. Theprinciples of this International Standard are also applicable to the successive stages in construction,the handling of structural elements, their erection, and all work on-site, as well as the use of structuresduring their design working life, including maintenance and rehabilitation, and decommissioning.Risk and reliability are concepts accounting for and describing actions, structural response, durability,life-cycle performance, consequences, design rules, workmanship, quality control procedures, andnational requirements, all of which are mutually dependent.The application of this International Standard necessitates knowledge beyond what is contained inthe Clauses and the Annexes. It is the responsibility of the user to ensure that this knowledge isavailable and applied.
