ISO 13822:2010提供了基于结构可靠性和故障后果原则的现有结构（建筑物、桥梁、工业结构等）评估的一般要求和程序。它基于ISO 2394。 ISO 13822:2010适用于根据公认的工程原理和/或设计规则最初设计、分析和规定的任何类型的现有结构，以及基于良好工艺、历史经验和公认的专业实践建造的结构的评估。 评估可在以下情况下启动:预期用途变更或设计使用寿命延长；当局、保险公司、业主等要求的可靠性检查（如地震、交通活动增加）。 ; 时间相关作用（如腐蚀、疲劳）导致的结构劣化；意外作用造成的结构损坏（见ISO 2394）。 ISO 13822:2010也适用于遗产结构，前提是考虑了附件I中所示的其他考虑因素。 ISO 13822:2010适用于任何材料的现有结构，但根据材料类型，如混凝土、钢、木材、砌体等，可能需要进行特定的调整。 ISO 13822:2010提供了有关行动和环境影响的原则。对于火灾和地震等意外行为，需要进一步详细考虑。 ISO 13822:2010旨在作为根据当前工程实践和经济条件制定国家标准或实践规范的基础。

ISO 13822:2010 provides general requirements and procedures for the assessment of existing structures (buildings, bridges, industrial structures, etc.) based on the principles of structural reliability and consequences of failure. It is based on ISO 2394. ISO 13822:2010 is applicable to the assessment of any type of existing structure that was originally designed, analysed and specified based on accepted engineering principles and/or design rules, as well as structures constructed on the basis of good workmanship, historic experience and accepted professional practice. The assessment can be initiated under the following circumstances: an anticipated change in use or extension of design working life; a reliability check (e.g. for earthquakes, increased traffic actions) as required by authorities, insurance companies, owners, etc.; structural deterioration due to time-dependent actions (e.g. corrosion, fatigue); structural damage by accidental actions (see ISO 2394). ISO 13822:2010 is also applicable to heritage structures provided additional considerations shown in Annex I are taken into account. ISO 13822:2010 is applicable to existing structures of any material, although specific adaptation can be required depending on the type of material, such as concrete, steel, timber, masonry, etc. ISO 13822:2010 provides principles regarding actions and environmental influences. Further detailed considerations are necessary for accidental actions such as fire and earthquake. ISO 13822:2010 is intended to serve as a basis for preparing national standards or codes of practice in accordance with current engineering practice and the economic conditions.
