ISO 13824:2009规定了涉及结构的系统风险评估的一般原则。重点是与结构设计、评估、维护和退役相关的战略和运营决策。这还包括制定和校准相关规范和标准。涉及结构的系统可能使社会各阶层的利益相关者面临重大风险。ISO 13824:2009旨在以高效、低成本的方式促进和加强有关监控、降低和管理风险的决策- 有效和透明的方式。在更广泛的风险管理背景下，风险评估为决策者提供了确定是否以及以何种方式处理风险的程序。 ISO 13824:2009提供了一个总体框架和程序，用于识别危险以及评估、评估和处理涉及结构的结构和系统的风险。ISO 13824:2009还为代码编写者和设计人员提供了依据，以根据风险考虑的结果设定合理的目标可靠性水平，如ISO 2394中所述。 对于现有结构，应根据ISO 13824:2009中规定的原则，评估与原始设计中未考虑的事件或使用变更相关的风险。ISO 13824:2009还可用于特殊结构的风险评估，其设计通常超出现有规范的范围。

ISO 13824:2009 specifies general principles on risk assessment of systems involving structures. The focus is on strategic and operational decision-making related to design, assessment, maintenance and decommissioning of structures. This also includes formulation and calibration of related codes and standards. Systems involving structures can expose stakeholders at various levels in society to significant risks. The aim of ISO 13824:2009 is to facilitate and enhance decision-making with regard to monitoring, reducing and managing risks in an efficient, cost-effective and transparent manner. Within the broader context of risk management, risk assessment provides decision makers with procedures to determine whether or not and in what manner it is appropriate to treat risks. ISO 13824:2009 provides a general framework as well as a procedure for identifying hazards and estimating, evaluating and treating risks of structures and systems involving structures. ISO 13824:2009 also provides a basis for code writers as well as designers to set reasonable target-reliability levels, such as stated in ISO 2394, based on the result of risk considerations. For existing structures, assessment of the risks associated with the events that were not considered in the original design or with changes in use shall be implemented according to the principles stated in ISO 13824:2009. ISO 13824:2009 can also be used for risk assessment of exceptional structures, the design of which is usually beyond the scope of existing codes.
