本文件提供了遵循符合ISO 2394规定的结构可靠性一般原则的半概率方法的结构设计和程序要求。因此，要求和程序的范围仅限于结构的设计，对于这些结构，设计和施工实践中通常有足够的知识和经验，以确保目标可靠性水平考虑到结构故障的性质和后果。ISO 2394涵盖了这些限制之外的情况。 本文件中包含的方法是半概率极限状态方法，经证明可实现足够且一致的结构可靠性水平。 本文件依赖于在其范围内表征结构承载性能的标准化程序。 设计变量和模型的不确定性需要足够的信息，以便能够得出半概率设计措施，以验证本标准和相关设计标准范围内的结构可靠性。

This document provides the requirements for structural design and procedures following a semi-probabilistic approach that conform to the general principles for structural reliability as stipulated by ISO 2394. The scope of requirements and procedures are accordingly limited to the design of structures for which sufficient knowledge and experience are commonly available on design and construction practice to ensure that target levels of reliability account for the nature and consequences of structural failure. Situations outside these limitations are covered by ISO 2394. The methods that are included in this document are the semi-probabilistic limit states approaches that are proven to achieve sufficient and consistent levels of structural reliability. This document relies on standardized procedures for the characterization of the load bearing performance of the structures within its scope. Sufficient information is needed on uncertainties of design variables and models to be able to derive semi-probabilistic design measures for verification of structural reliability within the scope of this and the related design standards.
