Abstract

Specification of the target reliability levels is one of the key issues of the assessment of existing systems. ISO 2394:2015 indicate procedures for specification of the target reliability levels by optimisation of the total cost related to an assumed remaining working life of a structural system. These approaches are critically compared with human safety criteria and with recommendations of present standards. It appears that the requirement on the same target reliability levels for existing civil engineering systems as for newly designed is uneconomical. Decisions in the assessment can result in the acceptance of the actual state or in upgrade of the existing structure, two reliability levels are thus needed - the minimum level below which the structure is unreliable and should be upgraded, and the target level indicating an optimum upgrade strategy. When reliability of a system or its key component is verified (as compared to design of a common component), the target reliability index should be increased by about 0.5.

现有土木工程系统的目标可靠性

目标可靠性水平的确定是现有系统评估的关键问题之一。ISO 2394:2015指明了通过优化与假定的结构系统剩余工作寿命相关的总成本来规范目标可靠性水平的程序。这些方法与人类安全标准和现行标准的建议进行了严格的比较。对现有的土木工程系统和新设计的系统要求相同的目标可靠性水平似乎是不经济的。评估中的决策可以导致接受实际状态或对现有结构进行升级，因此需要两个可靠性水平-低于该结构不可靠并应升级的最低水平，以及表示最佳升级策略的目标水平。当对系统或其关键部件进行可靠性验证时(与设计通用部件相比)，目标可靠性指标应提高0.5左右。
