Abstract

Structural health monitoring (SHM) projects are mostly based on semi-empirical decisions, emphasising the importance of the structure and lacking a rational comparison of the benefits and costs. The present work offers guidance to overcome this, based on an objective framework using the quantification of the value of SHM in an engineering context. Firstly, procedures for practising engineers are outlined on the basis of the COST guidelines. Secondly, a case study, focused on the reliability of a historic masonry structure, demonstrates the optimisation of surveys based on non-destructive tests calibrated by destructive tests. Both the outlined procedures and case study are carefully prepared and in tune, so the reader can easily understand the feasibility of the framework. Decisions on the utilisation of SHM in practical applications can be effectively achieved based on the highest expected utility gained by SHM. For this, two scenarios are needed: (i) a scenario with at least one SHM strategy and (ii) a scenario without any SHM.

摘要

结构健康监测（SHM）项目大多基于半经验决策，强调结构的重要性，缺乏对收益和成本的合理比较。目前的工作基于在工程环境中使用 SHM 价值量化的客观框架，为克服这一问题提供了指导。首先，根据 COST 指南概述了执业工程师的程序。其次，一个以历史砌体结构的可靠性为重点的案例研究，展示了基于由破坏性测试校准的非破坏性测试的勘测优化。概述的程序和案例研究都经过精心准备和协调，因此读者可以轻松理解框架的可行性。基于 SHM 获得的最高期望效用，可以有效地实现 SHM 在实际应用中的利用决策。为此，需要两个场景：（i）具有至少一个 SHM 策略的场景和（ii）没有任何 SHM 的场景。
