This chapter summarizes the state of the art and current developments of guidelines for structural health monitoring (SHM) and performance control. Technical guidelines and standards for condition monitoring and technical diagnostics of rotary machines and for non-destructive testing are not reviewed in this chapter. They were mentioned in the related chapters of this book (see Chaps. 4 and 19).

General

Today, in the field of structural health monitoring, only a few technical guidelines exist. They were developed and published by national or international scientific or technical organizations. Up to now, no standard is published or under development in this field by an international standardization organization. Existing guidelines can be divided into two main categories: guidelines for SHM of civil engineering structures like bridges and of other complex technical structures like offshore construction. Some of the most important guidelines in each field are introduced in the following sections.

Civil Engineering Structures

One leading guideline in the field of SHM of civil engineering structures has been published by the ISIS Canada—The Canadian Network of Centres of Excellence on Intelligent Sensing for Innovative Structures [1]. Within this network of universities and research institutes, for many years, research has been conducted to develop advanced technologies to facilitate remote monitoring. Additionally, the durability and reliability of SHM systems was demonstrated for 5 years in demonstration projects located across Canada. The ISIS guideline focuses on SHM as a diagnostic tool and the various components that comprise a SHM system. The basic purpose is to expose the benefits of SHM to structural engineers who are not fully cognizant of this field of engineering. The guideline is also useful to engineers who are already involved in some aspect of SHM and would like to expand their knowledge about other aspects. It is divided into eight chapters and three annexes. After introducing basic concepts of SHM, the composition of structural health monitoring system is described. Two chapters are dedicated to static and dynamic field testing. How to perform periodic monitoring of a civil engineering structures is illustrated in a separate chapter. Ten examples of bridge and wharf monitoring are described in a detailed manner. At first, the technical and constructional details of the bridge

are outlined, followed by a description of the instrumentation. At the end of each example, representative diagnostic results are presented and commented. The annexes are describing in detail sensors, data acquisition systems and algorithms for vibration-based damage detection used in SHM. Another comprehensive guideline was de
