Structural health monitoring of civil infrastructure systems

International Journal of Advance Research in Science and Engineering, 2016

There is a phenomenal rise in construction activities in the field of civil engineering in the recent years. Major structures like buildings, bridges, dams are subjected to severe loading and their performance is likely to change with time.It is therefore, necessary to check the performance of a structure through continuous monitoring by help of structural health monitoring.. Reduction of inspection costs, research, with the possibility to better understand the behavior of structures under dynamic loads, seismic protection, observation, in real or near real-time, of the structural response and of evolution of damage, so that it is possible to produce post-earthquake scenarios and support rescue operations, are the main advantages related to the implementation of such techniques.

The benefits of tracking, identifying, measuring features of interest from structure responses have endless applications for saving cost, time and improving safety. To date, structural health monitoring (SHM) has been extensively applied in several fields, such as aerospace, automotive, and mechanical engineering. However, the focus of this paper is to provide a comprehensive up-48 to-date review of civil engineering structures such as buildings, bridges, and other infrastructures. 49 For this reason, this article commences with a concise introduction to the fundamental definitions 50 of SHM. The next section presents the general concepts and factors that determine the best strategy 51 to be employed for SHM. Afterward, a thorough review of the most prevalent anomaly detection approaches, from classic techniques to advanced methods, is presented. Subsequently, some popular benchmarks, including laboratory specimens and real structures for validating the proposed methodologies, are demonstrated and discussed. Finally, the advantages and disadvantages of each method are summarized, which can be helpful in future studies.

Civil infrastructure such as bridges, buildings, dams, pipelines, rail tracks, etc., are normally designed to have long life spans. Changes in load characteristics, deterioration with age, environmental influences and random actions such as impacts, may cause damage in these structures. Structural Health Monitoring (SHM) has emerged as an efficient means of evaluating the health of a structure and detecting damage. If damage is detected during such an evaluation, appropriate retrofitting can be carried out to prevent collapse of the structure. Vibration based (VB) SHM methods, which give a global damage assessment, have attracted much attention in recent times. The principle of VB methods is that the vibration characteristics of a structure change when it is damaged and these changes can hence be used to detect structural damage. We have used VB SHM techniques to detect damage in a variety of structures such as (i) beam and plate structures which are important flexural members in bu...

The complexity in the health assessment of civil infrastructures, as it evolves over a long period of time, is briefly discussed. A simple problem can become very complex based on the current needs, sophistication required, and the technological advancements. To meet the current needs of locating defect spots and their severity accurately and efficiently, infrastructures are represented by finite elements. To increase the implementation potential, the stiffness parameters of all the elements are identified and tracked using only few noise-contaminated dynamic responses measured at small part of the infrastructure. To extract the required information, Kalman filter concept is integrated with other numerical schemes. An unscented Kalman filter (UKF) concept is developed for highly nonlinear dynamic systems. It is denoted as 3D UKF-UI-WGI. The basic UKF concept is improved in several ways. Instead of using one long duration time-history in one global iteration, very short duration time...

The aim of structural health monitoring for civil structures is not only detection of sudden damages due to extreme events but also monitoring progressive damages or structural performance under operational conditions. In particular, SHM can represent a valuable tool for detection of slowly evolving in time degradation phenomena, which can affect structural performance but whose effects can be hidden for long.

The term 'Structural Health Monitoring (SHM)' refers to continuous monitoring of a structure in order to track the changes in its dynamic characteristics and detect damage. In Civil/Structural Engineering, the majority of SHM applications are directed towards studying the response and damage from natural hazards, such as earthquakes and strong winds. The monitoring typically involves measuring continuously the vibrations of the structure by acceleration sensors. Some recent applications have also included GPS sensors, which provide superior accuracy for measuring displacements.Although a significant number of structures are now installed with SHM systems, the utilization of data for practical applications are still lacking. Some of the new findings resulting from SHM include the significant influence of environment on structural frequencies and damping, strong dependency of damping on amplitude and frequency, exponential decay in modal damping values with increasing building height, and the prevalence of 3D modes and non-proportional damping.A critical need in SHM is the simple tools and techniques for real-time data analysis and interpretation. Since data come continuously, the analysis cannot be done in batch mode; it should be done in real-time. This paper summarizes the latest developments in SHM, with emphasis on data analysis and damage detection. The topics discussed include real-time analysis techniques, noise reduction in ambient vibration data, utilization of wave propagation approach as an alternative to spectral analysis, inadequacy of modal parameters for damage detection, applications of Seismic Interferometry for data analysis, and identification and damage detection for historical structures.

Structural Health Monitoring is one of the preferred research topics in structural engineering but practical applications are still behind, at least in the civil sector. The paper is aimed at reviewing the main research achievements on the subject and to argue about the reasons because practical applications still encounter difficulties in becoming a standard practice in civil engineering. Structural health monitoring concepts and current design approaches are also discussed with consideration of the safety of monitored structures versus conventional non-monitored ones. Existing standards on structural monitoring and the need for the development of new standards integrating design, maintenance and management of constructed facilities are addressed.

Maximising the availability and productivity of onshore and offshore infrastructure and marine vessels, whilst operating them safely and with minimal impact on the environment, is of major concern to operators. Many such structures are unique, e.g. ships such as FPSOs have specific constraints, loading characteristics and damage consequences that make them different to other offshore installations and conventional ships, and often more challenging to maintain and operate. Market research shows that there is a need for efficient SHM which could facilitate structural, fatigue and corrosion analyses and underpin risk-based inspections to address the structural integrity of onshore and offshore structures. Radical developments in the telecommunication, sensor and data processing technologies are transforming the way that asset management is conceived and carried out. Sensors and structural health monitoring systems are increasingly becoming an integral part of new and existing buildings, bridges, offshore structures and installations, and vessels. Sensing arrays can be permanently connected to distributed management networks so that owners, users, and in general, all those involved in the management process - connected via the Internet - can query in real time condition and performance during construction and operation. Whereas today the structural engineer conceives the single building or bridge as a stand-alone project, in future it is likely that structures will be regarded as nodes of a complex infrastructure network. Design specifications, real-time operation, and any decision on maintenance, upgrading and reconstruction of the single node will reflect the management policy of the whole system, properly accounting for concepts such as cost, risk and sustainability and structural health monitoring will play a critical role in these transformed approaches. HeaMES 2019 provides an ideal platform for innovative industry and practitioners, leading researchers, technology developers, and supply chain partners to meet. Bringing the pioneering experts together, the conference aims to promote exchange of ideas, recent research and ways forward to application and commercialisation.

There is a phenomenal rise in construction activities in the field of civil engineering in the recent years. Major structures like buildings, bridges, dams and large trusses in industrial areas are subjected to severe loading and their performance is likely to change with time. It is therefore, necessary to check the performance of a structure through continuous monitoring by help of structural health monitoring. Structural Health Monitoring is a very multidisciplinary field, where a number of different skills (seismology, electronic and civil engineering, computer science) and institutions can work together in order to increase performance and reliability of such systems, whose promising perspectives seem to be almost clearly stated. The life of any structure can be increased by proper monitoring. This paper summarizes in brief the basic need of doing structural health monitoring in civil engineering.
