Available in PDF, EPUB and Kindle. Book excerpt: Civil infrastructure undergoes various and consistent loads during its lifecycles, such as wind, seismic loads, and etc. The declining condition, the performance of the structure and the potential consequential damages due to the loads become critical in most industrialized countries (Spencer et al., 2016). Therefore, during decades, efforts have been made to understand the serviceability of the structure. Because the behavior of a structure depends on stiffness and mass distribution, the structure may have been examined through finite element models. However, because the aged structure show changed condition, such a method often fail to predict the fundamental characteristics of the structure precisely. Alternatively, the driving interests have been made to develop a non-destructive tool that can estimate the characteristics of an in-service structure, which one among various is known as Structural Health Monitoring.

This book was released on 2012 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Civil engineering structures inevitably subject to the adverse effects of environment erosion, material aging, fatigue, long-term effect of loadings, and natural disasters etc., which result in an accumulation of damage in structures. The structural deterioration has become a worldwide concern as it is a hidden danger which may cause sudden break or collapse of the structure. Structural Health Monitoring (SHM) has been attracting enormous research efforts in structural engineering because it targets at monitoring structural conditions to prevent catastrophic failure, and to provide quantitative data for engineers and infrastructure owners to design reliable and economical asset management plans. Many SHM systems have been installed on large-scale structures worldwide, however, a great deal of research is still needed for developing more reliable and applicable real-time SHM systems. A critical issue needs to be well addressed is the development of a vibration-based system identification method and a damage detection technique that are applicable to the real-time SHM under operational conditions. The research carried out in this thesis focuses on developing the vibration-based system identification technique and damage detection method that are applicable to the SHM of structures under ambient excitations. It consists of: (1) applicability of the widely used output-only system identification methods including time domain methods, frequency domain methods and time-frequency domain methods is comparatively studied. Variability of modal parameter identification produced by using various methods is quantified through analysing the ambient vibration response of an example beam indicating that on average a 2% to 3% error is generated in natural frequency identification, which should be accounted in damage detection...

Download or read book Ambient Vibration Monitoring written by Helmut Wenzel and published by John Wiley & Sons. This book was released on 2005-12-13 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-operation vibration monitoring for complex mechanical structures and rotating machines is of key importance in many industrial areas such as aeronautics (wings and other structures subject to strength), automobile (gearbox mounting with a sports car body), rail transportation, power engineering (rotating machines, core and pipes of nuclear power plants), and civil engineering (large buildings subject to hurricanes or earthquakes, bridges, dams, offshore structures). Tools for the detection and the diagnosis of small changes in vibratory characteristics are particularly useful to set up a preventive maintenance policy based on the actual evolution of the state of the monitored machine or structure, as opposed to systematic a priori planning. Ambient Vibration Monitoring is the backbone of such structural assessment monitoring and control. It provides the possibility to gain useful data under ambient conditions for the assessment of structures and components. Written by a widely respected authority in this area, Ambient Vibration Monitoring describes the current practice of ambient vibration methodologies illustrated by a number of practical examples. Designed to aid the practical engineer with their understanding of the topic, it is the culmination of many years of practical research and includes numerous ‘real world’ examples. It also provides information on applicable solutions. This book will enable not only practitioners (in civil, mechanical and aerospace engineering), but also researchers and students, to learn more about the theory and practical applications of this subject.

This book was released on 2008 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Civil structures undergo progressive deterioration due to ageing under the effects of environmental conditions. This deterioration has become a worldwide concern. In addition, natural and man-made hazards such as earthquakes, hurricanes, and explosions can also cause structural damages or exacerbate existing damage. Vibration-based structural damage identification and health monitoring has been the subject of significant research in structural engineering over the past decade. The research work presented in this dissertation consists of: (1) a comparative study of output-only system identification techniques as applied to the Alfred Zampa Memorial Bridge based on dynamic field test data, through which the performance of different output-only system identification methods applied to the bridge vibration data and corresponding to different excitation sources is investigated; (2) development of a simulation framework for wind-induced ambient vibration response of Vincent Thomas Bridge using a detailed three-dimensional finite element model of the bridge and a state-of-the-art stochastic wind excitation model, which provides a validated framework to study the effects of realistic damage scenarios in long-span cable-supported bridges on their identified modal parameters; (3) damage identification of a full-scale seven-story reinforced concrete building slice tested on the UCSD-NEES shake table using a sensitivity-based finite element model updating strategy based on the modal parameters identified from ambient vibration data; (4) development and implementation of a state-of-the-art long-term continuous monitoring system on the Voigt Bridge Testbed, which will serve as a live laboratory for structural health monitoring technologies; (5) development of an automated system identification procedure for extracting modal parameters of the Voigt Bridge as a function of time; and (6) investigation of the environmental effects on the identified modal parameters of the Voigt Bridge and objective criterion for damage detection under varying environmental conditions. The research work presented and the results obtained in this dissertation contribute significantly to the development of robust and reliable vibration-based structural health monitoring systems for large and complex real-world structures.
