Book Synopsis Structural Health Monitoring of Long-Span Suspension Bridges by : You Lin Xu
Download or read book Structural Health Monitoring of Long-Span Suspension Bridges written by You Lin Xu and published by CRC Press. This book was released on 2011-08-31 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long span suspension bridges cost billions. In recent decades, structural health monitoring systems have been developed to measure the loading environment and responses of these bridges in order to assess serviceability and safety while tracking the symptoms of operational incidents and potential damage. This helps ensure the bridge functions properly during a long service life and guards against catastrophic failure under extreme events. Although these systems have achieved some success, this cutting-edge technology involves many complex topics that present challenges to students, researchers, and engineers alike. Systematically introducing the fundamentals and outlining the advanced technologies for achieving effective long-term monitoring, Structural Health Monitoring of Long-Span Suspension Bridges covers: The design of structural health monitoring systems Finite element modelling and system identification Highway loading monitoring and effects Railway loading monitoring and effects Temperature monitoring and thermal behaviour Wind monitoring and effects Seismic monitoring and effects SHMS-based rating method for long span bridge inspection and maintenance Structural damage detection and test-bed establishment These are applied in a rigorous case study, using more than ten years' worth of data, to the Tsing Ma suspension bridge in Hong Kong to examine their effectiveness in the operational performance of a real bridge. The Tsing Ma bridge is the world's longest suspension bridge to carry both a highway and railway, and is located in one of the world’s most active typhoon regions. Bridging the gap between theory and practice, this is an ideal reference book for students, researchers, and engineering practitioners.
Book Synopsis Dynamic Methods for Damage Detection in Structures by : Antonino Morassi
Download or read book Dynamic Methods for Damage Detection in Structures written by Antonino Morassi and published by Springer Science & Business Media. This book was released on 2008-12-11 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non destructive testing aimed at monitoring, structural identification and di- nostics is of strategic importance in many branches of civil and mechanical - gineering. This type of tests is widely practiced and directly affects topical issues regarding the design of new buildings and the repair and monitoring of existing ones. The load bearing capacity of a structure can now be evaluated using well established mechanical modelling methods aided by computing facilities of great capability. However, to ensure reliable results, models must be calibrated with - curate information on the characteristics of materials and structural components. To this end, non destructive techniques are a useful tool from several points of view. Particularly, by measuring structural response, they provide guidance on the validation of structural descriptions or of the mathematical models of material behaviour. Diagnostic engineering is a crucial area for the application of non destructive testing methods. Repeated tests over time can indicate the emergence of p- sible damage occurring during the structure's lifetime and provide quantitative estimates of the level of residual safety.
Book Synopsis Innovative Methods and Materials in Structural Health Monitoring of Civil Infrastructures by : Raffaele Zinno
Download or read book Innovative Methods and Materials in Structural Health Monitoring of Civil Infrastructures written by Raffaele Zinno and published by MDPI. This book was released on 2021-09-02 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, when elements in structures were composed of perishable materials, such as wood, the maintenance of houses, bridges, etc., was considered of vital importance for their safe use and to preserve their efficiency. With the advent of materials such as reinforced concrete and steel, given their relatively long useful life, periodic and constant maintenance has often been considered a secondary concern. When it was realized that even for structures fabricated with these materials that the useful life has an end and that it was being approached, planning maintenance became an important and non-negligible aspect. Thus, the concept of structural health monitoring (SHM) was introduced, designed, and implemented as a multidisciplinary method. Computational mechanics, static and dynamic analysis of structures, electronics, sensors, and, recently, the Internet of Things (IoT) and artificial intelligence (AI) are required, but it is also important to consider new materials, especially those with intrinsic self-diagnosis characteristics, and to use measurement and survey methods typical of modern geomatics, such as satellite surveys and highly sophisticated laser tools.

During the past two decades, there have been significant advances in the sensing technologies employed in long-span bridge health monitoring. However, interpretation of the massive monitoring data is still lagging behind. This book establishes a series of measurement interpretation frameworks that focus on bridge site environmental conditions, and global and local responses of suspension bridges. Using the proposed frameworks, it subsequently offers new insights into the structural behaviors of long-span suspension bridges. As a valuable resource for researchers, scientists and engineers in the field of bridge structural health monitoring, it provides essential information, methods, and practical algorithms that can facilitate in-service bridge performance assessments.
Book Synopsis Construction Control of Cable-stayed Bridges by : José Antonio Lozano Galant
Download or read book Construction Control of Cable-stayed Bridges written by José Antonio Lozano Galant and published by . This book was released on 2014 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a study of the simulation of cable-stayed bridges built on temporary supports focused on their response during construction and in service. To simulate the behavior during construction, a set of four different algorithms has been developed to deal with initial design (Backward Algorithm), updating the tensioning process when deviations on site are measured (Forward Algorithm), optimization processes (Direct Algorithm) and time-dependent phenomena effects (Forward-Direct Algorithm). These algorithms were validated by comparing their results with those obtained by two commercial codes. On the other hand, new criteria have been proposed to include the effects of the staggered erection of the superstructure and the time-dependent phenomena effects into the definition of the Objective Service State. To illustrate the application of these methods, a set of academic and actual structures is analyzed. For a more accurate simulation of the actual response of structures on site, a new Structural System Identification (SSI) method (Observability method) is developed. This method is based on the information provided by the monitoring of a static non-destructive test. After validating the results of this method with three alternative methods proposed in the literature, it is applied to complex structures (such as singular buildings and cable-stayed bridges). A parametric analysis is presented to illustrate the role that the uncertainty of each parameter of a real cable-stayed bridge plays in its behavior during construction and in service. Furthermore, modifications of this method to deal with damages, actual boundary conditions, temperature effects, and dynamic excitation tests are presented. The developed SSI method has also lead to the development of a very powerful mathematical tool to deal with polyrational systems of equations. This tool presents a number of applications in many fields of science and engineering (such as transportation, hydraulics or energy power distribution, among many others). To define the minimum measurement set of measurements required for an adequate system identification, a new and innovative graphical tool (observability tree) is developed. To ease the representation of these trees, a set of guidelines is proposed for beam and cable-stayed bridges. To minimize the degrees of freedom to be monitored on site for system identification with actual loads, a new application of the Maxwell's theorem has been proposed. To this end, the utilization of information from alternative load cases, boundary conditions and construction stages is also presented. The results of the proposed methods have led to significant conclusions regarding the response of the cable-stayed bridges built on temporary supports both during construction and in service as well as the importance of their construction control by SSI techniques. From these conclusions, a set of guidelines has been proposed to address the erection of the superstructure, to estimate the appropriate time to define the stay cable forces in service in concrete cable-stay bridges considering time-dependent phenomena effects, to define a measurement set for an adequate SSI and to minimize the points to be monitored.
