This book was released on 2017 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforced concrete bridge infrastructure is typically evaluated based on visually observed cracking/damage. However, traditional inspection procedures typically provide little-to-no insight into the remaining capacity of the inspected member. Although more rigorous methods have been proposed in the literature that offer quantitative insight into a structure’s health (with various levels of success), no procedure has been widely adopted. Furthermore, many of these proposed procedures have not been validated by experimental data. Experimental visual crack data were collected into a database to provide researchers and practitioners a means of developing and evaluating crack-based shear strength assessment procedures. The database has an emphasis on members which are similar in detail or scale to typical bridge elements. The database was subsequently used to evaluate a proposed mechanics-based damage assessment procedure based on an inverse solution of the modified compression field theory. In addition to visually observed crack characteristics (e.g., crack width and inclination), the proposed procedure relies upon basic material properties and design details. Average load proportions are estimated as a part of the procedure, therefore actual loading conditions (e.g., M/V∙d ratio for a beam) need not be known to calculate an estimate of an element’s residual capacity. Results from 420 analyses on beams from three experimental programs carried-out with the procedure show the potential of a mechanics-based procedure for the crack-based shear strength assessment of reinforced concrete bridge members. The average predicted-to-experimental ratio for normalized shear strength (i.e., capacity-in-use) was reasonable for two of the experimental series (0.98 – 1.17); however, results from the third group of beams trended much more conservatively (average predicted-to-experiment ratio of 1.43). Overall, the procedure is relatively simple and general in its application and shows promise as an evaluation tool.

This annual symposium was co-organised by the Cracow University of Technology. The topics covered include Analysis and Design, Sustainability, Durability, Structures, Materials, and Prefabrication. The fib, Fédération internationale du béton, is a not-for-profit association formed by 45 national member groups and approximately 1000 corporate and individual members. The fib’s mission is to develop at an international level the study of scientific and practical matters capable of advancing the technical, economic, aesthetic and environmental performance of concrete construction. The fib, was formed in 1998 by the merger of the Euro-International Committee for Concrete (the CEB) and the International Federation for Prestressing (the FIP). These predecessor organizations existed independently since 1953 and 1952, respectively.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents concepts, methods and techniques to examine symptoms of faults and failures of structures, systems and components and to monitor functional performance and structural integrity. The book is organized in five parts. Part A introduces the scope and application of technical diagnostics and gives a comprehensive overview of the physics of failure. Part B presents all relevant methods and techniques for diagnostics and monitoring: from stress, strain, vibration analysis, nondestructive evaluation, thermography and industrial radiology to computed tomography and subsurface microstructural analysis. Part C cores the principles and concepts of technical failure analysis, illustrates case studies, and outlines machinery diagnostics with an emphasis on tribological systems. Part D describes the application of structural health monitoring and performance control to plants and the technical infrastructure, including buildings, bridges, pipelines, electric power stations, offshore wind structures, and railway systems. And finally, Part E is an excursion on diagnostics in arts and culture. The book integrates knowledge of basic sciences and engineering disciplines with contributions from research institutions, academe, and industry, written by internationally known experts from various parts of the world, including Europe, Canada, India, Japan, and USA.

Book excerpt: This report presents a database of case histories of incidents due to impact, fire and scour for sixteen bridges in Wisconsin. It is intended to expand and use such case history and other relevant data in a future study to develop a decision support system. Such decision support system can aid bridge engineers take appropriate actions when rapid response is required in emergency cases such as major bridge damage or failure. The case history information presented here was assembled using available archived data from various DOT offices and through interviews with various active and retired staff of the WisDOT Districts and the City of Milwaukee. Each case history document includes information regarding any associated event, remediation, and past repair and maintenance. Essential structural and geometric data is also included with each case history document. As a part of this study, incident response procedures for WisDOT and the City of Milwaukee were developed through consultation with appropriate staff of those offices. The database is searchable with keywords and can be accessed through the web. User's manuals for both users and system administrators are included in the report.

Download or read book Handbook of Structural Life Assessment written by Raouf A. Ibrahim and published by John Wiley & Sons. This book was released on 2017-03-29 with total page 1016 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important, self-contained reference deals with structural life assessment (SLA) and structural health monitoring (SHM) in a combined form. SLA periodically evaluates the state and condition of a structural system and provides recommendations for possible maintenance actions or the end of structural service life. It is a diversified field and relies on the theories of fracture mechanics, fatigue damage process, and reliability theory. For common structures, their life assessment is not only governed by the theory of fracture mechanics and fatigue damage process, but by other factors such as corrosion, grounding, and sudden collision. On the other hand, SHM deals with the detection, prediction, and location of crack development online. Both SLA and SHM are combined in a unified and coherent treatment.
