Download or read book Management Maintenance and Strengthening of Concrete Structures written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2002-01-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the result of the work of the former FIP Commission 10: Management and strengthening of concrete structures, which replaced to the former FIP Commission 10: Maintenance, operation and use in 1995. The former CEB Commission V: Operation and Use and in particular its Task Group 5.4: Assessment, maintenance and repair also played a role in this report. When in 1998 the FIP merged with the CEB to form the fib, the well advanced writing was completed by a small editorial group. The purpose of the report is twofold: to give an overview of the issues relating to the management of concrete structures in general and to add details about assessment and remedial action, as these are important technical aspects of management and maintenance systems. The more general aspects of asset management are dealt with in Chapter 1, aimed at owners and decision-makers. Chapters 2 and 3, aimed at consultants and contractors, deal with decision-making in the assessment process. A review of remediation techniques is given in Chapter 3, intended to help in the selection of remedial actions rather than in their execution. The report also includes some significant appendices regarding load testing, monitoring and fire, and also special considerations related to seismic retrofitting. Appendix 1 offers keywords that the various actors in this field could use for a common language.

Download or read book Interim Report on Concrete Degradation Mechanisms and Online Monitoring Techniques written by and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing fleets of nuclear power plants in the United States have initial operating licenses of 40 years, though most these plants have applied for and received license extensions. As plant structures, systems, and components age, their useful life--considering both structural integrity and performance--is reduced as a result of deterioration of the materials. The online monitoring of concrete structure conducted under the Advanced Instrumentation, Information, and Control Technologies Pathway of the Light Water Reactor Sustainability program at Idaho National Laboratory will develop and demonstrate concrete structures health monitoring capabilities. Assessment and management of aging concrete structures in nuclear plants require a more systematic approach than simple reliance on existing code margins of safety. Therefore, the structural health monitoring is required to produce actionable information regarding structural integrity that supports operational and maintenance decisions. Through this research project, several national laboratories and Vanderbilt University proposes to develop a framework of research activities for the health monitoring of nuclear power plant concrete structures that includes integration of four elements--damage modeling, monitoring, data analytics, and uncertainty quantification. This report briefly discusses available techniques and ongoing challenges in each of the four elements of the proposed framework with emphasis on degradation mechanisms and online monitoring techniques.

Download or read book Performance Based Specifications and Control of Concrete Durability written by Hans Beushausen and published by Springer. This book was released on 2015-09-24 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work gives an overview of significant research from recent years concerning performance-based design and quality control for concrete durability and its implementation. In engineering practice, performance approaches are often still used in combination with prescriptive requirements. This is largely because, for most durability test methods, sufficient practical experience still has to be gained before engineers and owners are prepared to fully rely on them. This book, compiled by RILEM TC 230-PSC, is intended to assist efforts to successfully build the foundation for the full implementation of performance-based approaches through the exchange of relevant knowledge and experience between researchers and practitioners worldwide.

This book was released on 2011-03-10 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is one of the most intriguing structural materials and the only one that is truly renewable. Along with stone, wood is the oldest structural material on the planet and has been extensively used throughout human history. Due to its aesthetical value and positive environmental impact, wood has experienced a renaissance in construction. As a biodegradable, hygroscopic, non-isotropic material, wood presents special challenges for a professional and requires through knowledge ranging from biology to continuum mechanics. This state-of-the-art report reflects the current knowledge in the area of in situ assessment of the physical and mechanical properties of wood structures. Nondestructive, semi-destructive and destructive methods are described in a systematic manner where technology, equipment and limitations are discussed. Some of the discussed methods are used in other materials such as masonry and concrete. Most of the methods, however, are specific to wood and special qualifications are required to understand and apply these methods effectively. Existing methods are constantly improved and new methods are being developed. This report includes methods that are used in practice or have shown significant promise and have a body of knowledge that supports statements made in this report. This is a useable tool for professionals, researchers, educators and students
