Management of Deteriorating Concrete Structures by George Somerville Pdf

Demolishing and rebuilding is becoming less and less of an option, and developing trends such as the growth of PFI are directing attention to whole life costing. With the relentless drive towards greater sustainability, proper asset management of the existing infrastructure will become increasingly important in the future. This authoritative book draws together deterioration and repair/remediation with practical asset management. Despite the wealth of information there is a lack of clear guidance on how to carry out a practical assessment of concrete structures and manage repair in the field. Accordingly, this book gives solid practical guidance on assessment, and outlines when and how to act. The focus is on engineering aspects and decision-making, in terms of perspective, procedures and principles, while giving references for matters of detail such as test methods and the mechanisms of deterioration. It links deterioration to deficiencies in design, detailing, materials and construction quality. It then gives examples of how asset management systems have evolved for different types of structure in different countries. It shows how to move forward from inspection and diagnosis, through different methods of damage or structural assessment, to the selection of the optimum method of repair or remedial action. The concept of progressive screening is proposed – that is, only going as far as is necessary to reach a decision with confidence. The author has drawn on over thirty years experience on concrete durability and, in particular, on his involvement in three recent European-funded projects, involving collaboration between the owners of structures and researchers.

Concrete Structure Management - Guide to Ownership and Good Practice by fib Fédération internationale du béton Pdf

Construction projects are undertaken to meet a variety of business, service and aspirational objectives and needs. The success of a building or an element of infrastructure depends on how well it meets the owner's needs and interests or those of the users. Recent changes in owner attitudes to construction are reflected in an increasing interest in through-life costs, i.e. not only the capital costs of construction but also the operational costs associated with a structure's functional performance for a defined life span. The owner can greatly improve the likelihood of achieving the value they seek from the facility by being intimately and effectively involved in the definition of performance requirements at the start of the construction procurement process. The objective of fib Bulletin 44 is to provide guidance to owners of concrete structures on: the management of their concrete structures (buildings and infrastructure) as part of their business goals or the service objectives of their organization; best practice in the management of concrete structures; their responsibilities with respect to the management of their concrete structures; the wider context and issues of service life design; information and direction needed by the supporting professional team of architects, engineers, specifiers, contractors and others. This Guide also provides background information on topics such as deterioration processes and technical procedures used for the management of concrete structures, including reference to international standards for the protection and repair of concrete structures. These activities are illustrated by application examples/case histories and by a section addressing frequently asked questions. A brief review is made of some potential future developments.

Structural Concrete Textbook, Volume 5 by fib Fédération internationale du béton Pdf

The third edition of the Structural Concrete Textbook is an extensive revision that reflects advances in knowledge and technology over the past decade. It was prepared in the intermediate period from the CEP-FIP Model Code 1990 (MC90) tofib Model Code for Concrete Structures 2010 (MC2010), and as such incorporates a significant amount of information that has been already finalized for MC2010, while keeping some material from MC90 that was not yet modified considerably. The objective of the textbook is to give detailed information on a wide range of concrete engineering from selection of appropriate structural system and also materials, through design and execution and finally behaviour in use. The revised fib Structural Concrete Textbook covers the following main topics: phases of design process, conceptual design, short and long term properties of conventional concrete (including creep, shrinkage, fatigue and temperature influences), special types of concretes (such as self compacting concrete, architectural concrete, fibre reinforced concrete, high and ultra high performance concrete), properties of reinforcing and prestressing materials, bond, tension stiffening, moment-curvature, confining effect, dowel action, aggregate interlock; structural analysis (with or without time dependent effects), definition of limit states, control of cracking and deformations, design for moment, shear or torsion, buckling, fatigue, anchorages, splices, detailing; design for durability (including service life design aspects, deterioration mechanisms, modelling of deterioration mechanisms, environmental influences, influences of design and execution on durability); fire design (including changes in material and structural properties, spalling, degree of deterioration), member design (linear members and slabs with reinforcement layout, deep beams); management, assessment, maintenance, repair (including, conservation strategies, risk management, types of interventions) as well as aspects of execution (quality assurance), formwork and curing. The updated textbook provides the basics of material and structural behaviour and the fundamental knowledge needed for the design, assessment or retrofitting of concrete structures. It will be essential reading material for graduate students in the field of structural concrete, and also assist designers and consultants in understanding the background to the rules they apply in their practice. Furthermore, it should prove particularly valuable to users of the new editions of Eurocode 2 for concrete buildings, bridges and container structures, which are based only partly on MC90 and partly on more recent knowledge which was not included in the 1999 edition of the textbook.

Condition Control and Assessment of Reinforced Concrete Structures Exposed to Corrosive Environments (carbonation/chlorides) by fib Fédération internationale du béton Pdf

For the ongoing condition assessment of concrete structures, it is necessary to identify the extent, nature, cause and prognosis of any deterioration using a range of tools and methods, including prediction models. Combined with the original design and construction details, this gives a vast amount of information over a long time period. A framework concept is therefore needed to process the entirety of the information in order to make sound investment decisions on future maintenance management. To provide such a framework, fib Bulletin 59 summarizes information published infib Bulletins 17, 22, 34 and 44 relevant to the control and assessment of reinforced concrete structures, and develops a practical concept of how, when and where to control the condition of an existing concrete structure in order to facilitate structural management. Thus it gives a basis for processing relevant information in order to make decisions on the appropriate course of action for condition control.

Guide for Protection and Repair of Concrete Structures by FIB – International Federation for Structural Concrete Pdf

The idea of preparing a technical document for the repairs and interventions upon concrete structures goes back to the former fib COM5: Structural Service Life Aspects, being the goal of the then TG5.9. After a long period of reduced activity, and taking into account the reorganization of fib commissions that meanwhile took place, on June 2017 a different approach was proposed to push forward the task of TG8.1 (formerly TG5.9). The (new) goal of TG 8.1 was to deliver a ‘how-to-do’ guide, gathering together protection, repair, and strengthening techniques for concrete structures. Chapters are intended to provide both guidelines and case-studies, serving as support to the application of fib MC2020 pre-normative specifications. Each chapter was written by an editorial team comprising desirably at least a researcher, a designer and a contractor. Templates have been prepared in order to harmonize the contents and the presentation of the different methods. Following the writing process, chapters were reviewed by experts and, after amendments by the authors, they underwent a second review process by COM8 and TG3.4 members, as well as by different practitioners. For each protection, repair and strengthening method addressed in this guide, readers have a description of when to adopt it, which materials and systems are required, which techniques are available, and what kind of equipment is needed. It then presents a summary of stakeholders’ roles and qualifications, design guidelines referring to most relevant codes and references, the intervention procedure, quality control measures and monitoring and maintenance activities. Due to the extent of the guide, it was decided to publish it as bulletin 102, addressing protection and repair methods, and bulletin 103, addressing strengthening methods. We would like to thank the authors, reviewers and members of COM8 and TG3.4 for their work in developing this fib Bulletin, which we hope will be useful for professionals working in the field of existing concrete structures, especially those concerned with life-cycle management and conservation activities. As noted above, this Bulletin is also intended to act as a background and supporting document to the next edition of the fib Model Code for Concrete Structures, which is currently under development under the auspices of TG10.1 with the working title of "fib Model Code 2020".

Preservation of Historic Concrete by Paul E. Gaudette Pdf

This edition will have color illustrations. Concrete is an extraordinarily versatile building material used for utilitarian, ornamental, and monumental structures since ancient times. Composed of a mixture of sand, gravel, crushed stone, or other coarse material, bound together with lime or cement, concrete undergoes a chemical reaction and hardens when water is added. Inserting reinforcement adds tensile strength to structural concrete elements. The use of reinforcement contributes significantly to the range and size of building and structure types that can be constructed with concrete. This Brief provides an overview of the history of concrete and its popularization in the United States, surveys the principal causes and modes of concrete deterioration, and outlines approaches to repair and protection that are appropriate to historic concrete. In the context of this Brief, historic concrete is considered to be concrete used in construction of structures of historical, architectural, or engineering interest, whether those structures are old or relatively new.
