This book was released on 2010-01-01 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the advantages of reinforced concrete (RC) structures is its durability. However, when they are exposed to aggressive environments (e.g., chloride penetration) and cyclic loading, its performance can be significantly affected. Modeling deterioration produced by chloride penetration is useful to ensure optimal levels of serviceability and safety. The main purpose of this book is to propose a new model for lifetime assessment of RC structures subjected to deterioration produced by the combined action of corrosion and fatigue. The formulation of the model is based on a state of the art review on modeling of this kind of deterioration. Furthermore, taking into account the importance of the uncertainty related to the whole deterioration process, this book also presents a stochastic framework for this problem. Finally, several practical examples illustrate the effects of the corrosion-fatigue process in the reduction of life-cycle of RC structures.

Download or read book Structures and Infrastructure Systems written by Dan M. Frangopol and published by Routledge. This book was released on 2019-12-18 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our knowledge to model, design, analyse, maintain, manage and predict the life-cycle performance of infrastructure systems is continually growing. However, the complexity of these systems continues to increase and an integrated approach is necessary to understand the effect of technological, environmental, economic, social, and political interactions on the life-cycle performance of engineering infrastructure. In order to accomplish this, methods have to be developed to systematically analyse structure and infrastructure systems, and models have to be formulated for evaluating and comparing the risks and benefits associated with various alternatives. Civil engineers must maximize the life-cycle benefits of these systems to serve the needs of our society by selecting the best balance of the safety, economy, resilience and sustainability requirements despite imperfect information and knowledge. Within the context of this book, the necessary concepts are introduced and illustrated with applications to civil and marine structures. This book is intended for an audience of researchers and practitioners world‐wide with a background in civil and marine engineering, as well as people working in infrastructure maintenance, management, cost and optimization analysis. The chapters originally published as articles in Structure and Infrastructure Engineering.

Download or read book Service Life Modelling of R C Highway Structures Exposed to Chlorides written by Beatriz Martin-Perez and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The detrimental effect of chloride-induced corrosion on the service life of reinforced concrete highway structures highlights the need for the development of mathematical models that describe the mechanisms of corrosion and damage build-up in reinforced concrete. The objective of this study was to develop a generalized computer model for the prediction of service life of reinforced concrete highway structures exposed to de-icing salts. The mathematical formulation idealized the corrosion sequence as a two-stage process: an initiation stage, during which chloride ions penetrate to the reinforcing steel layer and depassivate it, and a propagation stage, in which active corrosion takes place until cracking of the concrete cover has occurred. In modelling chloride transport to the reinforcing steel (initiation stage), a modified version of Fick's 2'nd' law was used, in which the processes of diffusion, chloride binding, and convection due to water movement were taken into account. The migration of chloride ions through concrete was coupled with moisture diffusion and heat transfer within concrete. Corrosion was assumed to initiate when the chloride concentration at the steel layer reaches a specified threshold value. To model the stage corresponding to active corrosion (propagation stage), the rate of corrosion was linked to oxygen availability at the cathodic areas. The governing partial differential equations that idealize the problem were solved numerically in space as a boundary-value problem and in time as an initial-value problem by means of a two-dimensional finite element formulation, in which appropriate boundary conditions were enforced to simulate the seasonal variations in exposure conditions. A time-step integration procedure was applied to determine the variation in time of the various species concentrations at the level of the reinforcement. To assess the mechanical damage resulting from the expansion of the corrosion products, an equivalent uniform internal pressure was applied around the steel/concrete interface, and the resulting state of stress in the surrounding concrete was evaluated by means of an elastic analysis. The numerical performance of the model was examined in few example cases to assess the relative importance of the different mechanisms considered on the service life of reinforced concrete structures exposed to chloride environments.

Available in PDF, EPUB and Kindle. Book excerpt: Reinforced concrete has the potential to be very durable and capable of withstanding a variety of adverse environmental conditions. However, failures in the structures do still occur as a result of premature reinforcement corrosion. In this authoritative book the fundamental aspects of this complex process are analysed; focusing on corrosion of the reinforcing steel, and looking particularly, at new scientific and technological developments. Monitoring techniques, including the newly developed online-monitoring, are examined, as well as the numerical methods used to simulate corrosion and perform parameter studies. The influence of composition and microstructure of concrete on corrosion behaviour is explored. The second half of the book, which deals with corrosion prevention methods, starts with a discussion on stainless steels as reinforcement materials. There are comprehensive reviews of the use of surface treatments and coatings, of the application of corrosion inhibitors and of the application of electrochemical techniques. In each case the necessary scientific fundamentals are explained and practical instances of use are looked at. This is an invaluable guide for engineers, materials scientists and researchers in the field of structural concrete. Fundamental aspects of corrosion in concrete are analysed in detail Explores how to minimise the effects of corrosion in concrete Invaluable guide for engineers, materials scientists and researchers in the field of structural concrete

Download or read book A Multi physics Corrosion Induced Deterioration Framework for Durability Performance Management of Reinforced Concrete Structures written by Jie Wu (Researcher in building information modeling) and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforced structures are continuously at risk from corrosion, fatigue, and other deterioration processes over a decades-long lifetime. During the last decades, various numerical models have been developed that capture the corrosion-induced deterioration of reinforced concrete structures over time. While these models are useful, the practice of numerical deterioration modeling remains largely foreign to engineers, building owners, and managers. This thesis establishes a framework to enable durability performance management of reinforced concrete structures subjected to corrosion-induced deterioration using multi-physics models that are based on fundamental material characteristics and environmental exposures. This framework first develops a method to build multi-physics deterioration models rapidly and efficiently with limited human intervention, and a method to interpret and present the simulation results in a straightforward manner for decision makers. This framework also addresses the need for a realistic model of initiation of chloride-induced corrosion by developing a method to assign critical chloride content more appropriately in numerical models by explicitly considering both spatial variation and time-dependency. A three-dimensional modeling framework of carbonation-induced deterioration of reinforced concrete that covers both the initiation and propagation phases of corrosion is also developed in this thesis and integrated with chloride-induced corrosion to more realistically model reinforced concrete elements with multiple longitudinal rebars and stirrups. Finally, using neural network model as surrogates for multi-physics deterioration models of reinforced concrete service life is developed and evaluated in this thesis to enable faster computational simulations of reinforced concrete service life that are statistically equivalent to simulations based on highly complex multi-physics deterioration models.

This book was released on 2006-01-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 34 addresses Service Life Design (SLD) for plain concrete, reinforced concrete and pre-stressed concrete structures, with a special focus on design provisions for managing the adverse effects of degradation. Its objective is to identify agreed durability related models and to prepare the framework for standardization of performance based design approaches. Four different options for SLD are given: - a full probabilistic approach, - a semi probabilistic approach (partial factor design), - deemed to satisfy rules, - avoidance of deterioration. The service life design approaches described in this document may be applied for the design of new structures, for updating the service life design if the structure exists and real material properties and/or the interaction of environment and structure can be measured (real concrete covers, carbonation depths), and for calculating residual service life. The bulletin is divided into five chapters: 1. General 2. Basis of design 3. Verification of Service Life Design 4. Execution and its quality management 5. Maintenance and condition control It also includes four informative annexes, which give background information and examples of procedures and deterioration models for the application in SLD. The format of Bulletin 34 follows the CEB-FIP tradition for Model Codes: the main provisions are given on the right-hand side of the page, and on the left-hand side, the comments. Note: An Italian translation of Bulletin 34 is also available; contact us for further details.
