This book was released on 2020 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridge - girder deterioration model is formed based on diffusivity process, corrosion development, and cracks propagation. The chloride diffusivity is studied based on previous researches0́9 experimental work while corrosion penetration is analyzed based on mathematical model. Corrosion products cause cracks then spalling. Therefore, in the few decades, the utilize of fiber-reinforced polymer (FRP) materials to strengthen highway bridges has obtained in popularity. sensible cost, speed and ease of installation, and limited disruption of the use of the structure have shared to the adoption of FRP systems over other strengthening options. In order to reduce the corrosion with the bridge deterioration. Fiber Reinforced Polymer (FRP) is one of the top solutions to reduce corrosion and strengthen bridge - girders, by placing FRP on the side(s) of the reinforced concrete beam and reduce the influence of chloride diffusivity through reinforced concrete. Thus, the deterioration with reinforced concrete based on corrosion with section warped with FRP is less than with the corrosion of reinforced concrete section unwrapped with FRP. The objective of this study is to develop a reliability - deterioration model based on corrosion in steel, concrete cover spalling, and FRP debonding. The reliability is reduced due to two independent deterioration factors that developed simultaneously with Life Cycle Time (LCT). The corrosion in steel rebar is the first deterioration factor that causes reduction in flexural moment capacity, and spalling. Moreover, the second deterioration factor is the surrounded environment that may causes FRP debonding. Monti Carlo Simulation (MCS) of reliability-based deterioration model is programmed and used in order to compute failure probability by using FORTRAN 90 to analyze the bridge 0́3 girder model including all design parameters.

This book was released on 1999 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, life-cycle cost analysis is gradually becoming a requirement for bridge design, inspection, repair and replacement decisions. Bridges are designed to function over long periods of time, but can experience changes in both resistance and applied loads which are time-variant. Current reliability-based codes for buildings and bridges are largely limited to individual structural component checks, and do not consider the potential damaged states of a structural system and the ability of the damaged system to continue to carry loads. Furthermore, current codes do not entail the prediction of the failure time of deteriorating structural systems under time-varying loads. Although the need for the application of time-variant system reliability methods to bridge life-cycle cost prediction is becoming increasingly recognized in the U.S., most reliability studies on reinforced concrete bridges do not consider the time dependence of the resistance or post-failure behavior of bridge elements. In this study, the time-variant system reliability of reinforced concrete highway girder bridges subjected to time-dependent load and resistance is investigated. The approach, which is based on combining adaptive importance sampling and numerical integration, is suitable for predicting the reliability of reinforced concrete bridges under environmental stressors such as corrosion. The effects of corrosion initiation time and rate on time-variant strength of reinforced concrete beams are illustrated using Monte Carlo simulation. An existing reinforced concrete T-beam bridge located near Pueblo, Colorado, is investigated. A comparison of reliability estimates for several system models is given, including the influence of correlation among initial girder strengths. Post-failure behavior of components and load redistribution effects are also considered. The influence of inspection updating on time-variant system failure probability is illustrated using Bayesian-based numerical integration. Optimal inspection/repair strategies are included which are based on minimum lifecycle cost within prescribed reliability constraints. The results can be used as a guide for the selection of system models for bridge reliability analysis, identification of critical girders in a bridge system, and for the development of optimal reliability-based maintenance strategies for reinforced concrete highway bridges.

Available in PDF, EPUB and Kindle. Book excerpt: STRUCTURAL RELIABILITY Discover a new and innovative approach to structural reliability from two authoritative and accomplished authors The subject of structural reliability, which deals with the problems of evaluating the safety and risk posed by a wide variety of structures, has grown rapidly over the last four decades. And while the First-Order Reliability Method is principally used by most textbooks on this subject, other approaches have identified some of the limitations of that method. In Structural Reliability: Approaches from Perspectives of Statistical Moments, accomplished engineers and authors Yan-Gang Zhao and Dr. Zhao-Hui Lu, deliver a concise and insightful exploration of an alternative and innovative approach to structural reliability. Called the Methods of Moment, the authors’ approach is based on the information of statistical moments of basic random variables and the performance function. The Methods of Moment approach facilitates structural reliability analysis and reliability-based design and can be extended to other engineering disciplines, yielding further insights into challenging problems involving randomness. Readers will also benefit from the inclusion of: A thorough introduction to the measures of structural safety, including uncertainties in structural design, deterministic measures of safety, and probabilistic measures of safety An exploration of the fundamentals of structural reliability theory, including the performance function and failure probability A practical discussion of moment evaluation for performance functions, including moment computation for both explicit and implicit performance functions A concise treatment of direct methods of moment, including the third- and fourth-moment reliability methods Perfect for professors, researchers, and graduate students in civil engineering, Structural Reliability: Approaches from Perspectives of Statistical Moments will also earn a place in the libraries of professionals and students working or studying in mechanical engineering, aerospace and aeronautics engineering, marine and offshore engineering, ship engineering, and applied mechanics.

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.
