Book Description
Authored by the most active scholars in their respective areas, this volume covers the most recent developments, both theoretical and applicative, in multi-disciplinary reliability evaluation areas, many of which are cutting-edge and not discussed elsewhere in book form.The broad coverage includes the latest thoughts on design for low probability and high consequence events like the failure of the World Trade Center as well as risk acceptability based on the Life Quality Index. Other chapters discuss the development of the performance-based design concept, and the generally overlooked area of the reliability evaluation of bridges and offshore structures. Since the finite element method is routinely used for structural analyses, emphasis is put on discussing reliability evaluation using finite elements including consideration of the mesh-free finite element method. Corrosion and fatigue reliability evaluation techniques are other urgent issues that are dealt with in depth. Risk-based optimization using lifecycle cost analysis is presented. Among the many additional included topics, a chapter is devoted to health assessment of existing structures, currently one of the most active research areas.

Book Description
Interest in the topic of structural reliability and optimal design has been rapidly growing in recent years. Besides, the field of numerical methods and artificial intelligence is experiencing a surge of new methods and the refinement of existing ones to expand opportunities to apply robust formulations to complex engineering problems. Today, more than ever, the field is receiving fresh ideas on how to face the challenges of finding a balance between cost and benefits that may lead towards the optimal design of systems. Recently, the probability density evolution method (PDEM) was proposed by Prof. Jie Li as an alternative way to obtain the stochastic and dynamic solution of the safety level of engineering systems under any kind of hazard. This work deals with the application of this powerful method to derive optimal design recommendations for large engineering systems under natural hazards. The three case studies illustrate to engineers and academic specialists how to strike a cost-effective balance in designing such systems.

Book Description
Increasing demand on improving the resiliency of modern structures and infrastructure requires ever more critical and complex designs. Therefore, the need for accurate and efficient approaches to assess uncertainties in loads, geometry, material properties, manufacturing processes, and operational environments has increased significantly. Reliability-based techniques help develop more accurate initial guidance for robust design and help to identify the sources of significant uncertainty in structural systems. Reliability-Based Analysis and Design of Structures and Infrastructure presents an overview of the methods of classical reliability analysis and design most associated with structural reliability. It also introduces more modern methods and advancements, and emphasizes the most useful methods and techniques used in reliability and risk studies, while elaborating their practical applications and limitations rather than detailed derivations. Features: Provides a practical and comprehensive overview of reliability and risk analysis and design techniques. Introduces resilient and smart structures/infrastructure that will lead to more reliable and sustainable societies. Considers loss elimination, risk management and life-cycle asset management as related to infrastructure projects. Introduces probability theory, statistical methods, and reliability analysis methods. Reliability-Based Analysis and Design of Structures and Infrastructure is suitable for researchers and practicing engineers, as well as upper-level students taking related courses in structural reliability analysis and design.

Book Description
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.
