This book presents the latest research findings in the field of maintenance and safety of aging infrastructure. The invited contributions provide an overview of the use of advanced computational and/or experimental techniques in damage and vulnerability assessment as well as maintenance and retrofitting of aging structures and infrastructures such as buildings, bridges, lifelines and ships. Cost-efficient maintenance and management of civil infrastructure requires balanced consideration of both structural performance and the total cost accrued over the entire life-cycle considering uncertainties. In this context, major topics treated in this book include aging structures, climate adaptation, climate change, corrosion, cost, damage assessment, decision making, extreme events, fatigue life, hazards, hazard mitigation, inspection, life-cycle performance, maintenance, management, NDT methods, optimization, redundancy, reliability, repair, retrofit, risk, robustness, resilience, safety, stochastic control, structural health monitoring, sustainability, uncertainties and vulnerability. Applications include bridges, buildings, dams, marine structures, pavements, power distribution poles, offshore platforms, stadiums and transportation networks. This up-to-date overview of the field of maintenance and safety of aging infrastructure makes this book a must-have reference work for those involved with structures and infrastructures, including students, researchers and practitioners.

A growing number of urban inhabitants are aware of pressing environmental concerns. This book aims to provide information about relevant environmental quality criteria in urban construction settings, before methods are proposed for assessing these criteria. These will be extremely helpful to eco-building designs, commencing from the very early stages of a project (site selection, program, architectural designs) to the detailed design, construction and management of buildings. The book covers eco-technologies in the field of energy and water conservation, renewable energy, waste management and environmentally-friendly materials, but does not lose sight of comfort and health aspects.

3 4 5 6 7 8 9 1011 1 2 31 The continual effort to improve performance in business processes attracts 4 increasing attention in research and industry alike. The impact of design 5 development performance on the overall business positions this area as an 6 important performance improvement opportunity. However, design devel- 7 opment is characterised by novelty, uniqueness and non-repeatability, which 8 provides particular challenges in de?ning, measuring and managing its 9 performance to achieve improvement. 2011 This book explores the support provided by both general research in busi- 1 ness process performance and design research for supporting performance 2 improvement in design development. The nature of design development in industrial practice is further revealed, and requirements for its modelling and 3 analysis to achieve improvement are highlighted. 4 A methodology for the modelling and analysis of performance in design 5 development that encapsulates a formalism of performance and an approach 6 for its analysis is established. The formalism is composed of three models, 7 which capture the nature of design development performance and support its 8 2 measurement and management. The E model formalises and relates the key 9 3011 elements of performance, i. e. , ef?ciency and effectiveness. The Design Activity 1 Management (DAM) model distinguishes design and design management 2 activities in terms of the knowledge processed, while the Performance 3 Measurement and Management (PMM) model describes how these activities 4 relate within a process of measuring and managing performance.

The interaction phenomenon is very common between different components of a mechanical system. It is a natural phenomenon and is found with the impact force in aircraft landing; the estimation of degree of ripeness of an apple from impact on a beam; the interaction of the magnetic head of a computer disk leading to miniature development of modern computer; etc. Uncertainty in some of them would lead to inaccurate analysis results on the behavior of the structure. The interaction force is difficult to measure unless instruments have been installed during construction for this purpose. Some of the interaction problems are difficult to quantify due to the lack of thorough knowledge on the interaction behavior. Analytical skills are required to estimate the interaction forces of the mechanical system in order to enable advanced developments in different areas of modern technology. This volume provides a comprehensive treatment on this topic with the vehicle-bridge system for an illustration of the moving load problem. It covers a whole range of topics, including mathematical concepts of the moving load problems with continuous beams and plates, vehicle-bridge interaction dynamics, weigh-in-motion techniques, moving load identification algorithms in the frequency-time domain, in the time domain and in the state space domain, techniques based on the generalized orthogonal function expansion and on the finite element formulation. The methods and algorithms can be implemented for on-line identification of the interaction forces. This book is intended for structural engineers and advanced students who wish to explore the benefit of interaction phenomenon and techniques for identification of such interaction forces. It is also recommended for researchers and decision makers working on the operation and maintenance of major infrastructures and engineering facilities.

Rapid advances in computational methods and computer capabilities have led to a new generation of structural identification strategies. Robust and efficient methods have successfully been developed on the basis of genetic algorithms (GA). This volume presents the development of a novel GA-based identification strategy that contains several advantageous features compared to previous methods. Focusing on structural identification problems with limited and noise contaminated measurements; it provides insight into the effects of various identification parameters on the identification accuracy for systems with known mass. It then proposes a generalization for systems with unknown mass, stiffness and damping properties. The GA identification strategy is subsequently extended for structural damage detection. The findings of the output-only strategy and substructural identification represent a great leap forward from the practical point of view. This book is intended for researchers, engineers and graduate students in structural and mechanical engineering, particularly for those interested in model calibration, parameter estimation and damage detection of structural and mechanical systems using the state-of-the-art GA methodology.
