Examines the concept of aging process facilities and infrastructure in high hazard industries and highlights options for dealing with the problem while addressing safety issues This book explores the many ways in which process facilities, equipment, and infrastructure might deteriorate upon continuous exposure to operating and climatic conditions. It covers the functional and physical failure modes for various categories of equipment and discusses the many warning signs of deterioration. Dealing with Aging Process Facilities and Infrastructure also explains how to deal with equipment that may not be safe to operate. The book describes a risk-based strategy in which plant leaders and supervisors can make more informed decisions on aging situations and then communicate them to upper management effectively. Additionally, it discusses the dismantling and safe removal of facilities that are approaching their intended lifecycle or have passed it altogether. Filled with numerous case studies featuring photographs to illustrate the positive and negative experiences of others who have dealt with aging facilities, Dealing with Aging Process Facilities and Infrastructure covers the causes of equipment failures due to aging and their consequences; plant management commitment and responsibility; inspection and maintenance practices for managing life cycle; specific aging asset integrity management practices; and more. Describes symptoms and causal mechanisms of aging in various categories of process equipment Presents key considerations for making informed risk-based decisions regarding the repair or replacement of aging process facilities and infrastructure Discusses practices for managing process facility and infrastructure life cycle Includes examples and case histories of failures related to aging Dealing with Aging Process Facilities and Infrastructure is an important book for industrial practitioners who are often faced with the challenge of managing process facilities and infrastructure as they approach the end of their useful lifecycle.
Creating Spaces for an Ageing Society considers the existing social science literature on shared neighbourhood spaces through the perspective of an ageing population. It asks the question; how can we use social infrastructure to build local neighbourhoods that are supportive of the social relationships we need in later life?
This self-contained book focuses on the safety assessment of existing structures subjected to multi-hazard scenarios through advanced numerical methods. Whereas the focus is on concrete dams and nuclear containment structures, the presented methodologies can also be applied to other large-scale ones. The authors explains how aging and shaking ultimately lead to cracking, and how these complexities are compounded by their random nature. Nonlinear (static and transient) finite element analysis is hence integrated with both earthquake engineering and probabilistic methods to ultimately derive capacity or fragility curves through a rigorous safety assessment. Expanding its focus beyond design aspects or the state of the practice (i.e., codes), this book is composed of seven sections: Fundamentals: theoretical coverage of solid mechnics, plasticity, fracture mechanics, creep, seismology, dynamic analysis, probability and statistics Damage: that can affect concrete structures, such as cracking of concrete, AAR, chloride ingress, and rebar corrosion, Finite Element: formulation for both linear and nonlinear analysis including stress, heat and fracture mechanics, Engineering Models: for soil/fluid-structure interaction, uncertainty quantification, probablilistic and random finite element analysis, machine learning, performance based earthquake engineering, ground motion intensity measures, seismic hazard analysis, capacity/fragility functions and damage indeces, Applications to dams through potential failure mode analyses, risk-informed decision making, deterministic and probabilistic examples, Applications to nuclear structures through modeling issues, aging management programs, critical review of some analyses, Other applications and case studies: massive RC structures and bridges, detailed assessment of a nuclear containment structure evaluation for license renewal. This book should inspire students, professionals and most importantly regulators to rigorously apply the most up to date scientific methods in the safety assessment of large concrete structures.
The book addresses the problem of ageing infrastructure and how ageing can reduce the service life below expected levels. The rate of ageing is affected by the type of construction material, environmental exposure, function of the infrastructure, and loading: each of these factors is considered in the assessment of ageing. How do international design codes address ageing? Predictive models of ageing behaviour are available and the different types (empirical, deterministic, and probabilistic) are discussed in a whole-of-life context. Life cycle plans, initiated at the design stage, can ensure that the design life is met, while optimising the management of the asset: reducing life cycle costs and reducing the environmental footprint due to less maintenance/remediation interventions and fewer unplanned stoppages and delays. Health monitoring of infrastructure can be conducted via implanted probes (wired or wireless) or by non-destructive testing that can routinely measure the durability, loading, and exposure environments at key locations around the facility. Routine monitoring can trigger preventative maintenance that can extend the life of the infrastructure and minimise unplanned and reactive remediation, while also providing ongoing data that can be utilised towards more durable future construction. Future infrastructure will need to be safe and durable, financially and environmentally sustainable over the lifecycle, thereby raising socio-economic wellbeing. The book concludes by discussing the key impacting factors that will need to be addressed. The author brings a strong academic and industry background to present a resource for academics and practitioners wishing to address the ageing of built infrastructure.
The population of Asia is growing both larger and older. Demographically the most important continent on the world, Asia's population, currently estimated to be 4.2 billion, is expected to increase to about 5.9 billion by 2050. Rapid declines in fertility, together with rising life expectancy, are altering the age structure of the population so that in 2050, for the first time in history, there will be roughly as many people in Asia over the age of 65 as under the age of 15. It is against this backdrop that the Division of Behavioral and Social Research at the U.S. National Institute on Aging (NIA) asked the National Research Council (NRC), through the Committee on Population, to undertake a project on advancing behavioral and social research on aging in Asia. Aging in Asia: Findings from New and Emerging Data Initiatives is a peer-reviewed collection of papers from China, India, Indonesia, Japan, and Thailand that were presented at two conferences organized in conjunction with the Chinese Academy of Sciences, Indian National Science Academy, Indonesian Academy of Sciences, and Science Council of Japan; the first conference was hosted by the Chinese Academy of Social Sciences in Beijing, and the second conference was hosted by the Indian National Science Academy in New Delhi. The papers in the volume highlight the contributions from new and emerging data initiatives in the region and cover subject areas such as economic growth, labor markets, and consumption; family roles and responsibilities; and labor markets and consumption.

This book contains a collection of studies that have been conducted among older residents in Singapore. Different methods, from surveys to crowd sourcing, have been used to investigate the older adults’ lived experiences and social participation in the residential environment. The findings reveal that older residents interact with the built environment in ways that reflect their changing capabilities and lifestyles. Since the built environment – where we live and go – can have an important impact on our daily lives, especially among older people, understanding these experiences and perceived needs is important to help older individuals age within their community.
This long-term examination of future infrastructure needs examines what will be required, how it will be financed, and how such factors as climate change, globalisation, and urbanisation will affect these needs.
"Recommended."--CHOICE: Current Reviews for Academic Libraries "Coughlin and DíAmbrosioís edited volume is a welcome contribution to highlighting this issue for gerontologists. The collection is an informative and useful reference for students, researchers, practitioners, planners, and policy analysts"--The Gerontologist This solution-focused volume fills a gap in the literature by addressing the key issues around mobility and transportation for the aging Baby Boomer generation--issues that will be significantly different than those of previous generations of older adults. This new generation, many of whom will continue to work past the traditional retirement age and expect to pursue an active lifestyle, may have to confront new transportation technology, the need to use public transportation, and ways to continue driving safely as their eyesight fades and reaction time slows down. This volume examines many of the issues faced by policymakers, transportation officials, vehicle manufacturers, health and human services professionals, and aging adults themselves as the largest generation prepares to enter late adulthood. The volume's editors are both at the MIT AgeLab, whose multi-disciplinary team designs, develops and deploys innovations to enhance quality of life for aging populations. Through the contributions of a diverse group of theorists and practitioners, including recommendations from the National Older Driver Safety Advisory Council, a collaboration between AARP's Driver Safety Program and the MIT AgeLab, the book discusses several key topics pertinent to Aging America and transportation. Among them are the changing demographics of the population, how this generation's lifestyle choices affect mobility, technology trends in private vehicles, changes in the infrastructure and transportation system, the "new" older driver, and issues of safety and education among older drivers. This book also explores practical solutions and strategies, such as new transportation options and innovations that will significantly impact the future of mobility for older adults, for keeping these seniors active and mobile well into their later years. Key Features: Focuses on the unique mobility needs of the aging Baby Boomer generation Provides practical solutions and strategies for policy changes to enhance the mobility of older adults Examines issues faced by policymakers, transportation officials, vehicle manufacturers, health and human services professionals, and aging adults Discusses strategies for updating the infrastructure and transportation system, driving safety education for older drivers, and trends in private vehicle innovations
