Download or read book Ageing of Infrastructure written by Frank Collins and published by CRC Press. This book was released on 2018-09-21 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "This book presents the latest scientific research and application practice findings in the engineering field of "maintenance and safety of aging infrastructure." The selected invited contributions will 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 (buildings, bridges, lifelines, etc) for minimization of losses and life-cycle-cost. Cost-competent maintenance and management of civil infrastructure requires balanced consideration of both the structure performance and the total cost accrued over the entire life-cycle. Another major problem is that the structure performance is usually reduced during its functioning due to environmental and other factors. Thus, current structural condition state is usually assessed by visual inspection or more advanced automatic structural health monitoring techniques. Furthermore, maintenance managers often require a list of prioritized maintenance interventions for civil infrastructure on an annual and/or long-term basis. Various unavoidable uncertainties associated with both randomness (i.e., aleatory uncertainty) and imperfect knowledge (i.e., epistemic uncertainty) also play a crucial role in management and maintenance of engineering systems. Taking into account the aforementioned issues, this volume aims to present the recent developments of life-cycle maintenance and management planning for deteriorating civil infrastructure considering simultaneously multiple and often competing criteria in terms of condition, safety and life-cycle cost"--
Download or read book Aging Shaking and Cracking of Infrastructures written by Victor E. Saouma and published by Springer Nature. This book was released on 2021-04-13 with total page 1153 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ageing and the Built Environment in Singapore written by Belinda Yuen and published by Springer. This book was released on 2018-06-28 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Aging in Asia written by National Research Council and published by National Academies Press. This book was released on 2012-07-31 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sustaining the Nation s Aging Infrastructure Systems written by David P. Hale and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrastructure systems permeate society at both the personal and business levels. These systems are taken for granted, but the implications of system breakdowns are staggering and directly impact our national competitiveness, having both immediate consequences and long lasting effects on the local, regional and national economies. Many of the infrastructure systems found in the United States have been in place far beyond their design lives. How does an organization manage these aging assets given constrained resources? This paper presents an innovative research and problem formulation method created as part of an effort by the United States Army Corps of Engineers' to develop an Asset Management Framework (AMF) to manage its aging civil infrastructure assets. This paper outlines the development of the framework using an intent-driven command and control approach, grounded by the input from dozens of practitioners, gathered through a series of interviews, surveys, and field studies. The paper describes mechanisms used to bring together economists, biologists, civil engineers, and others to create a robust AMF. The AMF will be illustrated showing transparent integration of preservation and risk mitigation initiatives, as well as budget and resource allocation processes supporting a lifecycle investment strategy for sustainability across the entire agency. The Framework's scope includes oversight of much of America's watersheds covering 1,000 coastal structures, 800 dams, 250 navigation locks, 75 hydropower plants and other assorted facilities. Lessons learned in developing this system are provided, along with its current status. The implications of this work to other industries and pubic sector agencies will be examined.
Download or read book Aging Infrastructure written by Marcia Clemmitt and published by . This book was released on 2007 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The deadly collapse in August of Minneapolis' Interstate I-35 West bridge over the Mississippi River tragically underscored the condition of the nation's highways, dams, wastewater treatment systems, electrical transmission networks and other infrastructure. Many facilities and systems are 50-100 years old, and engineers say they have been woefully neglected. Decades ago taxpayers, lawmakers and private companies found it relatively easy to ante up the huge sums needed to build vital infrastructure, but money for repairs and maintenance has been far tougher to come by in recent years. Federal and state lawmakers today often prefer to spend public dollars on high-profile convention centers and sports arenas, and anti-tax groups often fight tax hikes or utility-rate increases to pay for maintenance. But now lawmakers are debating whether aging infrastructure merits higher taxes or other measures, such as turning more highways into privately run toll roads.
Download or read book Demography and Infrastructure written by Tobias Kronenberg and published by Springer Science & Business Media. This book was released on 2011-02-09 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population ageing has been going on for many decades, but population shrinking is a rather new phenomenon. The population of Germany, as in many other countries, has passed a plateau and is currently shrinking. Demographic change is a challenge for infrastructure planning due to the longevity of infrastructure capital and the need to match supply and demand in order to ensure cost-efficiency. This book summarises the findings of the INFRADEM project team, a multidisciplinary research group that worked together to estimate the effects of demographic change on infrastructure demand. Economists, engineers and geographers present studies from top-down and bottom-up perspectives, focusing on Germany and two selected regions: Hamburg and Mecklenburg-Western Pomerania. The contributors employed a broad range of methods, including an overlapping-generations model for Germany, regional input-output models, an energy systems model, and a spatial model of the transportation infrastructure.
