Strengthening of Concrete Structures: Unified Design Approach, Numerical Examples and Case Studies
by Amr AbdelrahmanThis book presents unified design approach for strengthening concrete members with different techniques such as concrete, steel, and FRP jacketing. Preference between the various techniques is explained in light of strengthening limits, procedures, and application for each case. Examples for evaluation of existing structures and design equations for strengthening concrete elements are presented based on the ACI design codes and standards. Numerical examples are also given for different strengthening techniques with illustrations for the construction methodology and detailing for each case.Several case studies are explained starting from problem diagnosis, structure analysis, proposal for different strengthening methodologies, and implementation procedure for the selected scheme. The case studies include structures subjected to gravity loads, lateral loads, elevated temperature, and differential settlement of the foundations. It addresses design and construction errors, environmental impact, and soil movement. The case studies include conventional reinforced concrete, post-tensioned, and precast concrete members.
Strengthening of Concrete Structures with Adhesively Bonded Reinforcement: Design and Dimensioning of CFRP Laminates and Steel Plates
by Konrad Zilch Roland Niedermeier Wolfgang FinckhDesign and construction in existing contexts is becoming increasingly important, and often the structures - sometimes of historical interest - can be preserved easily and at minimum cost by employing strengthening measures. Existing concrete members can be strengthened by using adhesives to bond additional reinforcing elements onto or into those members. This book explains the design rules, together with their background, and uses examples to illustrate their use, specifically for slabs, beams and columns. Concrete member strengthening measures can take the form of, for example, flexural strengthening with externally bonded (surface-mounted) CFRP strips, CF sheets and steel plates, flexural strengthening with CFRP strips bonded in slits (near-surface-mounted reinforcement), shear strengthening with externally bonded CF sheets and steel plates, and column strengthening with CF sheets as confining reinforcement. The explanations and background information provided are mainly based on the new German guideline "Strengthening of Concrete Members with Adhesively Bonded Reinforcement" by the German Committee for Structural Concrete (DAfStb). This is the first European guideline to regulate this topic in the form of a supplement to the Eurocode. As it is planned to produce a document in a future Eurocode 2, the DAfStb guideline serves as a starting point. The authors are extensively involved in the planning, design, operation and inspection of buildings for preservation and reconstruction, and in the updating of European Technical Approval Guidelines (ETAGs) and design rules. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

Strengthening the Human Right to Sanitation as an Instrument for Inclusive Development (IHE Delft PhD Thesis Series)
by Pedi Chiemena ObaniOver a third of the current 7.3 billion people worldwide are burdened with poor sanitation services. The resulting social, relational and ecological exclusion make the realisation of the human right to sanitation (HRS) a critical concern development concern. However, the literature has evolved in a largely compartmentalised manner, focusing on the formal recognition of the HRS in domestic legal systems, without sufficiently addressing the drivers of poor sanitation services. This research expounds on the impact of the HRS on human wellbeing and the environment within the context of a developing country like Nigeria as a case study. The findings show that contrary to the focus in the literature, the drivers of poor sanitation services are not confined to legal factors, such as the formal recognition of the HRS within domestic legal systems. Rather, the drivers include social, economic and environmental limitations to improved sanitation services. Based on the findings, the book argues that the focus in the literature on the formal recognition of the HRS in national legal systems is insufficient for tackling the main drivers of poor sanitation services. It is therefore necessary to reformulate the HRS discourse using complementary governance instruments that advance social, relational and ecological inclusion.
Stress and Human Performance (Applied Psychology Series)
by Eduardo Salas James E. DriskellThe pace of life in our high technology world has quickened. Industries that do not become more efficient, often by requiring a faster production turnaround with less slack, are superseded. Because of this, workers face an environment in which they must perform under more time pressure and under greater task load, in which stress is more prevalent, and in which consequences of poor performance are more critical than ever before. The dominant, if unstated, psychoanalytic paradigm underlying much stress research over the past fifty years has led to an emphasis on coping and defense mechanisms and to a preoccupation with disordered behavior and illness. Accordingly, almost any book with "stress" in the title will invariably devote a considerable amount of pages to topics such as stress-related disorders, clinical interventions, stress and coping, psychopathology, illness, and health issues. This book presents basic and applied research that addresses the effects of acute stress on performance. There are a large number of applied settings that share the commonalities of high demand, high risk performance conditions, including aviation; military operations; nuclear, chemical, and other industrial settings; emergency medicine; mining; firefighting; and police work, as well as everyday settings in which individuals face stressors such as noise, time pressure, and high task load. This book focuses directly on the effects of acute stress-- defined as intense, novel stress of limited duration--on performance. The effects of stress on task performance, decision making, and team interaction are discussed, as well as the interventions used to overcome them.

Stress Challenges and Immunity in Space: From Mechanisms to Monitoring and Preventive Strategies
by Alexander ChoukérThis book explains how stress – either psychological or physical – can activate and/or paralyse human innate or adaptive immunity. Adequate immunity is crucial for maintaining health, both on Earth and in space. During space flight, human physiology is specifically challenged by complex environmental stressors, which are most pronounced during lunar or interplanetary missions. Adopting an interdisciplinary approach, the book identifies the impact of these stressors – the space exposome – on immunity as a result of (dys-)functions of specific cells, organs and organ networks. These conditions (e.g. gravitation changes, radiation, isolation/confinement) affect immunity, but at the same time provide insights that may help to prevent, diagnose and address immune-related health alterations. Written by experts from academia, space agencies and industry, the book is a valuable resource for professionals, researchers and students in the field of medicine, biology and technology.The chapters “The Impact of Everyday Stressors on the Immune System and Health”, “Stress and Radiation Responsiveness” and “Assessment of Radiosensitivity and Biomonitoring of Exposure to Space adiation” are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Stress Concentrations in Laminated Composites
by Seng C. TanFrom the Author's PrefaceThe objective of this book is to provide a thorough and systematic study of the problem of laminated composites containing stress concentrations. Stress concentrations are introduced in laminated plates in the forms of circular holes, elliptical openings and straight cracks. These forms of cutouts have many practical applications, and are familiar to most engineers. Stress concentrations exist in all known structural components. Stress concentrations have great practical importance because they are normally the cause of failure. In addition to stress analyses of laminated composites, we need more fundamental understanding of the failure mode, the failure criterion, the effects on global laminate response, and the design of composites in the presence of stress concentrations. In this book, all the subjects studied are closely related to the problem of stress concentrations in laminated composites . . . . All the models are verified with many experimental results. The underlying objective of this comprehensive study is to give the readers an in-depth and thorough understanding of the problem of stress concentrations in composites. This book is the first to address the problem of laminated composites containing stress concentrations in a systematic way.
