Capturing the mechanical behaviour of engineered soils requires new constitutive models tailored for stabilising materials (biogenic, polymeric, etc.) and methods for their inclusion in soil. In this book and to accommodate such an integrated approach, a range of non-conventional materials are first discussed from physio-chemo-mechanical, circularity, and socioeconomic perspectives. Contributions continue with tailored methods for the determination of advanced mechanical properties and methods to capture the response of grand systems constituting such materials. The book concludes with contributions about how materials and methods should and are combined to develop new soil models. The integrated approach followed in this book makes it of interest to geotechnical researchers, as well as design engineers, policymakers, and planners¿hence the broad spectrum of built environment stakeholders.

Ground vibrations during earthquakes cause deformation and forces in the structures. The earthquake of the late 19th and early 20th centuries triggered several early advancements in science and engineering. The Bhuj earthquake of 2001 was the first instance of engineering causing the collapse of modern multi-storey buildings in India. The main principle used in the seismic design of the structure is capacity design. This principle allows the design of dissipative members, where the energy dissipation will be concentrated during a seismic event, while the non-dissipative members are protected from failure by providing them with a level of over strength such that they can resist the maximum force developed by the plasticization in the dissipative zone. Capacity design principles are; Global plastic mechanism of structure, Identification of dissipative and non-dissipative zones in the structure, and Provision of proper detailing to ensure maximum ductility for dissipative zones. In recent days because of rapid population growth, civil engineering structures like high-rise buildings, long-span bridges, huge industrial buildings, etc., have become more common. These structures are prone to damage during natural disasters and the consequences of failure are catastrophic. Hence some precautions need to be taken during the design of structures. However, these structures cannot be made completely safe against such calamities. Some extraordinary situations may cause damage to the structures or may lead to collapse. So it is important to make the structure safe even after extraordinary situations of natural disasters. Structures can be protected against natural hazards by using a lateral load resisting system or structural damping system or energy dissipating system. Steel LFRS has been used in all forms the structures to resist lateral forces like earthquake and wind forces. This system provides various advantages such as cost reduction, speed of construction, reduced foundation cost, and increased ductility of the structure. Using steel as construction material economic designs can be achieved that provide life safety for the occupants. Commonly used structural typologies for a steel building to resist the lateral forces are, Moment resisting frames (MRF), Braced frames, and Steel plate shear walls.

In this book, we proposed velocity-free localization methods for acoustic and microseismic sources. This method does not require predetermination of wave velocity, which is a dynamically adjusted free real-time parameter. These methods solve the problem of large localization error caused by the difference between measured wave velocity and actual wave velocity in the source area and greatly improve the positioning accuracy.They are suitable for complex structures where the wave velocity changes dynamically in time and space, such as mines, bridges, buildings, pavements, loaded mechanical structures, dams, geothermal mining, oil extraction, and other engineering fields. This book includes progress in the development of localization methods, factors affecting the accuracy of source localization, analytical methods without the pre-measured wave velocity, velocity-free numerical methods for localizing acoustic sources, combined optimal velocity-free localization methods, velocity-free source localization considering complex paths of spatial structures, and theories as well as some cases of engineering applications of these methods.

Railway Noise and Vibration: Mechanisms, Modelling, and Means of Control, 2nd Edition provides a complete overview of the state of the art in rail noise and vibration theory and modelling. This book describes each source of noise and vibration, such as rolling noise, curve squeal, bridge noise, aerodynamic noise, ground vibration and ground-borne noise, and vehicle interior noise in a systematic way, covering relevant theoretical modelling approaches and their practical implementation, with extensive examples of noise control technology applied at source. Noise and vibration are key obstacles to further development of railway networks worldwide for high-speed intercity traffic, freight and suburban metros and light-rail systems. With noise problems all too often dealt with inefficiently due to a lack of understanding of the problem, this new edition is an invaluable reference for all those working with noise and vibration from railways, whether in industry, consultancy, or academic research.

This book includes peer-reviewed articles from the Third World Conference on Floating Solutions WCFS 2023 Japan with an aim to pioneer the SDGs and Next SDGs by making the most use of oceans and water. In recent years, the safety and security of people's lives around the world have been threatened by frequent floods and rising sea levels attributable to climate change. The COP 26 has set a common global goal of limiting the temperature rise to 1.5 degrees Celsius above pre-industrial levels. It is an urgent task to cope with climate change as well as to utilize decarbonized and renewable energy. The UN is promoting the SDGs which aim to achieve 17 Goals between 2015 and 2030. However, efforts to reach the Goals will not end in 2030 but will be an ongoing challenge for humanity beyond 2030. Here, we tentatively call the Goals to be achieved after the SDGs as "Next SDGs." Ocean and water have the potential to provide solutions to the disasters such as flooding and sea level rise due to climate change. In this context, WCFS 2023 presents ocean and water as the urban infrastructure and explores new technology and feasible solutions. In particular, it is necessary to consider urban planning, marine architecture, port planning connecting land and sea, disaster prevention, renewable energy, and food production on the sea and water. Further, it is indispensable that knowledge, experience, dream, and strong desire to realize these challenges are supported by a diversity of people.

Increased environmental and energy concerns have renewed global interest in raw earth as a building material. Low-energy requirements, low-cost, high availability at construction sites, and favorable engineering properties make (EBMs) an attractive alternative to conventional cement-based construction materials. Though the use of native binders to improve soil properties has garnered attention in recent literature, the available knowledge has not been covered in a single document. This book highlights the key soil properties that determine the mechanical performance of earthen building materials, importance of unsaturated soil mechanics in the engineering behavior of earthen building materials, the different types of stabilizers used to improve the engineering performance of earthen building materials including the use of select native binders, the characteristics of compressed earth blocks stabilized with cement and cement + wood ash additives and the improvement in the engineering properties of adobes stabilized with plant fibers and cow dung.
