From jet engine noise that generates vibrations in the structure of an aircraft, to the sound radiation from the hull of a ship or submarine that makes it identifiable, an understanding of structural acoustics is key in the design process in maritime, automotive, aerospace, and architectural engineering. Building on classic works in the field, Structural Acoustics: Deterministic and Random Phenomena presents fundamental concepts, relations, and simplified methods for calculating complex problems associated with vibrations and noise issues of automobiles, ships, submarines, and aircraft. This practical reference studies the response of structures and media that are coupled with a fluid and are under static, dynamic, and random loading. Simplified solutions to complicated problems Starting with a review of the fundamentals of acoustics and structural acoustics, the book discusses the response of the beams, plates, and shells that compose most built-up structures before providing methods for solving problems of built-up systems, including a procedure for computing the response of an elastic or viscoelastic media without resorting to a large computer program. Building on this analysis, the second section develops the analysis for random loading, which can also be applied to geophysical phenomena and viscoelastic media. Proceeding from the fundamental aspects of simple structures to more complicated cases with more involved loading, the book presents formulas and applications for random loading. By providing a fundamental understanding of sound radiation in air and water, this book shows readers how to solve structural and acoustical problems. An important reference for those working in the area of acoustics and vibration analysis, it also includes computer programs for acoustical analysis available at www.crcpress.com.

This Research Topic on 'Healthy and Energy Efficient Buildings' focuses on the emerging need for sustainable and healthy indoor environments. The built environment contributes significantly to energy consumption and environmental degradation, leading to adverse effects on human health and well-being. Therefore, this Research Topic aims to bring together cutting-edge research that addresses the complex interplay between building energy efficiency and occupant health. The scope of the Research Topic covers topics such as energy efficiency, indoor environmental quality, sustainable energy, health and well-being, building codes and standards, energy management and green building practices. The ultimate goal of the Research Topic is to promote sustainable building practices and enhance the well-being of building occupants while reducing the environmental impact of buildings. While energy efficiency has become a top priority in building design, there has been less emphasis on creating indoor environments that are conducive to good health. To achieve the goal of this Research Topic, recent advances in building design, construction, and operation must be incorporated. These include the use of advanced materials and technologies, such as smart sensors and automation systems that can monitor and control indoor air quality, temperature, and lighting levels to create optimal indoor conditions for occupants. Additionally, the integration of renewable energy sources, such as solar and wind power, can help reduce the carbon footprint of buildings. In order to promote healthy buildings, there is a need for more research on the impact of building design and materials on indoor air quality and occupant health. This includes exploring the use of natural ventilation and passive cooling strategies, as well as the use of low-emitting materials and finishes that do not off-gas harmful chemicals. This Research Topic seeks to address the need for sustainable buildings that prioritize both energy efficiency and occupant health.

This book presents simple design paradigms related to lightweight design, that are derived from an in-depth and theoretically sound analysis based on Pareto theory. It uses numerous examples, including torsion and inflated tubes, to fully explain the theories discussed. Lightweight Construction Principles begins by defining terms in relation to engineering design and optimal design of complex mechanical systems. It then discusses the analytical derivation of the Pareto-optimal set, before applying analytical formulae to optimal design of bent beams. The book moves through numerous case studies of different beam and tube construction including beams subject to bending, thin walled tubes under torsion and truss structures. This book will be of interest to researchers and graduate students in the field of structural optimisation and multi-objective optimization, as well as to practitioners such as design engineers.
