This open access book is compilation of selected papers from 2nd International Conference on Innovative Solutions in Hydropower Engineering and Civil Engineering (HECE 2022). The work focuses on ...novel techniques for topics in hydropower and sustainable development, maximizing and communicating the multiple benefits of hydro, the food-water-energy nexus approach, synergy among the renewables, making hydro more competitive (managing and mitigating risk), regional development through power trading, hydropower technology, civil engineering, materials for dams and appurtenant works, advances in design and construction techniques, recent developments in dam construction, monitoring and engineering for safe structures and sites. Hydropower offers significant potential for carbon emissions reductions. The installed capacity of hydropower by the end of 2008 contributed 16% of worldwide electricity supply, and hydropower remains the largest source of renewable energy in the electricity sector. The contents make valuable contributions to academic researchers, engineers in the industry, and regulators of hydropower and civil engineering authorities.
Effective mechanical properties of fiber-reinforced composites strongly depend on the microstructure, including the fibers' orientation. Studying this dependency, we identify the variety of fiber ...orientation tensors up to fourth-order using irreducible tensors and material symmetry. The case of planar fiber orientation tensors, relevant for sheet molding compound, is presented completely. Consequences for the reconstruction of fiber distributions and mean field homogenization are presented.
For the first time new connectors were realized using densified veneer wood (DVW). Initially, the DVW surface was modified to increase the friction between the connector and the timber part in the ...shear plane and thus significantly increase the load-carrying capacity of the connection. Friction tests were carried out to determine the friction coefficients of the surfaces. Based on the friction tests, the behavior of the surfaces in combination with inclined screws was investigated.
This is an open access book. This book focuses on the durability problems of existing prestressed concrete (PC) structures caused by strand corrosion, clarifies the mechanical behavior of corroded ...prestressing strands, corrosion-induced cracking, bond degradation, prestress loss and structural performance deterioration, and proposes the corresponding prediction models. Its aim is to provide the knowledge, tools, and methods to understand the deterioration phenomena of PC structures. We hope that this text may be useful for those who work in the field of civil engineering. It is suitable for teachers and students majoring in civil engineering in universities, and researchers in the field of civil engineering. It is also suitable for practitioners of design institutes, construction units, supervising units and traffic management departments.

Proposed in the early 1990s, the enhanced assumed strain (EAS) method is one of the probably most successful mixed finite element methods for solid mechanics. This cumulative dissertation gives a ...comprehensive overview of previous publications on that method and covers recent improvements for EAS elements. In particular, we describe three key issues of standard EAS elements and develop corresponding solutions.
This is an open access book. The aim of this book is to provide a thorough grounding in rainfall-induced landslides from three aspects: the coupling effect of hydraulic and mechanic; the analytical, ...numerical, and physical simulation methods, and the controlling factors underlying the problem of rainfall-induced landslides. The improved numerical methods, nonlinear, and linear iterative methods which can be used to address the related unsaturated infiltration problems are also presented. This book is an essential reading for researchers and graduate students who are interested in rainfall infiltration, landslides, slope stability, and geohazards in fields of civil engineering, engineering geology, and earth science. The book is written to guide professional engineers and practitioners in slope engineering and geohazard management. This book can enhance their understanding of rainfall-induced landslides, help them analyze a specific problem, prevent landslides, and design engineering slopes according to the local soil and climate conditions.
The concrete industry is facing the major challenge of drastically reducing CO₂ emissions and thus contributing to sustainability and climate protection. In these conference proceedings, we would ...like to focus on how we can make the concrete industry not only more sustainable but also more cost-efficient by adopting the circular economy in the building sector. In particular, we focus on the recycling of concrete and the reuse of entire concrete components.
This open access book is an efficient and economic approach for mitigating the seismic damage of low-rise buildings. This book presents various aspects of SB structures, including their fundamentals, ...dynamic analysis procedures, seismic response characteristics, design methods, and practical applications. It contains a comprehensive study on the influence of various structural and ground motion characteristics on the responses of SB structures, which is particularly helpful for the readers to fully understand the behavior of SB structures. Researchers and engineers in the field of structural engineering and earthquake engineering will benefit from this book.
Seemingly detached from attractive mobility alternatives in cities the car remains highly relevant in personal mobility. In order to investigate the role of the car, a new survey concept for a ...multidimensional analysis of urban mobility is presented: the travel skeleton. The modular design combines the collection of everyday trips in a typical week with occasional long-distance trips in a quasi-longitudinal approach. The concept also captures associated psychographic characteristics.
