Available in PDF, EPUB and Kindle. Book excerpt: Optimierungsgestütztes Entwerfen und Bemessen liefert neuartige Methoden, bewehrten Beton besonders effizient einzusetzen. Dabei wird die mathematische Optimierung auf die praktischen Probleme des Betonbaus angewendet. Ziel ist es, sparsam mit dem weltweit meistverwandten Baustoff Stahlbeton umzugehen und damit den CO2-Ausstoß aus der Zement- und Stahlherstellung und den Ressourcenverbrauch an Kies, Sand und Wasser substanziell zu reduzieren. Drei Themenbereiche sind angesprochen. Erstens, die Strukturfindung, also die Frage nach der richtigen äußeren Form, dass schlanke, nach dem Kraftfluss ausgerichtete Tragwerke entstehen. Baustoffgerecht sind sie weitgehend auf Druck beansprucht. Zweitens, die Bewehrungsführung, die sich am inneren Kraftfluss orientiert. Vorteile ergeben sich gerade für Scheiben, volumenartige Bauteile, an Lasteinleitungsbereichen und Aussparungen. Es entstehen anschauliche, direkt in Bewehrungen umsetzbare Fachwerkmodelle. Dritter Entwicklungsschritt ist die Behandlung von Querschnitten. Sie werden in ihrer Form optimiert und in ihrer Bewehrung bemessen. Dies gilt auch für anspruchsvolle Beanspruchungen (zweiachsige Biegung) und nahezu beliebige Formen. Eine Parametrisierung ermöglicht die allgemeingültige Übertragung auf ganze Klassen von Querschnitten. Die optimierungsgestützten Methoden werden vertieft und anschaulich beschrieben. Sie sind universell anwendbar und unabhängig von Normen, Betonarten und Bewehrungen. Sie gelten für normalfeste bis zu ultrahochfesten Betonen, für Bewehrungen aus Stahl, Carbon oder Glasfasern und für Bewehrungsstäbe als auch -fasern. Zahlreiche Abbildungen und Berechnungsbeispiele verdeutlichen die Anwendung. Zudem werden praktische Umsetzungen vorgestellt, darunter ultra-leichte Stahl-Beton-Balken, schlanke Solarkollektoren aus Beton und verbesserte Bewehrungslayouts für Tunnelschalen. Das Buch richtet sich gleichermaßen an Studierende, Forscher und Praktiker.

Available in PDF, EPUB and Kindle. Book excerpt: Performance-Based Optimization of Structures introduces a method to bridge the gap between structural optimization theory and its practical application to structural engineering. The Performance-Based Optimization (PBO) method combines modern structural optimisation theory with performance based design concepts to produce a powerful technique for use in structural design. This book provides the latest PBO techniques for achieving optimal topologies and shapes of continuum structures with stress, displacement and mean compliance constraints. The emphasis is strongly placed on practical applications of automated PBO techniques to the strut-and-tie modelling of structural concrete, which includes reinforced and prestressed concrete structures. Basic concepts underlying the development of strut-and-lie models, design optimization procedure, and detailing of structural concrete are described in detail. Alternative approaches to topology optimization are also introduced. The book contains numerous practical design examples illustrating the nature of the load transfer mechanism of structures.

Download or read book Advanced Reinforced Concrete Design inkl E Book als PDF written by Georgios Gaganelis and published by Ernst & Sohn. This book was released on 2022-07-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete is the most used building material. Its main component, cement, however, accounts production- related for up to 10 % of global CO2 emissions and is therefore a major contributor to human-induced climate change. Due to its low tensile strength, concrete must be further enhanced in tension with adequate reinforcement, such as steel. Producing the latter therefore additionally impacts the environment. Consequently, reducing the material amount for design and construction of structures, thus lowering material- and transport-induced emissions, represents a key element to climate protection. In this context, meeting the essential requirements ? sustainability, serviceability, durability ? is yet indispensable. The book presents innovative optimization aided design methods for concrete structures. Mathematical optimization is applied to practical problems of structural concrete at each level: from external, through internal structure identification to cross-section design. It is shown how to design resource-efficient structures following the flux of forces, how to optimally adapt reinforcement layouts to the internal force flow, and how to efficiently cope with demanding cross-sectional design tasks such as biaxial bending. The optimization aided design methods are discussed in detail and described vividly. They are independent of standards, concrete material (normal to ultra-high performance) and reinforcement type (steel fibers to carbon bars), thus universally applicable. The book illustrates the different approaches with numerous figures and calculation examples. Existing applications in structural engineering are presented to demonstrate the potential of optimization aided design concepts, including ultra-lightweight hybrid beams, thin concrete solar collectors, and improved reinforcement layouts for tunnel lining segments.

This book was released on 2020-03-20 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforced concrete structures are one of the major structural types and must adhere to design regulation codes. It is ideal to find the best design (section dimension, material type, and amount of reinforcement) with the minimum cost providing the design constraints (design formulation considering loading of structure). Metaheuristic methods inspired by natural phenomena can consider design constraints by combining the analyses of formulation of reinforced concrete structures with an iterative numerical algorithm using several convergence options of random generation of candidate design solutions. Metaheuristic Approaches for Optimum Design of Reinforced Concrete Structures: Emerging Research and Opportunities is a pivotal reference source that focuses on several metaheuristic algorithms and the design of several types of structural members. Additionally, retrofit applications and seismic design issues are considered for readers in earthquake zones. Highlighting a wide range of topics including algorithms, design variables, and retrofit design, this book is ideally designed for architects, engineers, urban designers, government officials, policymakers, researchers, academicians, and students.

Download or read book Reinforced Concrete Beams Columns and Frames written by Jostein Hellesland and published by John Wiley & Sons. This book was released on 2013-02-13 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is focused on the theoretical and practical design of reinforced concrete beams, columns and frame structures. It is based on an analytical approach of designing normal reinforced concrete structural elements that are compatible with most international design rules, including for instance the European design rules – Eurocode 2 – for reinforced concrete structures. The book tries to distinguish between what belongs to the structural design philosophy of such structural elements (related to strength of materials arguments) and what belongs to the design rule aspects associated with specific characteristic data (for the material or loading parameters). A previous book, entitled Reinforced Concrete Beams, Columns and Frames – Mechanics and Design, deals with the fundamental aspects of the mechanics and design of reinforced concrete in general, both related to the Serviceability Limit State (SLS) and the Ultimate Limit State (ULS), whereas the current book deals with more advanced ULS aspects, along with instability and second-order analysis aspects. Some recent research results including the use of non-local mechanics are also presented. This book is aimed at Masters-level students, engineers, researchers and teachers in the field of reinforced concrete design. Most of the books in this area are very practical or code-oriented, whereas this book is more theoretically based, using rigorous mathematics and mechanics tools. Contents 1. Advanced Design at Ultimate Limit State (ULS). 2. Slender Compression Members – Mechanics and Design. 3. Approximate Analysis Methods. Appendix 1. Cardano’s Method. Appendix 2. Steel Reinforcement Table. About the Authors Jostein Hellesland has been Professor of Structural Mechanics at the University of Oslo, Norway since January 1988.

The lectures and papers have been divided into two volumes to reflect the dual themes of the Institute namely Optimization and Decision Support Systems in Civil Engineering. Planning for this ASI commenced in late 1986 when Andrew Templeman and I discussed developments in the use of the systems approach in civil engineering. A little later it became clear that much of this approach could be realised through the use of knowledge-based systems and artificial intelligence techniques. Both Don Grierson and John Gero indicated at an early stage how important it would be to include knowledge-based systems within the scope of the Institute. The title of the Institute could have been: 'Civil Engineering Systems' as this would have reflected the range of systems applications to civil engineering problems considered by the Institute. These volumes therefore reflect the full range of these problems including: structural analysis and design; water resources engineering; geotechnical engineering; transportation and environmental engineering.
